The surface is Matt, look carefully with a little texture, but can not come out, than the general bright surface stainless steel wear, look more attractive to some. Plate has a variety of lines, a hairline, snow sand grain, and grain (fill), cross lines, cross lines, all the lines through the oil thrown hairline machine made according to the requirements of processing, and then electroplating coloring. 3, stainless steel sheet sand plate 3, stainless steel sheet sand plate Sand plate with zirconium beads by magnetic stainless steel sheets  equipment for processing in the stainless steel surface, make the surface appear slight bead granular sand surface, forming a unique decorative effect. Then electroplate .4, stainless steel sheet combination technology board According to the technological requirements, the hair lines, coating, polishing, sandblasting, etching process in the same piece of plate combination process. Then electroplate. 5, stainless steel sheet and plate Both and pattern plate, or drawing board are frosted plate one, only the surface state board this in not the same, so that is not the same.

Several state of 430 stainless steel of magnetic

430 stainless steel magnetic has the following kinds of state, state is not the same, dirt and corrosion resistance are not the same. NO.1, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment.
Surface processing  430 stainless steel magnetic  feature processing technology
2D is a shiny silver white hot shot peening + annealing pickling + cold + annealing and pickling 2B is silver white and better than 2D surface gloss and flatness of hot rolling + annealing pickling + cold + shot peening annealing and pickling + temper rolling

No.3 has a 430 stainless steel plate  gloss, coarse grain of 2D or 2B with 100~120 (JIS R6002) abrasive polishing and temper rolling
No.4 has a good gloss, fine lines on the 2D or 2B with 150~180 (JIS R6002) abrasive polishing and temper rolling
430 stainless steel magneticHL was abrasive material and hair gray stripes on 2D or 2B with the proper size of polishing the surface is continuous grinding grain

Ti stainless steel plate wherein a stabilizing element exists

stainless steel sheet in which 304 stainless steel coil‍ as a stabilizing element exists, but it is also heat resistant steel, 304 stainless steel at high aspect ratio is much better .304 plate stainless steel plate at different concentrations and different temperatures of magnetic stainless steel sheets‍ and inorganic acids, especially is a good abrasion properties in oxidizing medium, acid resistant container for the manufacture of equipment and wear lining pipelines.

Corrosion of the stainless steel plate 430

All metals and oxygen in the reaction atmosphere, an oxide film is formed on the surface. Unfortunately, the iron oxide formed on carbon steel is continued oxidation, rust expanded, forming holes. You can use paint or oxidation-resistant metals (eg, zinc, nickel and chromium) plating to ensure the steel surface, but, as people know, this protection is only a film. If the protective layer is damaged, the following steel began to rust. 430 stainless steel sheets corrosion resistance depends on chromium, but because chromium is an integral stainless steel sheets of steel, so the protection methods vary. When you add the amount of chromium reached 10.5%, atmospheric corrosion resistant steel increased significantly, but higher chromium content, although still improve corrosion resistance, but not obvious. The reason is that when the steel with a chromium alloying treatment, the type of change has become similar to the surface oxide formed on the surface of magnetism stainless steel chromium oxide of the metal. Chromium-rich oxide protects the surface of this tightly adherent to prevent further oxidation. This oxide layer is very thin, it can be seen through the surface of the natural sheen of steel, so stainless steel has a unique surface. Moreover, if the damaged surface, and atmospheric reactions exposed steel surface will self-repair, re-formation of this "passive film", continue to play a protective role. Therefore, all of the stainless steel have a common characteristic, i.e., the chromium content of more than 10.5%.

Features 430 stainless steel plate

430 stainless steel sheets containing sulfur and selenium cutting stainless steel, the main requirements for cutting and stainless steel sheet metal‍ tables Guanghao occasions. 430 stainless steel to improve machinability and high temperature bonding properties. Suitable for automatic lathes. Bolts and nuts. 

430 austenitic stainless steel is acid resistant stainless steel cutting, in order to improve the performance of the steel in the steel can be added to more than stainless steel coils manufacturers‍ molybdenum, can be resistant to erosion, product good cutting resistance and burn. after the corrosion resistance and mechanical properties of stainless steel annealing .303 to stress, tensile strength 515MPa, yield 205MPa, elongation of 40%.‍

430 stainless steel is the full shape and size of a standard metal manufacturing

430 stainless steel sheets is the full shape and size of a standard metal manufacturing, and there are many special shapes. The most commonly used product is made ​​of sheet and strip, and plate production with special products, for example, the production of hot-rolled structural steel and structural steel extrusion. And there are stainless steel 430ba‍  oval, square, rectangular and hexagonal welded or seamless steel tubes and other forms of products, including profiles, rods, wire and castings. As discussed later, in order to meet the aesthetic requirements of architects, has developed a wide variety of commercial surface processing. For example, the surface can be coil stainless steel‍ reflective or matte; may be glossy, polished or embossed; may be colored, the color of the plating or etching a pattern on the surface of stainless steel to meet the designer appearance various requirements. Surface state is easy to maintain. Just the occasional rinse can remove dust. Because of good corrosion resistance, graffiti can be easily removed or contaminated surfaces other similar surface contamination.

Typical uses 430 stainless steel plate

Most of the requirements is to maintain long-term building of the original appearance. In determining to choose the type 430 stainless steel sheets, the main consideration is the aesthetic standards required by the system to be used to clean corrosive and location of the atmosphere. However, a growing number of other applications, or just looking for the integrity of the structure is not permeable. For example, industrial building roof and side walls. In these applications, the construction cost of the owner may be more important than the aesthetic, surface and to be very clean. The effect of the use of 430 stainless steel in dry stainless steel suppliers environment is quite good. However, in rural and urban areas in order to maintain their appearance in the outdoors, they need regular cleaning. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rust. But to get the aesthetic effect of the outdoor environment, it requires the use of nickel-containing stainless steel. So, 304 stainless steel is magnetic stainless steel sheet used in curtain wall, side walls, roofs and other construction purposes, but in severe erosion of industrial or marine atmosphere, the best use of 316 stainless steel. Now, it has been fully aware of the use of stainless steel in structural applications superiority. There are several design criteria included 304 and 316 stainless steel. Because "duplex" 2205 has already good atmospheric corrosion resistance and high tensile strength and elastic limit of integration, so the European guidelines also include the steel.

430 stainless steel and 430L comparison

430L nickel than some of the more than 430 

With a little more than a nickel, and more importantly, 430 is a lot smaller than the carbon content of 430L. Local 430L at the soldering point or other processing of pitting above even better than 430. 

coil stainless steel‍ is more corrosion resistant, less carbonaceous 430L. 

430 stainless steel sheets versatile, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping bending and other thermal processing, and no stainless steel 409‍ hardening (non-magnetic, temperature -196 ° C ~ 800 ° C ). 

430L welding or eliminate stress, its excellent resistance to intergranular corrosion; in the absence of heat treatment, able to maintain good corrosion resistance, temperature -196 ° C-800 ° C.‍

403 stainless steel plate superior performance

430 stainless steel sheets are 304 stainless steel strip‍ austenitic stainless steel, 304 stainless steel plate and its performance is very similar, but due to the addition of titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium, making it effective control of the formation of chromium carbides. 

Excellent high-temperature stress in Stainless steel factory‍ stainless steel with a breaking (Stress Rupture) performance and high temperature creep resistance properties (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.

various classifications of stainless steel sheets

Classification by structure organization at stainless steel coils‍ temperature, there is martensitic, austenitic, ferritic and duplex stainless steel; by major chemical composition, can basically be divided into chromium stainless steel and chrome-nickel stainless steel two systems; according to zoning there nitric acid resistant stainless steel, acid-resistant stainless steel, water-resistant stainless steel, etc., can be divided into types by corrosion-resistant stainless steel pitting, stress corrosion of stainless steel, such as resistance to intergranular steel strips‍ of stainless steel; according to the classification features can be divided into no magnetic stainless steel sheets, cutting stainless steel, low temperature steel, high-strength stainless steel and so on. Because stainless steel has excellent corrosion resistance, formability, compatibility and a wide temperature range and other characteristics of toughness, so get too widely used in heavy industry, light industry, household items and building decoration industry and other industries .
