Knowledge of stainless steel sheet introduction

Stainless steel sheet sample surface and corrosion resistant performance is good, do not have to go through 430 stainless steel sheet  treatment such as plating color, and play the stainless steel inherent surface properties, a used in many aspects of steel, often called stainless steel. Represent properties of chrome steel, nickel chromium steel and high alloy steel. Stainless steel sheet is a universal stainless steel materials, anti rust performance than the stainless steel material. High-temperature is better, can high to 1000-1200 degrees. Stainless steel sheet has excellent stainless corrosion resistant performance, corrosion resistance and good resistance to magnetic stainless steel sheets . The oxidizing acid, derived from the experimental concentration ≤ 65% boiling temperature below the nitric acid, stainless steel sheet has strong corrosion resistance. Also has good corrosion resistance to alkali solution and most organic and Stainless Steel Sheets acid. Mechanism of stainless steel sheet antirust alloy elements form dense oxide film, isolated oxygen exposure, prevent further oxidation. So so "does not rust".

The 430 stainless steel sheets and material

Structure with 430 stainless steel sheets seamless steel pipe is widely used in chemical, petroleum, made of 430 stainless steel sheets  hot-rolled textile, medical, food, machinery and other industrial anti-corrosion pipes and structural parts and components of (extrusion, expansion) and cold drawing (rolling) seamless steel tube. 430 stainless steel sheets is used for the transmission fluid made of magnetic stainless steel sheets  hot-rolled (extrusion, expansion) and cold drawing (rolling) seamless steel tube. 430 stainless steel sheets is a general term for addition tube other than seamless pipe cross-section shape. According to the steel tube cross-section shape and size can be divided into different and wall thickness of seamless steel tube, unequal wall thickness of seamless steel tube, seamless steel tube diameter. Shaped seamless steel pipe is widely used for various stainless steel sheets  parts, tools and machinery parts. Compared with the round pipe, special-shaped tubes are generally large inertia and section modulus, bending and torsional capacity is larger, can greatly reduce the structural weight, saving steel.

Stainless steel sheets with internal 430 introduction

430 stainless steel sheets is the floorboard of stainless steel plate and acid resistant steel. 430 stainless steel sheets refers to the air resistance, steam and water, weak corrosion of steel, and acid resistant steel is resistant to acid, alkali, salt and other chemical etching medium corrosion of steel plate. Stainless steel plate since the 430 stainless steel sheets  of this century has, up to now has 90 years of history. The invention of stainless steel plate was a great achievement in the world, the development of stainless steel plate and laid an important material and technological foundation for the development of modern industry and the progress of science and technology. Stainless steel plate for many, the performance of different, it is in the development process, gradually formed a few categories. According to the organizational structure is divided into stainless steel plate (including precipitation hardening stainless steel plate), stainless steel sheets , stainless steel plate and ferrite and ferrite dual phase stainless steel plate and other four categories? According to some characteristic elements of main chemical components or steel plate in the classification, divided into chromium stainless steel, chromium nickel stainless steel plate, nickel chromium molybdenum stainless steel plate and low carbon steel plate, stainless steel plate, high molybdenum high purity stainless steel plate etc.. According to the characteristics and application of classification of steel plates, divided into nitric acid resistant stainless steel plate, stainless steel plate, resistance to acid corrosion of stainless steel plate, the stress corrosion of stainless steel plate, stainless steel plate. According to the classification features of steel plate, stainless steel plate, divided into low temperature non magnetic stainless steel plate, stainless steel plate, superplastic free cutting stainless steel plate etc..

Or divided into chromium stainless steel and nickel stainless steel plate two categories. A wide range of uses? Equipment? Typical use: pulp and papermaking equipment heat exchanger, dyeing equipment, film processing equipment, pipeline, the coastal areas of the exterior of the building materials etc..

The performance of stainless steel sheets

Uniform corrosion refers to the metal surface contact corrosion medium total corrosion phenomena. According to different demands of different indicators on corrosion, can generally be stainless steel sheet  into two categories: Stainless steel sheets refers to the corrosion in atmospheric and weak corrosive medium steel. The corrosion rate less than 0.01mm/ year, considered to be "completely corrosion; corrosion rate less than 0.1mm/ year", that is "resistance". Corrosion resistant steel tube which can corrosion in various strong corrosive medium steel. Point corrosion refers to the metal material surface most no corrosion or slight corrosion and local corrosion occurred in highly dispersed, common corrosion spot size of less than stainless steel sheet coil , depth is often greater than the surface of the aperture, the light has a shallow pit, serious and even the formation of perforation. Crevice corrosion is a macro etch pits mottled or ulcer formation occurred in the metal component in the gap, which is a kind of local corrosion. Stainless steel sheets intergranular corrosion is a selective corrosion, with the general difference is that selective corrosion, localized corrosion is a microscopic scale, and the macro is not necessarily local.
