Vulnerable duplex 430 stainless steel sheets

Universality ( 1 ) applications and multi -faceted as good as austenitic stainless steel , such as its temperature must be controlled at 250 degrees Celsius.
( 2 ) its plasticity and toughness lower than the austenitic qiyi stainless steel sheet 304 , cold and hot forming process and performance ( 3 ) exists in the temperature brittle zone , the need for strict control of heat treatment and welding technology system to avoid harmful phase hurt performance.
Compared with the ferritic stainless steel , duplex stainless steel strengths are as follows :
( 1 ) better than the overall mechanical properties of ferritic stainless steel , especially plastic toughness , not like that kind of ferritic stainless steel brittle sensitive .
( 2 ) In addition to resistance to stress corrosion , the other is superior resistance to localized corrosion of ferritic stainless steels.
( 3 ) cold cold forming process performance and the performance is far superior to ferritic stainless steel .
( 4 ) is also far superior weldability of ferritic 430 stainless steel magnetic , the former general welding without preheating , without heat treatment after welding .
( 5 ) the scope of application than the ferritic stainless steel wide.

High-chromium stainless steel sheet 304 first

Good heat resistance, corrosion resistance is weak , 11% Cr, 8% of Ni.
409 - the cheapest model ( BAR ) , commonly used as automobile exhaust pipe, is a ferritic qiyi stainless steel 304 sheet ( chrome steel ) .
( High-strength chrome steel ) , good wear resistance , corrosion resistance is poor .
Similar to Brandt 's first high-chromium stainless steel this . Also used in surgical tools , can do very bright .
Good formability , but heat resistance and corrosion resistance worse .
Carbon is slightly higher , after appropriate heat treatment to obtain a higher yield strength and hardness up to 58HRC, are among the most hard stainless steel sheet 304 . The most common application example is the " razor blades ." ( Easy processing ) .
