  • Introduction of 430 ferritic stainless steel
    Aug 10, 2018

    The 430 is the steel number of ferritic stainless steel. The composition is characterized by high chromium and nickel free. 430 stainless steel is widely used in light industry, textile, construction, transportation and food processing industries, is second only to Austenitic 304 stainless steel is the most widely used steel.

    The formability, weldability and intergranular corrosion resistance of 430 stainless steel are all weaker than 304. The main reasons for its wide application lie in:

    1. nickel is not included in steel, and the cost is relatively low.

    2. Better resistance to chloride and caustic stress corrosion than 304.

    3. Cold processability, weldability and corrosion resistance are better than martensitic stainless steel.

    Among them, low price is the main reason why 430 is popular. 430 provides a more economical solution with slightly weaker performance than 304
