    Introduction:

    400 series stainless steel is a Carbon-Chromium ally, which has martensitic structure and iron, therefore, they have magnetic properties. Meanwhile, they have a good heat processing and anti-oxidization performance. Compared to carbon steel, 400 series stainless steel have a a further improvement on its physical and mechanical properties. Most 400 series can be heat treated.

     

    Advantage:

    Most 400 series stainless steel has 18% Chromium, 410 and 420 stainless steel has 13% Chromium.

    1. Cheaper than 300 series, and higher corrosive resistance than 200 series.
    2. Higher corrosive resistance than 300 series under Chloride environment.
    3. With Niobium, Titanium, copper, and aluminum elements added, the drawability, weldability, corrosion resistance

    Advantages:

    1. Raw material choices.

    All of raw stainless steel coils are from YUSCO, Baosteel, TISCO.
    From slitting to production, we care more about the tolerance and raw material mechanical parameters to guarantee the tube quality control.
