SX430 flat low-carbon chromium ferritic stainless steel. Mild steel at high temperatures, corrosive environments and good corrosion resistance and good resistance to oxidation . Steel is soft annealed condition , hardening during cold working is not too much or slightly stretching - bending and roll forming operations, as well as a wide range , can be created using more common drawing and bending operations . Has limited weldability and dynamic or shock loaded steel structures used as the source case . 430 is a ferritic material shows brittle fracture at temperatures below zero and can not be used in cryogenic applications . Steel , nickel or molybdenum does not involve , 300 series stainless steels are less expensive.
Applications: Industrial roofing and wall coverings, kitchen utensils , sink , washing machine parts and automotive trim , such as industrial and architectural applications
Corrosion Resistance : Some are based on the oxidation of acidic and salty water . Moderate .
