• 430 is a low-carbon chromium ferritic stainless steel. This steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. In the annealed condition the steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch- bending operations.
• 430 has limited weldability and should not be used in the as-welded condition for dynamic or impact loaded structures. Being a ferritic material, 430 has the potential to suffer brittle fracture at sub-zero temperatures. It should not be used in cryogenic applications.

Typical Applications
430 is a simple corrosion and heat-resisting grade and finds application in areas where mildly corrosive conditions occur or where scaling resistance at moderate temperatures is required.
Typical applications include:
• Automotive trim, architectural applications such as industrial roofing and wall cladding.
• Kitchen and cafeteria utensils and cutlery, sinks, wash troughs, urinals, toilets, trim for domestic equipment.

General corrosion resistance
430 stainless steel has good resistance to a wide variety of corrosive environments including nitric acid and some organic acids. It is generally used for highly polished applications and in mild atmospheres such as for food processing and dairy equipment. Atmospheric corrosion resistance is good, although in highly polluted or marine environments staining may occur.
Cold rolled
Standard ferritic stainless steels have fair formability characteristics with useful mechanical properties. Their ductility allows them to be formed by bending and deep drawing. They do not undergo significant work hardening when cold formed.
Welding
The standard ferritic stainless steels are prone to grain growth in the heat-affected zone. As such, the tensile, fatigue and toughness properties in the welded condition are relatively poor. They should thus not be used for applications where tensile or dynamic loading will be experienced.
