ss 304 coil

• 304 stainless steel is the most versatile and widely used of all stainless steels. Its chemical composition, mechanical properties, weldability and corrosion/oxidation resistance provide the best all-round performance stainless steel at relatively low cost. It also has excellent low-temperature properties and responds well to hardening by cold working. If the potential for intergranular corrosion in the heat-affected zone exists, 304L is recommended.

• 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.
