Stainless Steel Sheet – Cold Rolled
304 Stainless Steel Sheet
304 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.
316 Stainless Steel Sheet
316 is an improved version of 304 due to the addition of molybdenum and a slightly higher nickel content. The resultant composition of 316 gives the steel improved corrosion resistance in many aggressive environments. The molybdenum makes the steel more resistant to pitting and crevice corrosion in chloride-contaminated media, seawater and to acetic acid vapours. The lower rate of general corrosion in mildly corrosive environments gives the steel good atmospheric corrosion resistance in polluted marine atmospheres.
430 Stainless Steel Sheet
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.
409 Stainless Steel Sheet
409 is a 12% chromium, titanium stabilised ferritic stainless steel. It has fair resistance to corrosion and oxidation at high temperatures. In the annealed condition 409 is ductile, does not work harden and can be formed using a variety of roll forming, bending or mild pressing/ stamping operations. 409 is resistant to stress corrosion cracking but has limited weldablity. 409 should not be used in the as-welded condition for dynamic or impact loaded structures.
3CR12 Stainless Steel Sheet
South African developed 3CR12 is recognised as the original chromium utility ferritic stainless steel. 3CR12 was developed as an alternative material where the mechanical properties, corrosion resistance and fabrication requirements of other materials such as mild steel, galvanised, aluminium, or pre-painted steels are unsuitable. 3CR12 is a corrosion resisting steel and, as such, will exhibit staining when exposed to aggressive atmospheric conditions. In applications where aesthetic appearance is important, it is recommended that the 3CR12 be painted or that a stainless steel such as 304 be used.
441 Stainless Steel Sheet / 1.4509
1.4509 is a low carbon, dual stabilised (titanium and niobium) ferritic stainless steel containing 18% chromium. It has good corrosion resistance in moderately corrosive environments and good oxidization and creep resistance at elevated temperatures. In the annealed condition 1.4509 is ductile, does not work harden and can be formed using a variety of roll forming, bending or mild pressing/ stamping operations. 1.4509 is resistant to stress corrosion cracking but has limited weldablity. 1.4509 should not be used in the as-welded condition for dynamic or impact loaded structures.
