Product description
SS430 is a low-carbon plain chromium,ferritic stainless steel without any stabilization of carbon and nitrogen with titanium or niobium.With 16% chromium,the steel has good crrosion resistance in soft corrosive environments and good oxidation resistance at elevator temperatures.Annealed SS430 is ductile and can be formed using a large variety of roll forming or mild stretch-bending operations as well as the more common drawing and bending operations.
SS430 has limited weldability and should not be used in the as-welded condition for dynamic or impact loaded structures.SS430 can form martensite in the heat affected zone of weldments,which may adversely affect the mechanical properties an these zones.Applications involving welded SS430 are generally limited to a maximum thickness of 3mm.
Corrosion Resistance:
SS430 has good corrosion resistance in a wide varitely 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.
Annealing:
Annealing is achieved by heating to above 760℃ and 830℃for 90 minutes per 25mm thickness followed by air quenching.Controlled atmospheres are recommended in order to avoid excessive oxidation of the surface.
Welding:
SS430 is prone to brittle characteristic in the heat-affected zone of weldments due to formation of martensitic phase.Thw tensile,fatigue and thoughness properties in the welded condition are relatively poor.So SS430 should not be used for applications where tensile or dynamic loading will be experience.Edge welds are not recommended for SS430.The use of austenitic filler metals such as types 309S or 316L will improve the ductility of welds to some extent but all welding procedures should nevertheless endeavor to maintain minimum heat inputs.The weld discoloration should be removed by pickling and p[assivating to restore maximum corrosion resistance.
