General Properties Grade 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application. Applications Typical applications for 430 grade include: Linings for dish washers Refrigerator cabinet panels Automotive trim Lashing Wire Element Supports Stove trim rings Fasteners Chimney Liners 430 stainless steel chemical composition Grade C Si Mn Cr N P S Ni 430 ≤0.12 ≤0.75 ≤1.00 16.00~18.00 - ≤0.040 ≤0.03 ≤0.60 430 physical properties 430 Density : 7.75g/cm3 Melting point： 1427℃ Tensile Strength: σb (MPa)≥450 Yield strength : σ0.2 (MPa)≥205 Corrosion Resistance Grade 430 has good resistance to a wide variety of corrosive enviornments, including nitric acid and some organic acids. It attains its maximum corrosion resistance when in the highly polished or buffed condition. In general its resistance to pitting and crevice corrosion resistance is close to that of grade 304. Stress corrosion cracking resistance of Grade 430 is very high, as it is for all ferritic grades. Heat Resistance Grade 430 resists oxidation in intermittent service up to 870°C and to 815°C in continuous service. This grade may become brittle at room temperature after prolonged heating in the 400-600°C range. This effect can be eliminated by annealing.
