Stainless steel material properties and applications

Austenitic stainless steel category feature USES AUSTENITE301 0 gr17ni7gr, Ni content is lower than 304, the tensile strength and hardness by cold rolling, cold rolling processing after a certain magnetism. Train, aircraft, vehicles, spring 304 0 gr18ni9 the most commonly used types of steel. The corrosion resistance, heat resistance, low temperature strength, good mechanical properties. Deep drawing, bending and normal temperature processing performance is good. Do not produce hardening after heat treatment. ( No magnetic, using temperature: - 196 - 800℃) Household utensils, sinks, indoor plumbing, water heater, bath crock, boiler, automobile spare parts ( Wiper, wash the sound device, mould) , medical equipment, food machinery, chemical equipment, building materials, etc. 304 l 00 gr18ni9 for low carbon steel 304. The corrosion resistance in normal state in 304. But after welding or remove stress after good resistance to intergranular corrosion. After processing without annealing remains corrosion resistance, generally used under 400 * C ( No magnetic, using temperature: - 196 - 800℃) Intergranular corrosion resistant high performance requirements of chemical industry, coal, oil machinery, building materials, heat resistant parts and parts heat treatment difficult 316 00 gr18ni12mo2 low carbon steel, 316 l printing added Mo, its corrosion resistance, resistance to pitting corrosion, intergranular corrosion resistant ability is good. Good resistance to high temperature strength, use in harsh environment. Good work hardening. Water equipment, chemical, papermaking, dyes, acetic acid, fertilizer production equipment, facilities, food industry, coastal areas and other products are in great need of intergranular corrosion resistant effect of 321 1 gr18ni9ti add Ti on 304 steel, to prevent intergranular corrosion, suitable for use in the 430 - 900 * C environment air mechanical ferritic stainless steel pipe, boiler cover FERRITE409L 00 gr12ti low-carbon steel 409, good weldability and workability auto exhaust pipe, heat exchanger, the container does not need to heat treatment after welding of 410 l 00 gr13 good mechanical structure with high temperature oxidation resistance, engine exhaust pipe, boiler combustion device 430 1 gr17 ferritic steel on behalf of the steel. Low thermal expansion rate, forming, good oxidation resistance to heat stove, oven, home appliance parts, 2 kinds of tableware, water tank, decoration, screw nut
