321H is mainly used in the chemical, coal and petroleum industry with high requirements of grain boundary corrosion resistance of outdoor machines, building materials heat resistant parts and parts with difficulties in heat treatment, such as oil exhaust gas combustion pipeline;engine exhaust pipe;boiler shell, heat exchanger, heating furnace components;silencing components for diesel engines;boiler pressure vessel;chemical transport vehicle;expansion joint;spiral welded pipes for furnace pipes and dryers.

347 stainless steel in 400 ~ 900℃ temperature range of high temperature corrosion and oxidation resistance, can be used for the working temperature below 850℃ pipe fittings, widely used in petrochemical, food, paper and thermal power plant, nuclear power industry in the large boiler superheater, reheater, steam pipe, shaft parts, welding structural parts.

347 stainless steel welding performance is good, but also commonly used for welding core and welding tape and other welding materials.

347H stainless steel has good corrosion resistance, welding performance and thermal strength.Used in large boiler superheater, reheater, steam pipe, petrochemical heat exchanger pipe fittings.

405 stainless steel is mainly used in the manufacture of toughness and impact load parts, such as turbine blades, rate exergy parts (quenching bench), annealing box, composite steel, stainless equipment, lining, etc.

409 stainless steel is commonly used in machinery, construction and other engineering ferritic stainless steel.Due to the existence of austenite grains, its mechanical properties are greatly improved.And because of the addition of a lot of alloy elements, the strength and hardness has been greatly improved.

410L stainless steel has low carbon content, its corrosion resistance, toughness and weldability with the increase of chromium content, chloride stress corrosion resistance performance is better than other kinds of stainless steel.Good bending performance, machining performance and high temperature oxidation resistance of welding parts.
