Characteristic


Usage

300

304

As a widely used steel, it has good   corrosion resistance, heat resistance, low temperature strength and   mechanical properties. And good hot workability such as stamping and bending,   no heat treatment hardening (non-magnetic, use temperature -196 ° C ~ 800 °   C).

Food industry, household goods (tableware,   kitchen cabinets, indoor pipelines, water heaters, boilers, bathtubs)

304L

As a low-carbon 304 steel, its corrosion   resistance is similar to that of 304 steel under normal conditions, but its   resistance to intergranular corrosion is excellent after welding or after   stress relief. It can maintain good corrosion resistance without heat   treatment, generally used below 400 (non-magnetic, use temperature -196 ° C ~   800 ° C).

Used in field open-air machines, building   materials, heat-resistant parts and parts with difficult heat treatment in   the chemical, coal and petroleum industries with high resistance to   intergranular corrosion.

321

Ti element is added to 304 steel to   prevent grain boundary corrosion. Suitable for use at temperatures from 430 °   C to 900 ° C.

Medical equipment, building materials,   chemicals, agriculture, marine components, atomic energy industry, aircraft,   piping, boiler steam drum auto parts (windshield wipers,  molded products)

316

Mo should be added, so its corrosion resistance,   atmospheric corrosion resistance and high temperature strength are   particularly good, and it can be used under severe conditions with excellent   work hardening (non-magnetic).

Equipment, chemicals, dyes, and   papermaking in seawater. Production equipment such as oxalic acid and   fertilizer; photo, food industry, coastal facilities, ropes, CD rods, bolts,   nuts

316L

As a low carbon series of 316 steel, it   has excellent resistance to intergranular corrosion in addition to the same   characteristics as 316 steel.

Products for fear of grain boundary   corrosion in 316 steel applications

309S

23Cr-13Ni high alloy steel stainless   steel, with excellent corrosion resistance and strength, is suitable for   parts with working temperature of 1000 °C.

Exhaust machines, heat treatment furnaces   and heat exchangers, etc.

310S

It has very good oxidation resistance,   corrosion resistance, high temperature resistance, because of the higher   percentage of chromium and nickel, 310S has much better creep strength, it can   continue to work at high temperatures, and has good high temperature   resistance.

Boilers, exhaust machines, heat treatment   furnaces and heat exchangers, etc.
