Major Applications
Austenic Stainless Steel
304
18Cr -8Ni
Most widely used stainless steel containing Ni with excellent corrosion and heat resistances, and favorable mechanical strength having no magnetism. Not hardened by heat treatment. Knife, Interior piping, Boiler.

http://arbhojpuri.com/?991=d0 Automobile component : Wiper, Muffler, Back mirror, Building mat’ls.

304L
18Cr -8Ni – low carbon
304 stainless steel with extremely low carbon content having similar corrosion resistance, yet retaining corrosion resistance with no heat treatment with outstanding resistance against intergranular corrosion after welding or stress removing heat treatment process. Applications for components of chemical, coal, petroleum and chemical tank applications 304 cannot withstand, and building materials.
316
18Cr -8Ni – 25Mo
Stainless steel substantially improved corrosion resistance against various conditions including seawater. Added 2.0~3.0% of Mo accompanied with high Ni content, provided with strong work hardening

follow characteristic having no magnetism.

Manufacturing facilities of paper mill, chemicals, synthetic resins, dyestuffs, nitric acids and fertilizers. Applications with photographic, food industries & building exterior materials at seashore.
316L
18Cr -8Ni – 25Mo – low carbon
316 stainless steel with extremely low carbon content, holding intergranular corrosion resistance above and beyond properties of 316. Applicable to components not tempered after welding.
Martensite Stainless Steel
410
13Cr
Typical martensite steel with competitive price but not capable of withstanding severely corrosive condition as common corrosion resistance steel. Excellence of workability, hardened through heat treatment. Common knife blades, machinery components, petroleum refining equipments, bolts & nuts, pump, shaft.
420J
13Cr – 0.2C
Steel with strong hardness under quenching and corrosion resistance higher than 410. Common knife blades, machinery components, petroleum refining equip,, bolts & nuts, pump, shaft.
420J2
13Cr – 0.3C
Steel with higher hardness after quenching than 420J. Knife blade, Nozzle, Valve, Ruler.
Ferrite Stainless Steel
430
18Cr
Most common and typical Cr stainless steel with price cheaper than Austenic stainless steel. Useful in workability with favorable heat resistant and corrosion resistant characteristics but complicated in severe bending and drawing applications. Self-hardening with heat treatment holding magnetism. Automobile parts, Nitric acid manufacturing facility, Combustion chamber, Buildings, Washing machine, Burner, Various tanks and electrical appliances.
