Product Introduction：
316 316L steel is following the 304 stainless steel after the second most widely used. The only difference between them is the carbon content. This leads to a little difference between the two, but the overall use is the same.About 316 material:316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions.Corrosion resistance is better than 304 stainless steel, in pulp and paper production process has good corrosion resistance. And 316 stainless steel is also resistant to erosion of marine and corrosive industrial atmosphere.
About 316L material:316L stainless steel has a carbon content of less than 316, which is commonly used in pulp and paper equipment heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal areas outside the building materials. Corrosion resistance is better than 316 material.

Applications
316 and 316L stainless steel is widely used in pulp and paper equipment heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal areas outside the building materials, marine, industrial air field.Also used in the field of solenoid valve, mainly used in the shell, clamp, ball, valve body, valve seat, nut, stem and so on.
316L stainless steel also has good resistance to chloride corrosion, so it is often used in marine environment.What’s more,with good welding performance, can use all standard welding method for welding.
Different Production Standards
Grade （材质） | GB/T 1220-2007 （国标） | ASTM （美标） | DIN （欧标） | JIS （日标） | KS （韩国） |
316 | 06Cr17Ni12Mo2 | 316 | 1.4401 | SUS316 | STS316 |
316L | 022Cr17Ni12Mo | 316L | 1.4404 | SUS316L | STS316L |
The advantage of 316/316L material
1 cold rolling product appearance gloss good, beautiful;
2) due to the addition of Mo, corrosion resistance, especially pitting corrosion resistance;
3) high temperature strength
4) excellent work hardening (weak magnetic processing)
5) solid solution state;
6) relative to 304 stainless steel, higher prices.But with better physical property and chemical composition.
