General Introduction of 316L stainless steel:
316L is a Grade of stainless steel material. AISI 316L is the corresponding American label, and SUS 316L is the corresponding Japanese label. Mainly contains Cr, Ni, Mo, figures indicate approximately the percentage. 316L stainless steel used in the pulp and papermaking equipment heat exchanger, dyeing equipment, film materials for external equipment, pipelines, coastal areas of the building and flushing, senior watch chain, case etc.. Equipment, chemicals, dyes, paper making, oxalic acid, fertilizer, etc.; equipment for photography, food industry, coastal areas, ropes, CD poles, bolts, nuts, etc.
1.About 316:
-Corrosion resistance
Better corrosion resistance than 304 stainless steel, in the pulp and paper production process, has good corrosion resistance. Also, 316 stainless steel is also resistant to erosion by oceanic and corrosive industrial atmospheres.
-Heat resistance
316 stainless steel (06Cr17Ni12Mo2) has excellent oxidation resistance in discontinuous use at 871 degrees C (1600 degrees F) and for continuous use at 927C degrees (1700 degrees F). At 427 degrees C-857 degrees C (800 degrees F-1575 degrees F) range, it is best not to continue to use 316 stainless steel, but in the temperature range other than the continuous use of 316 stainless steel, the stainless steel has good heat resistance. 316L stainless steel has better carbide precipitation resistance than 316 stainless steel, and can be used in the above range of temperature.
