316l stainless steel product introduction
316l China GB old grade 00Cr17Ni14Mo2, China GB new grade 022Cr17Ni12Mo2, new grade unified digital code S31603, American UNS standard grade S31603, Taiwan CNS standard grade 316L, Japan JIS standard grade SUS316L.
Most of the existing 316L on the market are produced according to American Standard. Due to cost concerns, steel mills should lower the Ni content of their products to an appropriate lower limit. According to the American standard regulations, the Ni content of 316L is 10-14%, and the Japanese standard regulations, the Ni content of 316L is 12-15%. According to the minimum, there is a 2% difference between the American standard and the Japanese standard in Ni content, which is still quite huge in terms of price, so customers still need to see clearly when purchasing 316L products, whether the products refer to ASTM or JIS standards.
SUS316L Japanese SUS series stainless steel has lower carbon content than 316 steel and better resistance to intergranular corrosion. It is suitable for use as important corrosion-resistant materials in chemical, chemical fiber, fertilizer and other industries. In addition to the characteristics of atmospheric corrosion resistance and high temperature strength, and can be used under harsh conditions, its resistance to intergranular corrosion is excellent, and its work hardening is excellent, seawater equipment, papermaking and other production equipment, acetic acid equipment. Its resistance to intergranular corrosion Good. The maximum carbon content of 316L stainless steel is 0.03, which can be used in applications that cannot be annealed after welding and must have maximum corrosion resistance.
316l stainless steel has low carbon content and 2℅~3℅ molybdenum, which improves the corrosion resistance of reducing salts and various inorganic acids and organic acids, alkalis and salts, and at the same time high temperature strength.

316l stainless steel performance advantages
1) The appearance of cold-rolled products has good gloss and beautiful appearance;
2) Due to the addition of Mo, the corrosion resistance, especially the pitting resistance, is excellent;
3) Excellent high temperature strength;
4) Excellent work hardening (weak magnetic properties after processing);
5) Non-magnetic in solid solution state.
