316L is a stainless steel grade, AISI 316L is the corresponding US label, SUS316L is the corresponding Japanese label. China's standard grade 022Cr17Ni12Mo2 (new standard), the old grade 00Cr17Ni14Mo2.
Due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in harsh conditions; processing hardening excellent (non-magnetic). As a low-C series of 316 steel grades, in addition to the same characteristics with 316 steel, its excellent resistance to grain boundary corrosion. Its excellent performance has been widely used in high-level watch bracelet, case and so on.
