Cross Reference Table(Equivalent Grade)
Grade	Standard	Country	Application
Y1Cr18Ni9			Improve the machinability, ablation resistance. Suitable for automatic lathe production of bolt and nut
1Cr18Ni9			High strength after cold forming, but elongation than 1 cr17ni7 slightly worse. Used in architectural decoration parts
Y1Cr18Ni9Se			Improve the machinability, ablation resistance. Suitable for automatic lathe production of rivets, screws
0Cr18Ni9			Seamless stainless steel tubes for boiler and heat exchanger
00Cr19Ni10			Carbon content lower than 0Cr19ni9 steel, excellent intergranular corrosion resistance, is used for welding after the class is not processed parts
0Cr19Ni9N			Based on 0cr19ni9 plus N, strength increase and the plastic is not down. Reduce the thickness of the material. As a structure with strength components
