Cross Reference Table(Equivalent Grade)
Grade Standard Country Application
Y1Cr18Ni9 SS UK
Improve the machinability, ablation resistance. Suitable for automatic lathe production of bolt and nut
1Cr18Ni9 SS UK
High strength after cold forming, but elongation than 1 cr17ni7 slightly worse. Used in architectural decoration parts
1Cr18Mn10Ni5Mo3N SS UK
Of urea with good corrosion resistance, can produce urea corrosion of the equipment.
1Cr17Ni7 SS UK
High strength after cold forming. Used in railway vehicle, conveyor belt, bolt and nut, etc
Y1Cr18Ni9Se SS UK
Improve the machinability, ablation resistance. Suitable for automatic lathe production of rivets, screws
0Cr18Ni9 SS UK
Seamless stainless steel tubes for boiler and heat exchanger
00Cr19Ni10 SS UK
Carbon content lower than 0Cr19ni9 steel, excellent intergranular corrosion resistance, is used for welding after the class is not processed parts
1Cr17Mn6Ni5N SS UK
Nickel steel grade, instead of number 1 cr17ni7 and magnetism after cold working, used in railway vehicle, etc
1Cr18Mn8Ni5N SS UK
Nickel steel, instead of 1cr18ni9
0Cr19Ni9N SS UK
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
0Cr19Ni10NbN SS UK
Based on zero cr19ni9 plus N and Nb, with better than 0 cr19ni9 properties and USES
00Cr18Ni10N SS UK
In 00cr19ni10 adding N, on the basis of the above grades also features, use the same as the 0 cr19ni9n, but better intergranular corrosion resistance
1Cr18Ni12 SS UK
Compared with 0 cr19ni9, processing low hardenability. Used for spinning processing, special drawing, cold heading
0Cr23Ni13 SS UK
Corrosion resistance and heat resistance are better than 0cr19ni9
0Cr25Ni20 SS UK
Oxidation resistance is better than 0cr23ni13. Mostly used as heat resistant steel
0Cr17Ni12Mo2 SS UK
Seamless stainless steel tubes for boiler and heat exchanger
1Cr18Ni12Mo2Ti SS UK
Seamless stainless steel tubes for boiler and heat exchanger
0Cr18Ni12Mo2Ti SS UK
Seamless stainless steel tubes for boiler and heat exchanger
A-29 1025 SS UK
General use carbon steel rod
1025 SS UK
These products have been used typically for use in fabrication of fittings, but usage is not limited to such applications. These products are not typically used for deep forming or cupping operations.
