Cross Reference Table(Equivalent Grade)
GradeStandardCountryApplication
A-2AISIUSA
Applied to the thermosetting plastic mold, the hardened mould as a whole
Y1Cr18Ni9AISIUSA
Improve the machinability, ablation resistance. Suitable for automatic lathe production of bolt and nut
1Cr18Ni9AISIUSA
High strength after cold forming, but elongation than 1 cr17ni7 slightly worse. Used in architectural decoration parts
1Cr18Mn10Ni5Mo3NAISIUSA
Of urea with good corrosion resistance, can produce urea corrosion of the equipment.
1Cr17Ni7AISIUSA
High strength after cold forming. Used in railway vehicle, conveyor belt, bolt and nut, etc
Y1Cr18Ni9SeAISIUSA
Improve the machinability, ablation resistance. Suitable for automatic lathe production of rivets, screws
0Cr18Ni9AISIUSA
Seamless stainless steel tubes for boiler and heat exchanger
00Cr19Ni10AISIUSA
Carbon content lower than 0Cr19ni9 steel, excellent intergranular corrosion resistance, is used for welding after the class is not processed parts
1Cr17Mn6Ni5NAISIUSA
Nickel steel grade, instead of number 1 cr17ni7 and magnetism after cold working, used in railway vehicle, etc
1Cr18Mn8Ni5NAISIUSA
Nickel steel, instead of 1cr18ni9
0Cr19Ni9NAISIUSA
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
0Cr19Ni10NbNAISIUSA
Based on zero cr19ni9 plus N and Nb, with better than 0 cr19ni9 properties and USES
00Cr18Ni10NAISIUSA
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
1Cr18Ni12AISIUSA
Compared with 0 cr19ni9, processing low hardenability. Used for spinning processing, special drawing, cold heading
0Cr23Ni13AISIUSA
Corrosion resistance and heat resistance are better than 0cr19ni9
0Cr25Ni20AISIUSA
Oxidation resistance is better than 0cr23ni13. Mostly used as heat resistant steel
0Cr17Ni12Mo2AISIUSA
Seamless stainless steel tubes for boiler and heat exchanger
1Cr18Ni12Mo2TiAISIUSA
Seamless stainless steel tubes for boiler and heat exchanger
0Cr18Ni12Mo2TiAISIUSA
Seamless stainless steel tubes for boiler and heat exchanger
A-29 1025AISIUSA
General use carbon steel rod
