Note: 1. ASTM standard quality level of carbon steel rod can see ASTM cold A108-1999, its GangHao the chemical composition of the same with this form.
2. ASTM special levels of quality carbon steel rod can see the hot working ASTM A576 (90 b) (2000), the GangHao the chemical composition of the same with this form.
3. Require Si content (mass fraction), usually in the following 4 files a choice: 0.10% or Si, Si 0.10 ~ 0.20%, Si 0.20 ~ 0.40%, Si 0.30 ~ 0.60%.
4. Require Cu content (quality score) is 0.20% or Cu.

Cross Reference Table(Equivalent Grade)
GradeStandardCountryApplication
Y1Cr18Ni9ASTMUSA
Improve the machinability, ablation resistance. Suitable for automatic lathe production of bolt and nut
1Cr18Ni9ASTMUSA
High strength after cold forming, but elongation than 1 cr17ni7 slightly worse. Used in architectural decoration parts
1Cr18Mn10Ni5Mo3NASTMUSA
Of urea with good corrosion resistance, can produce urea corrosion of the equipment.
1Cr17Ni7ASTMUSA
High strength after cold forming. Used in railway vehicle, conveyor belt, bolt and nut, etc
Y1Cr18Ni9SeASTMUSA
Improve the machinability, ablation resistance. Suitable for automatic lathe production of rivets, screws
0Cr18Ni9ASTMUSA
Seamless stainless steel tubes for boiler and heat exchanger
00Cr19Ni10ASTMUSA
Carbon content lower than 0Cr19ni9 steel, excellent intergranular corrosion resistance, is used for welding after the class is not processed parts
1Cr17Mn6Ni5NASTMUSA
Nickel steel grade, instead of number 1 cr17ni7 and magnetism after cold working, used in railway vehicle, etc
1Cr18Mn8Ni5NASTMUSA
Nickel steel, instead of 1cr18ni9
0Cr19Ni9NASTMUSA
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
0Cr19Ni10NbNASTMUSA
Based on zero cr19ni9 plus N and Nb, with better than 0 cr19ni9 properties and USES
00Cr18Ni10NASTMUSA
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
1Cr18Ni12ASTMUSA
Compared with 0 cr19ni9, processing low hardenability. Used for spinning processing, special drawing, cold heading
0Cr23Ni13ASTMUSA
Corrosion resistance and heat resistance are better than 0cr19ni9
0Cr25Ni20ASTMUSA
Oxidation resistance is better than 0cr23ni13. Mostly used as heat resistant steel
0Cr17Ni12Mo2ASTMUSA
Seamless stainless steel tubes for boiler and heat exchanger
1Cr18Ni12Mo2TiASTMUSA
Seamless stainless steel tubes for boiler and heat exchanger
0Cr18Ni12Mo2TiASTMUSA
Seamless stainless steel tubes for boiler and heat exchanger
A-29 1025ASTMUSA
General use carbon steel rod
1025ASTMUSA
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.
