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
1Cr18Mn10Ni5Mo3N Of urea with good corrosion resistance, can produce urea corrosion of the equipment.
1Cr17Ni7 High strength after cold forming. Used in railway vehicle, conveyor belt, bolt and nut, etc
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
1Cr17Mn6Ni5N Nickel steel grade, instead of number 1 cr17ni7 and magnetism after cold working, used in railway vehicle, etc
1Cr18Mn8Ni5N Nickel steel, instead of 1cr18ni9
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
0Cr19Ni10NbN Based on zero cr19ni9 plus N and Nb, with better than 0 cr19ni9 properties and USES
00Cr18Ni10N 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 Compared with 0 cr19ni9, processing low hardenability. Used for spinning processing, special drawing, cold heading
0Cr23Ni13 Corrosion resistance and heat resistance are better than 0cr19ni9
0Cr25Ni20 Oxidation resistance is better than 0cr23ni13. Mostly used as heat resistant steel
0Cr17Ni12Mo2 Seamless stainless steel tubes for boiler and heat exchanger
1Cr18Ni12Mo2Ti Seamless stainless steel tubes for boiler and heat exchanger
0Cr18Ni12Mo2Ti Seamless stainless steel tubes for boiler and heat exchanger
A-29 1025 General use carbon steel rod
1025 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.
