应用

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.
