Characteristics and uses of stainless steel:

Character and use of serial number category

1 austenite shape 1Cr17Mn6Ni5N nickel steel, replacing the brand 1Cr17Ni7, after cold processing has magnetic. Railway vehicles.

2 1Cr18Mn8Ni5N section nickel steel, instead of brand 1Cr18Ni9

3 1Cr17Ni7 has high strength by cold processing. Railway vehicles, conveyor belts, bolts and nuts

4 1Cr18Ni9 has high strength by cold processing, but its elongation is slightly worse than that of 1Cr17Ni7. Decorative parts for buildings.

5 Y1Cr18Ni9 improves cutting and ablative resistance. It is most suitable for automatic lathe. Bolt and nut

6 Y1Cr18Ni9Se improves cutting and ablative resistance. It is most suitable for automatic lathe. Rivets and screws

7 0Cr19Ni9 is the most widely used as a heat-resistant steel, food equipment, general chemical equipment, atomic energy industry

8 00Cr19Ni11 steel with lower carbon content than 0Cr19Ni9 has superior intercrystalline corrosion resistance and does not carry out heat treatment components after welding.

9 0Cr19Ni9N added N on the brand 0Cr19Ni9, the strength increased, and the plasticity was not reduced. The thickness of the material is reduced. As a structural strength component 10 0Cr19Ni10NbN, N and Nb are added to the brand 0Cr19Ni9, and have the same characteristics and uses as 0Cr19Ni9N.

11 00Cr18Ni10N added N on the brand 00Cr19Ni11, with the same brand as the same characteristic, the same as 0Cr19Ni9N, but better intercrystalline corrosion resistance

12 1Cr18Ni12, compared with 0Cr19Ni9, is hardened. Spinning, special drawing, cold heading 13 0Cr23Ni13 corrosion resistance, heat resistance is better than 0Cr19Ni9 14 0Cr25Ni20 to do a better oxidation than 0Cr23Ni13. In fact, it is used as a heat-resistant steel.

15 0Cr17Ni12Mo2 has better corrosion resistance than 0Cr19Ni9 in sea water and various other media. Main corrosion resistant material

16 0Cr18Ni12Mo2Ti for resistance to sulfuric acid phosphoric acid, formic acid, acetic acid, equipment, have good resistance to intergranular corrosion

17 00Cr17Ni14Mo2 is 0Cr17Ni12Mo2 ultra low carbon steel, which has better intercrystalline corrosion resistance than 0Cr17Ni12Mo2

18 0Cr17Ni12Mo2N added N in the brand 0Cr17Ni12Mo2 to improve the strength without reducing the plasticity and reducing the thickness of the material. A component with better corrosion resistance

19 00Cr17Ni13Mo2N added N in the brand 00Cr17Ni14Mo2, with the same brand as the same characteristic, the same as 0Cr17Ni12Mo2, but better corrosion resistance.

The corrosion resistance and point corrosion resistance of 20 0Cr18Ni12Mo2Cu2 are better than that of 0Cr17Ni12Mo2. Used in sulphuric acid resistant materials

21 00Cr18Ni14Mo2Cu2 is 0Cr18Ni12Mo2Cu2 ultra low carbon steel, which has better intercrystalline corrosion resistance than 0Cr18Ni12Mo2Cu2

The corrosion resistance of 22 0C19Ni13Mo3 is better than that of 0Cr17Ni12Mo2.  As a material for dyeing equipment, etc.

23 00Cr19Ni13Mo3 is 0Cr19Ni13Mo3 ultra low carbon steel, which has better intercrystalline corrosion resistance than 0Cr19Ni13Mo3

24, 0Cr18Ni16Mo5 absorbs heat exchangers containing chlorine ion solution, acetic acid equipment, phosphoric acid equipment, bleaching device and so on. It is used in environments where 00Cr17Ni14Mo2 and 00Cr17Ni13Mo3 can not be applied.

25 1Cr18Ni9Ti welding Bai, instrumentation, medical equipment, diamagnetic acid containers and equipment lining pipeline equipment and spare parts etc.

Adding Ti to 26 0Cr18Ni11Ti increases intercrystalline corrosion resistance and is not recommended as an ornamental component

Increase the intercrystalline corrosion resistance of 27 0Cr18Ni11Nb containing Nb
