301 stainless steel pipe

301 stainless steel is a metastable austenitic stainless steel with a complete austenite structure formed after full dissolution. 301 is the easiest type of stainless steel to be strengthened by cold deformation. After cold deformation treatment, the strength and hardness of the steel can be improved while maintaining sufficient plasticity and toughness. In addition, the rust resistance of this steel in the air is also improved. Very good, but its corrosion resistance is very poor in reducing media, and its corrosion resistance is relatively poor in acid, alkali, salt and other chemical media. Therefore, it is not recommended to be used in severely corrosive environments. . 301 is a part that is mainly used to carry high loads and requires lightweight equipment and anti-corrosion.

National implementation standards of 301 stainless steel:

1. Chinese standard GB-T standard: digital grade: S30110, new grade: 12Cr17Ni7, old grade: 1Cr17Ni7

2. American standards: ASTMA standard: 301, SAE standard: 30301, UNS standard: S30100

3. Japanese standard JIS standard: SUS301

4. German DIN standard: 1.4319, 5. European EN standard: X5CrNi17-7, X3CrNi17-8.
