Complete list of 11 stainless steel models

[ Data:2023-11-28 View:1Times ]

1. Model 301 - has good ductility and is suitable for the manufacture of molded products. In addition, it can be quickly hardened by machining. At the same time, the welding performance of this model is also very good. In terms of wear resistance and fatigue strength, it is superior to 304 stainless steel.

2. Model 302 - Its corrosion resistance is the same as 304, but its strength is better due to the relatively high carbon content.

3. Model 303 - By adding a small amount of sulfur and phosphorus, it makes it easier to cut than 304.

4. Model 304 - This is a general purpose model, i.e. 18/8 stainless steel. In the Chinese national standard (GB), its brand number is 0Cr18Ni9.

5. Model 309 - Compared to 304, it has better temperature resistance.

6. Model 316 - After 304, this is the second widely used steel grade, mainly used in the food industry and the production of surgical equipment. By adding molybdenum, it obtains a special structure that is resistant to corrosion. Because its resistance to chloride corrosion is better than 304, it is also known as "Marine steel".

7. Model 321 - Similar in performance to 304 except for the addition of titanium which reduces the risk of corrosion in the weld of the material.

8. Model 408 - has good heat resistance, but weak corrosion resistance. It contains 11% chromium and 8% nickel.

9. Model 409 - This is the cheapest model (Anglo-American), which is usually used to make automobile exhaust pipes and belongs to ferritic stainless steel (chromium steel).

10. Model 410 - This is a martensite (high strength chromium steel), good wear resistance, but poor corrosion resistance.

11. Model 416 - Improved processing properties of the material by adding sulfur.
