What are the commonly used stainless steel grades?
Commonly used stainless steel grades include the following:
Grade | Features | Applications |
304 | Most commonly used, with good corrosion resistance and formability | Kitchen equipment, chemical containers, |
316 | Contains molybdenum to enhance corrosion resistance, especially suitable for marine and chemical environments | Marine facilities, chemical equipment, |
430 | Martensitic stainless steel, low corrosion resistance,cheap price, good formability | Household appliances, decorative materials |
201 | Low-cost alternative to 304, low nickel content, weak corrosion resistance | Kitchen equipment, tableware, pipes |
410 | High carbon content, high strength, good wear resistance, relatively poor corrosion resistance | Knives, tableware, valves |
310S | High nickel, high chromium, extremely high oxidation resistance and high temperature resistance | High temperature furnaces, petrochemical |
904L | Ultra-low carbon high alloy austenitic stainless steel,excellent corrosion resistance | Petrochemical equipment, acidic environment |
321 | Adding titanium to 304, enhanced resistance to intergranular corrosion | Aerospace, chemical, boiler parts |
Each of these grades has its own unique performance and application areas, and the selection should be based on the specific use environment and requirements.
