Drawing diagram (Unit:mm)
|304-A2||0.1||1||2||0.05||0.003||15-20||8-19||4||Medium work hardening rate, suitable for general cold working and drawing, good cold working performance, commonly used for hexagon socket screws, nuts and washers |
Molybdenum added corrosion resistance is stronger than 304, especially suitable for seawater and chemical media, more corrosion resistance and pitting resistance.
1. If the nickel content is less than 8%, the minimum content of manganese must be 5%.
2. When the nickel content is more than 8%, the minimum content of copper is not limited.
3. If the chromium content is less than 17%, the minimum content of nickel is 12%.
4. For austenitic stainless steels with a maximum carbon content of 0.03%, the nitrogen content can reach up
5. For larger diameter products, in order to achieve the specified mechanical properties, there may be a higher
carbon content in the manufacturer's instructions, but not more than 0.12% for martensitic steel
1. Why is stainless steel also magnetic?
304 stainless steel is an austenitic stainless steel. Austenite is partially or slightly converted to martensitic during cold working, and martensitic is magnetic, so 304 stainless steel is non-magnetic or micro-magnetic
2. How to correctly identify 304 stainless steel products？
① Support 304 stainless steel special detection syrup detection, If it is not discolored, it is
304 stainless steel
② Support for chemical composition analysis and spectral analysis③ Support salt spray test to simulate the actual use environment.
3. What kinds of stainless steel are commonly used?
① 201 stainless steel, suitable for use in a dry environment, it is easy to rust with water.
② 304 stainless steel, suitable for the outdoor or humid environment, resistant to corrosion
③ 316 stainless steel, added molybdenum, more corrosion resistance and pitting resistance
especially suitable for seawater and chemical media
