304-A2 0.1 1 2 0.05 0.03 15-20 8-19 4

Work hardening rate is moderate, suitable for general cold processing and stretching, cold processing performance is better, generally used for hexagonal screws, nuts and gasket products

316-A4 0.08 1 2 0.045 0.03 16-18.5 2-3 10-15 1

Plus molybdenum, corrosion resistance than 304 strong, especially for seawater and chemical media, more corrosion resistance and pitting resistance.

Note:

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%, then the minimum nickel content of 12%
4) For the maximum 0.03% carbon content of austenitic stainless steel, nitrogen content of up to 0.22
5) For larger diameter products, in order to achieve the specified mechanical properties in the manufacturer's instructions, may have a higher carbon content, but martensitic steel should not exceed 0.12%

Question 1

1. Why stainless steel with magnetic?

304 stainless steel is austenitic stainless steel, austenite in the cold part of the process or a small amount into martensite
, Martensite is magnetic, so the 304 stainless steel is non-magnetic or micro-magnetic. Baidu query can be specific why 304 stainless steel with magnetic.

Problem 2

2. How to identify genuine 304 stainless steel products?

① support for testing 304 stainless steel syrup detection, if not discolored to authentic 304 stainless steel.


② support the chemical composition analysis of spectral analysis.

③ support smoke test, simulate the actual use of the environment.

Problem 3

3. The most commonly used stainless steel that several?

①.201 stainless steel, suitable for use in dry environments, water is easy to water rust.
②304 stainless steel, outdoor or humid environment, strong acid corrosion resistance.
③ 316 stainless steel, plus molybdenum, more corrosion resistance and pitting resistance, especially for seawater and chemical media.
