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

Excellent hardening rate, suitable for general cold processing and pumping, cold processing performance is better, generally used for hexagonal screws, nuts and washers products

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

Question 1

1. Why does stainless steel bring magnetic

304 stainless steel is austenitic stainless steel, austenite in the cold process of some or a small amount into martensite
, Martensite is a magnetic, so 304 stainless steel is non-magnetic or micro-magnetic. Specific can be related to whether the magnetic content of 304 stainless steel.

Problem 2

2. How to identify authentic 304 stainless steel products?

① support 304 stainless steel detection syrup detection, if not change color for the authentic 304 stainless steel.


② support chemical composition analysis spectral analysis.

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

Problem 3

3. What is the most commonly used stainless steel?

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