Question 1

1. Why does stainless steel have magnetism?

304 stainless steel belongs to the Aolite stainless steel, The Oshistis in the cold processing process has some or a small amount of conversion into the horse body
The martensite is magnetic, so 304 stainless steel is non-magnetic or micro-magnetic. Baidu can inquire why 304 stainless steel contains magnetism.

Question 2

2. How to identify authentic 304 stainless steel products?

① support 304 stainless steel special testing solution detection, if it does not change color, it is authentic 304 stainless steel.
② support chemical component analysis and spectral analysis.
(3) Support smoke test and simulate actual use environment.

Question 3

3. What kinds of stainless steel are most commonly used?

①.201 stainless steel, suitable for use in dry environment, easily rusts when exposed to water.
② 304 stainless steel, outdoor or humid environment, strong corrosion and acid resistance.
3316 stainless steel, Mo, more corrosion resistance and pore corrosion resistance, especially suitable for seawater and chemical media.

Since 2003, the raw materials of stainless steel in the world have increased. A kind of “low nickel” low-cost economic stainless steel (including nickel ni1.5-4.5%) austenitic stainless steel has appeared in the domestic market. Its price is about 15% – 40% lower than that of 304 stainless steel. Its anti-corrosion and anti rust ability is relatively low. Bairuite products are all Austenitic 304 or 316 stainless steel products.
