Question 1
1. Why is stainless steel magnetic?
304 stainless steel belongs to Austenite stainless steel. Some or a small amount of Austenite is transformed into martensite during cold working. 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 detection potion detection, if not discoloration for authentic 304 stainless steel.
(2) Supporting spectral ysis of chAcal constituents.
(3) Support smoke test and simulate actual use environment.
Question 3
3. What are the most commonly used stainless steel?
(1) 201 stainless steel, suitable for use in dry environment, easy to rust with water.
(2) 304 stainless steel, outdoor or humid environment, corrosion resistance and acid resistance.
(3)316 stainless steel, added molybdenum, more corrosion and corrosion resistance, especially suitable for seawater and chAcal media.
Since 2003, stainless steel raw materials have risen all over the world, and a kind of "low nickel" cheap and economical stainless steel (containing nickel Ni1.5-4.5%) has emerged in the domestic market, the price is about 15% lower than 304stainless steel, the corrosion and rust resistance is relatively low, and the Bailite products are all Austenite 304or 316stainless steel products.
