Which Types of Stainless Steel Doors are Commonly Used
Stainless steel doors are made of various kinds of materials, and normally are 304/304L/316/316L/321/310S 410/420/420J1/420J2/430/ 201/202
How to identify the quality of different types of stainless steel doors materials is not determined by an individual, but has to be analyzed through chemical methods.
Such as the identification of 400 and 300 series can be done by magnetic method, 400 series material is generally magnetic but 300 series is not. Also 301 series has good ductility which can be used in finished products. This series material can also be rapidly hardened by machining, So it's weldability, abrasion resistance and fatigue strength is better than 304 series materials.
Model 302 has the same corrosion resistance as 304 serie.. Read More
