The common materials of color stainless steel plate are 304, 201 and 201 calendering materials.Among them, 304 has higher corrosion resistance than 201, and the normal material is smoother and brighter than the calendering material.Because the price difference is big, many color stainless steel plate manufacturers shoddy, with calendering materials posing as materials, posing as 304 with 201.As a result, the colored stainless steel plates began to fade, rust and even break after a few months.
Therefore, how to avoid the purchase of defective color stainless steel plate by identifying the material?
The first thing to do is to verify that the material is the material you specify.201 and 304 can be used to detect potion resolution, while is material and rolling material mainly by looking at the quality of the panel to distinguish, the material is uniform plate surface smooth smooth, colour and lustre, high brightness, the whole plate, thickness, and rolling material board face slants dark, uneven color, often with black or stripes, the back roller embossing, sand holes, peeling defects such as water mark, the thickness of the plate is poor can reach 2 to 3 C (1 C = 0.01 mm).
But as a lot of manufacturer of chromatic stainless steel plate produce craft and technical rise, the gap of material and calender is being narrowed slowly, some copy is material board, can distinguish with false even true, need has the professional personnel with rich experience ability to distinguish.
