Description

 

303 stainless steel is an austenitic free-cutting stainless, wear-resistant acid steel. In order to improve the performance of the steel, no more than 0.60% of molybdenum can be added to the steel to resist ablation.
Mechanical properties of 303 stainless steel after annealing and stress relief, the tensile strength is 515MPa, the yield is 205MPa, and the elongation rate is 40%.
303 is a free-cutting stainless steel that contains sulfur and selenium, respectively, and is used in occasions that mainly require free-cutting and high surface finish.

 

Black zinc is used to passivate the black after electroplating zinc. Black zinc plating is a kind of metal anti-oxidation processing, and the black passivation film can be used for decoration, matting and solar heat absorption.

It should be noted that the surface of the black zinc-plated zinc should be black and bright.

First, choose a good passivation solution. The difference between different brands of passivation solution is very large.

Second, the temperature and time control during passivation are different. The product needs different passivation time.

Third, is to pay attention to the drying method.
