Chemical polishing is mainly used in some small batches of complex parts and stainless steel plates that do not have high requirements for brightness, the main advantage of chemical polishing is that it can effectively polish complex parts, and high efficiency, the parts after chemical polishing treatment have good corrosion resistance, and the use of chemical polishing for processing equipment investment is relatively small.
Improper use or maintenance of 304 stainless steel coil will cause rust or yellow spots on the surface of the product, so the following precautions should be understood when using stainless steel coil:
The influence of temperature change: the effect of temperature change of metallurgical spare parts on the thickness of stainless steel strip of rolling equipment is essentially the influence of temperature difference on thickness fluctuation, and the temperature fluctuation is mainly caused by the influence of metal deformation resistance and conflict factor.
For the procurement of stainless steel products, the purchase of 316L stainless steel strip is a frequent problem. So, when purchasing 316L stainless steel strip, what problems should be paid attention to? 1,316L stainless steel strip surface, thickness.
304 and 201 stainless steel is used in stainless steel tanks and the surface is usually matte. So we identify it with the touch of the naked eye and the hand. 304 stainless steel has a good luster and is smooth to the touch of the hand; The color of 201 stainless steel is dark and dull, and the feel is rough but not smooth. Also, wet your hands with water and touch the two stainless steel plates separately. The water-stained fingerprint on the 304 stainless steel plate is easy to erase after touching, while the water-stained fingerprint on the 201 stainless steel plate is not easy to erase.
There are many kinds of stainless steel coil product surfaces, of which 2B and BA are the two most important surfaces. What do 2B and BA mean respectively.
