不锈钢材质部件表面粗糙度≤20 微米且无明显凹凸和划痕，碳 钢喷涂表面

The surface roughness of stainless steel parts is ≤20 microns without obvious bumps and scratches, and the surface roughness of carbon steel spraying is 40-75 microns, without rust and no obvious bumps and scratches (obvious bumps: slope ≥ 3 degrees; obvious scratches Mark: length ≥50mm). The surface of the equipment is rounded, and the surface is sandblasted, wire drawn, polished, etc.

The surface roughness of stainless steel components is 20 microns and there are no obvious bumps and scratches, the roughness of the carbon steel spray surface is 40-75 microns, no rust and no obvious bumps and scratches (obvious bumps: slope is 3 degrees; obvious scratches: length is 50mm). Equipment surface rounding treatment, surface blasting, wire, polishing and other treatment.

The surface roughness of stainless steel parts is less than or equal to 20 μ m, and there is no obvious concave convex and scratch. The surface roughness of carbon steel spraying surface is 40-75 μ m, without rust and obvious concave convex and scratch (obvious concave convex: slope ≥ 3 degrees; obvious scratch: length ≥ 50 mm).
