Stainless steel cylinder tube has excellent performance characteristics

- Sep 03, 2019-

The inner diameter of the stainless steel cylinder tube indicates the output force of the cylinder. The piston should slide smoothly in the cylinder, and the inner surface roughness of the cylinder should reach ra0.8um. The inner surface of the steel pipe column should be plated with hard chrome to reduce friction and wear and prevent corrosion. The cylinder material is made of high-strength aluminum alloy and brass, except for high-carbon steel pipes. This small cylinder is made of stainless steel. In corrosive environments, cylinders using magnetic switches or cylinders should be made of stainless steel, aluminum or brass.


By expanding in the engine cylinders, the cylinders are converted to mechanical energy. The piston in the compressor cylinder compresses the gas to increase the pressure. The outer casing of a turbine or rotary piston engine is commonly referred to as a cylinder. Application of stainless steel cylindrical tubes: printing (tension control), semiconductor (spot welder, chip grinding), automatic control, robots, etc.


The Rockwell hardness test of cylindrical tubes is actually the same as the Brinell hardness test, the indentation test method, but the difference is that Rockwell mainly measures the depth of the indentation, and the Rockwell hardness test method is widely used because The hardness is suitable for testing soft metal materials, effectively making up for the insufficient Brinell hardness test, and the relatively simple method of the method. However, due to the small indentation, the hardness value is not as accurate as the Brinell hardness value.
