The inner diameter of the stainless steel cylinder tube indicates the output force of the cylinder(made by 304 or 316stainless steel cylinder tubes). 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/tube column should be plated with hard chrome to reduce friction and wear and prevent corrosion. The cylinder material is aluminum alloy and brass, except high carbon steel pipe. This small cylinder is made of stainless steel. Cylinders using auto switches or cylinders should be stainless steel, aluminum or brass.
By expanding in the engine cylinders, the cylinders are converted into mechanical energy. Pistons in compressor cylinders compress gas to increase pressure. The casing of a turbine or rotary piston engine is often referred to as a cylinder. Applications of stainless steel cylindrical tubes: printing (tension control), semiconductor (spot welding machine, chip grinding), automatic control, robotics, etc.
The Rockwell hardness test of the cylindrical tube 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 Rockwell hardness test method is widely used. Brinell hardness is suitable for testing soft metal materials, making up for the deficiencies of Brinell hardness testing, as well as a relatively simple method. However, due to the small indentation, the hardness value is not as accurate as the Brinell hardness value.
