? Wuxi Duorunde Steel Tube Co., Ltd (My Answer); Precision steel tube and stainless steel tube are both high-quality steel tube materials, which are processed through many procedures during the manufacturing process, and have the characteristics of high precision, high strength, and high abrasion resistance. However, there are still some differences between them.
First of all, precision steel tubes and stainless steel tubes are made of different materials. Precision steel tubes are usually made of low carbon steel, medium carbon steel or alloy steel as raw materials, and are processed through multiple cold drawing and cold rolling processes. Stainless steel tubes are made of stainless steel as raw material, processed through multiple cold-drawing and cold-rolling process.
Secondly, the performance of precision steel tubes and stainless steel tubes is different. Precision steel tube has good plasticity and toughness, suitable for the manufacture of some of the higher strength requirements of the parts, such as automotive drive shafts, machine tool spindles and so on. Stainless steel tube has good corrosion resistance and high temperature performance, suitable for manufacturing some parts working in corrosive environments, such as chemical equipment, medical equipment.

In addition, the surface treatment of precision steel tubes and stainless steel tubes are different. Precision steel tubes usually use polishing, grinding, pickling and other surface treatment methods, so that the surface of the steel tube is smoother and more accurate. Stainless steel tube is usually pickled, passivated, sandblasted and other surface treatment methods, so that the surface of the steel tube is smoother and more corrosion resistance.
20# Precision Steel Tube, 45# Precision Seamless Tube, Cold Drawn Precision Steel Tube, Cold Rolled Precision Bright Tube, etc. are all different types of precision steel tubes. These different types of precision steel tubes in the manufacturing process, materials, performance and application of certain differences.
20# Precision Steel Tubes are made of 20 gauge steel as raw material and processed through multi-stage cold drawing and cold rolling process. It has high strength and hardness, and is suitable for manufacturing some parts that require high wear resistance, such as piston rods and bushings.
45# Precision Seamless Tubes are made of No.45 steel as raw material, which is processed by piercing, rolling and sizing. It has high strength and hardness, and is suitable for manufacturing some parts that require high abrasion resistance, such as transmission shafts and support shafts.
Cold-drawn precision steel tubes are made of low carbon steel or alloy steel as raw material, processed through multiple cold-drawn processes. It has high strength and hardness, and is suitable for the manufacture of some parts that require high strength, such as automobile transmission shafts, machine tool spindles, etc.
Cold Rolled Precision Bright Tubes are made of low carbon steel or medium carbon steel as raw material, and processed by multi-pass cold rolling process. It has high precision and surface smoothness, and is suitable for manufacturing some parts that require high precision, such as automobile cylinder block and hydraulic cylinder barrel.
In short, precision steel tubes and stainless steel tubes are high-quality steel tube materials, they are in the manufacturing process, materials, performance and application of certain differences. When choosing and using them, you need to judge and choose according to the specific application scenarios and requirements. At the same time, its processing and treatment also need to be strictly controlled to ensure that the manufactured mechanical components have high quality and performance.
