Product Description

Product Description

1. Technology of Hot Rolled, Cold Rolled or Cold drawn.
2. Hollow cross-section with lighter weight and higher pressure.
3. High hardness, strength, wear resistance and anti-corrosion.
4. The SMLS can becut, threaded or grooved. And the coating method includes black / red lacquer, varnish painting, hot dip galvanization, etc.
8620 steel pipe is high quality alloy structural steel, this kind of steel usually in accordance with the requirements of use after heat treatment have good strength, hardness, and toughness, or surface wear resistance and heart has good toughness and impact resistance. Gear steel is one of the key materials which require higher requirements in special alloy steel used in automobile, railway, ship and engineering machinery, and it is the manufacturing material of the core components to ensure safety. Gear steel is developing towards the direction of high performance, long life, smooth gear operation, low noise, safety, low cost, easy processing, variety and so on. Gear steel is used to make gear parts for wind power, machinery and other industries.
