Stainless steel bars are hot rolled or forged from stainless steel ingots.

The production of stainless steel bars emerged with the development of stainless steel. Due to the increasingly wide range of applications of stainless steel bars, such as the foundation of high-rise buildings in cold areas, isolation nets beside highways, household items, etc., the hot-rolled production of stainless steel bars has been greatly developed. 30% of stainless steel products in my country %, foreign countries only account for 8%-10%. With the rapid development of cutting-edge technologies such as petroleum, chemical industry, energy and atomic energy, aerospace, and marine development, higher comprehensive performance requirements have been put forward for stainless steel, which not only requires good corrosion resistance, but also requires high strength, high temperature and high pressure resistance. , radiation resistance, low temperature resistance and other properties, so that the types of stainless steel have been further developed.

Production process and classification

Stainless steel bars are hot rolled or forged from stainless steel ingots.

According to the shape, it can be roughly divided into: stainless steel round bar, stainless steel square bar, stainless steel hexagonal bar.

According to the surface treatment, it can be divided into: stainless steel black rod, stainless steel acid white rod, stainless steel bright rod, stainless steel grinding rod.

Use

Mainly used for aircraft engine blades, casings, fasteners, combustion chambers, discs, shafts, combustion chamber walls, liquid oxygen kerosene engines, bomb bodies, gas cylinders, propulsion devices, etc. Widely used in aerospace, aviation, atomic energy, nuclear energy, petroleum, chemical industry, and food, environmental protection, marine development, boiler heat exchangers and other fields.
