Stainless steel, round steel

Stainless steel round steel belongs to the long material class, and belongs to the rod material class, the so-called stainless steel round steel refers to the cross section for the uniform round long material, generally about four meters long. It can be divided into light circles and black bars. The so-called light circle, refers to the smooth surface, after the quasi-rolling treatment; and the so-called black rod, refers to the black surface, directly hot rolled.

Stainless steel round steel Stainless steel round bar length 4-9 meters belongs to the long materials.

1. Round round steel steel is solid strip steel with circular section. Its specifications are expressed in millimeters in diameter, such as "50" for round stainless steel of 50 mm in diameter.

Common materials are 301,304,303,316,316L,304L,321,2520,201,202, etc. Specifications are indicated in diameter as "50" for round steel of 50 mm. Round steel is divided into three kinds: hot rolling, forging and cold pulling. Hot rolled round steel specification is 5.5-250 mm.

Type:

Stainless steel round steel can be divided into hot rolling, forging and cold pulling. Hot rolled stainless steel round steel specification is 5.5-250 mm. Among them: 5.5-25 mm small stainless steel round steel is mostly supplied in straight bundles, commonly used as steel bars, bolts and various mechanical parts; stainless steel round steel greater than 25 mm, mainly used to manufacture mechanical parts or seamless steel billet.

Oxidation treatment

Sand blasting (ball) method: mainly spray glass beads to remove the black oxide skin on the surface.

Chemical method: using a pollution-free pickling passivation ointment and normal temperature and nontoxic cleaning liquid with inorganic additives for immersion. So as to achieve the whitening treatment purpose of stainless steel true colors. After processing, it basically looks colorless. This approach is more suitable for large, complex products.

Execution Standards

National standard of stainless steel: GB/T1220-2007;

US Standard: ASTM A484/A484M,ASTM A213/213A,ASTM A269/269M;

Surface treatment: industrial surface, drawing surface, bright surface, re-polishing;

Cost calculation: Round Steel Price * [1- (10-discount rate) / 10] + rolling work cost + polishing fee + fixed gauge cost + package + transportation.
