Description

China Shandong Baote metal products Co., Ltd. specializes in producing steel pipe diameter: 6mm****0mm!

Perennial sales: all kinds of seamless steel pipe, precision steel pipe, bright steel pipe, medium and thick wall steel pipe, cold drawn steel pipe, alloy steel pipe, medium and high pressure steel pipe, special equipment pipe, marine steel pipe, gas cylinder pipe, geological drilling pipe, oil casing, hydraulic support pipe, fluid pipe, stainless steel pipe, welded pipe, square pipe, etc.

Round steel is divided into hot rolling, forging and cold drawing. The specification of hot rolled round steel is 5.****0mm. Among them: small round steel of 5.***5mm is mostly supplied in bundles of straight bars, which is often used as reinforcement, bolts and various mechanical parts; Round steel larger than *5mm is mainly used for manufacturing mechanical parts, pipe blank of seamless steel pipe, etc.

Classification by chemical composition

Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (i.e. carbon content).

(1) Low carbon steel

Also known as mild steel, low carbon steel with carbon content from 0.*0% to 0.*0% is easy to accept all kinds of processing, such as forging, welding and cutting. It is often used to manufacture chains, rivets, bolts, shafts, etc.

(2) Medium carbon steel

Carbon steel with carbon content of 0.*5% ~ 0.*0%. There are killed steel, semi killed steel, boiling steel and other products. In addition to carbon, it can also contain a small amount of manganese (0.*0% ~ 1.*0%). According to the product quality, it is divided into ordinary carbon structural steel and high-quality carbon structural steel. Good hot working and cutting performance, poor welding performance.

The strength and hardness are higher than those of low carbon steel, while the plasticity and toughness are lower than those of low carbon steel. Hot rolled and cold drawn materials can be directly used without heat treatment, and can also be used after heat treatment. The medium carbon steel after quenching and tempering has good comprehensive mechanical properties. The maximum hardness that can be achieved is about HRC*5 (hb**8), σ B is **0 ~ ***0mpa. Therefore, medium carbon steel is the most widely used in various applications with medium strength level. In addition to being used as building materials, it is also widely used to manufacture various mechanical parts.

(3) High carbon steel

It is often called tool steel. The carbon content ranges from 0.*0% to 1.*0%. It can be hardened and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.*5%; Cutting tools such as drills, taps, reamers, etc. are made of steel with a carbon content of 0.*0% to 1.*0%.

Various types of steel pipes and non standard steel pipes can be created by suppliers
