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
Spot sales of steel pipes: bid winning steel pipes, American
standard steel pipes, German standard steel pipes, British standard
steel pipes, Japanese standard steel pipes and French steel pipes.
We sincerely welcome friends from all walks of life to visit,
