35# steel pipe

35# steel pipe is a kind of material in steel. It is a high-quality carbon structural steel.

35 of 35# steel pipe refers to the carbon content in this material, which is about 350. This material is also more common than other high-quality carbon steels.

General use steel pipe:
It is made of high-quality carbon steel such as 10, 20, 30, 35, and 45; low-alloy structural steel such as 16Mn and 5MnV, or hot-rolled or cold-rolled alloy steel such as 40Cr, 30CrMnSi, 45Mn2, and 40MnB.

Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transportation pipelines. 45. Seamless pipes made of medium carbon steel such as 40Cr are used to manufacture mechanical parts, such as the stressed parts of automobiles and tractors.

Generally, seamless steel pipes are used to ensure the strength and flattening test. Hot-rolled steel pipes are delivered in hot-rolled state or heat-treated state; cold-rolled steel pipes are delivered in heat-treated state

Chemical composition of 35# steel pipe:

Grade	C	Si	Mn	P	S	Cr	Ni	Cu
35	0.32~0.40	0.17~0.37	0.50~0.80	≤0.35	≤0.04	≤0.25	≤0.25	≤0.25

Classification of 35# steel pipes: seamless steel pipes are divided into two categories: hot-rolled and cold-rolled (dial) seamless steel pipes.

Hot rolled steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (pulled) seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Stainless thin-walled steel pipe, special-shaped steel pipe.
