Product Description

GB/T8162 25Mn Seamless Carbon Steel Tube For Structure


GB/T8162 Seamless Carbon Steel Pipe As seamless steel tubes and Seamless Carbon Steel Tube, its main purpose is For Structure Purposes. As Hydraulic Cylinder Steel TubeUnder normal circumstances, its main material is 10# 20# 25# 35# 45# 20Mn 25Mn.1 the hot rolled steel pipe should be delivered in hot rolling or heat treatment state, and require the heat treatment state to be indicated in the contract when the heat treatment state is delivered. 2 the cold drawn steel pipe should be delivered in heat treatment. In accordance with the buyer's request, the two parties shall negotiate and indicate in the contract that they can also be delivered in a cold drawn state.

We are manufacturer of Seamless Steel Tubes in China, if you want to buy Seamless Carbon Steel Tube, Oil Cylinder Steel Tube, Precision Seamless Steel Tube, Hydraulic Cylinder Steel Tube, please contact us.
