Detailed Introduction

Mechanical tubes are mainly used for subsequent machining, cold-drawn steel processing, construction machinery and other machinery processing industry.

Main steel grade

Common steel grade:20#、45#、16Mn(Q345B)、25Mn、30CrMo、35CrMo、42CrMo、ANSI 1026、ANSI 4130、ANSI 4140、ANSI 4340。

Excutive Standard 

GB/T 8162 Seamless pipe for structural purpose;

GB/T 8163 Seamless steel pipe for liquid service;

ASTM A519

Seamless carbon steel & alloy mechanical tubing;

Product features

Mechanical tubing has good size, diameter ovality and bore roundness, especially for the thick-walled pipe which has a thickness of more than 20mm, it can still achieve the better bore roundness.

Application environment for products

The steel grade in 20#&45# are mainly used for general engineering use or the mother tube which is used for cold-drawn low-pressure hydraulic cylinder.

The steel grade in 16Mn, 25Mn&ANSI 1026 are mainly used for processing construction machinery industry, especially the steel grade 25Mn could be used as mother tube of high pressure hydraulic cylinder

The steel grade in 30CrMo, 35CrMo, ANSI 4130, ANSI 4140&ANSI 4340 has high strength and excellent toughness, it can be processed as high strength machined products, an it can be also used for processing high-strength tools which has some corrosion resistance and so on.
