Q235B Carbon Steel Pipes

Introduction

Q235B material is a type of low carbon structural steel. Compared with other materials, Q235B contains lower carbon contents (the carbon contents doesn't excess 0.20%). This low carbon content gives Q235B carbon steel pipes with good plasticity and excellent welded performance. Q235B steel have beet impact toughness than Q235A steel, Its impact energy is over 27 J at a temperature of 20℃, which means that Q235B steel is not easy to break or damage when suffering external impact force. It is suitable for general building structure and bridge construction.

 

Features of Q235B carbon steel pipes

High strength and good toughness: Q235B carbon steel pipes have high yield strength (≥235Mpa) and tensile strength (370Mpa-500Mpa). The elongation is more than 26%.

Excellent welding performance: Due to the carbon content is low, Q235B carbon steel pipe has excellent welding performance, convenient for connection between the steel pipe and pipelines.

Good processing harden performance: During cold finished, Q235B seamless steel pipes are able to improve their strength and hardness, meeting different application needs.
