St52 Seamless Steel Pipe For Structural Purpose

Introduction

Grade ST52 is a low alloy and high strength steel that complies with DIN1629 standard, which is equivalent to Q345B of GB standard. It plays a crucial role in various engineering projects and mechanical manufacturing due to its excellent tensile strength and yield strength. From the stable structure of civil buildings to the safety support of underground engineering; From bridge structures to complex ocean structures, St52 steel is a ideal material.

St52 steel contains multiple chemical elements, including carbon, phosphorus, and sulfur, etc. These chemical elements give St52 steel with high strength and excellent mechanical properties, making it suitable for various structural purpose.
