Q345 is a kind of steel material. It is carbon alloy steel (C<0.2%), good="" overall="" performance="">
Widely used in Bridges, vehicles, ships, buildings, pressure vessels, etc.
Q represents the yield of this kind of material. 345 in the back refers to the yield value of this kind of material, which is about 345MPa. The yield value decreases with the increase of the thickness of the material.
345 Steel Properties and Introduction
Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa (datasheet tested with 16mm diameter steel bars or steel plates). According to GB/T 1591 – 2008, Q345 material has 5 quality grades: Q345A, Q345B, Q345C, Q345D and Q345E. “Q” is the first letter of Chinese Pinyin: “qu fu dian”, which means Yield Point, “345” is short for 345 MPa. For datasheet and specification, please see the tables below.
