Fundamentals of the Heat Treating of Steel

carbon steel and low-alloy steel, the maximum carbon is about 2.0%; in high-alloy steel, about 2.5%. The dividing line between low-alloy and high-alloy steels is generally regarded as being at about 5% metallic al-loying elements (Ref 1).

What is the Q345B carbon steel mechanical properties and

The tensile strength of Q345B carbon steel is eed as the unit of force divided by the cross-sectional area; in the metric system, this unit is called Pascal. 1 Pascal is 1 Newton per square meter in the Q345B carbon steel (the force required to accelerate a 1 kilogram object to 1 meter per second). Q345B carbon steel has a tensile strength of 470 ~ 630 MPa (in millions) and a carbon steel specifications chart, carbon steel 1.2mm-20mm Thick Hot Rolled MS Carbon Steel Plates Q235B Q345B SS400 A36 Grade Steels Manufactory Directly Supply Steel Sheets US $540.00 - $580.00 / Ton
