Q690 steel and Q690M material is a Chinese GB standard high strength low alloy structural steel, and devides into 3 quality grades: Q690C, Q690D and Q690E, “Q” means Yield Strength, “690” refers to 690 Mpa, Tensile Strength is 770-940 Mpa, “M” is short for “TMCP” (Thermal Mechanical Control Processing), for data sheet and specification, please refer to the following tables.
Steel plates made from Q690 material has high yield strength and tensile strength and is widely used in coal mine machinery and engineering machinery, such as hydraulic support, port cranes, flatbed trucks and so on.
The chemical compositon of <CLASS C D E> are displayed in the following table.
