Q345 Steel
Material Notes:This material has a yield strength of 345 MPa and a tensile strength of 470 MPa to 660 MPa which guarantees that it is quite durable. The composition includes carbon which is ≤0.20%, silicon ≤0.55% and manganese 1.00% – 1.60% which allows the material to be strong but also ductile and weldable at the same time.
Applications: Motor vehicles and machinery: Frames, chassis and their mechanical components. Construction: such structures as beams, columns and other parts of buildings and bridges. Marine and shipbuilding: marine vessels hulls and supporting structures. Tank and vessel manufacturing: low pressure gas and liquid storage tanks.
