Products Description
The major benefit of Q345 steel is its mild temper, easy to form and weld. Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572.
Yield Strength
A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Yield strength of Q345B is 345 Mega Pascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.
Tensile strength
The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example breaking. Steel tensile strength is expressed in units of force divided by cross sectional area; in the Metric system, this unit is known as the Pascal. One Pascal is a Newton per square meter. The tensile strength of Q345 steel is rated at 470 to 660 Mega Pascals.
Hardness
Brinell scale hardness characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science.
S355J2G3 steel is a carbon manganese ,high yield non alloy steel. It is called S355 because of the average minimum yield for this material is 355 Mpa.As a structural steel,it has excellent strength and weldability.It can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties. S355J2G3 is generally supplied in a normalized condition.
