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.
Low alloyed steel plate Material: Q345B (which is equivalent to S335JR, JIS G3135, DIN EN10025)
Size:
Thickness: 8-200mm
Width: 1800mm
Length: 6000-12000mm
The Q345 is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities. This particular grade of steel is a general purpose manufacturing steel in construction equipment field.
Q345B Yield Strength:
Yield strength of Q345B is 345 Mega Pascal. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.
Q345B 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 Pascal.
Q345B Hardness:
Brinell hardness scale 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.
