Cold Rolled Q345 Carbon Steel Rod 200mm Mild Steel Round Bar Plain Finish
The yield value of Q345 will decrease with the increase of material thickness, and the domestic ones may be less than 345MPa, so the strength must be less than 345MPa in mechanical design, otherwise there will be problems.
With the development of modern industry and the continuous progress of science and technology, various trace elements are more widely used in steel plates. Mn content is no longer the only factor affecting the strength and mechanical properties of steel. Therefore, the low alloy high strength structural steel standard jointly issued and implemented by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Administration of China cancels the limit of the range of Mn content and only specifies the maximum value.
For the detection of Q345 steel, on the one hand, it is whether the element content of the steel meets the requirements of the national standard, and on the other hand, it is most important to check whether the mechanical properties (yield strength, tensile test) of the steel meet the standards through professional institutions.
