How to select grade p235gh steel material alloy steel

Pageviews:

Q345 is a grade of carbon structural steel. Q is the meaning of yield strength, which grade P235GH steel material is taken from the initial of Chinese Pinyin of "Qu"; 345 is the value of yield point, in MPa. Q345 refers to carbon structural steel with yield point (σ s) of 345mpa. The following letters indicate the quality level, including A, B, C, D and E. Q345 steel has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. Q345 steel is usually in hot rolling or normalizing state.

The advantages of grade p235gh steel material, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

TMCP process is an indispensable technology for our production of low alloy high strength wide and grade p235gh steel material thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy grade p235gh steel material and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.
