Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. en 10028-2 P265GH, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. en 10028-2 p265gh, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

Compared with en 10028-2 p265gh, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the en 10028-2 p265gh steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The high strength en 10028-2 p265gh low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of en 10028-2 p265gh ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
