The hot rolling process of Q235NH weathering steel

We do sand blasting and shop primer for various Q235NH weathering steel steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer Q235NH weathering steel thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

Cold rolled steel sheet has high strength, high hardness, high surface finish and is generally thin plate, which can be used for stamping. The production process of Q235NH weathering steel, hot-rolled and cold-rolled steel plates is different. Hot rolled steel plate is rolled at high temperature, while cold rolled steel plate is rolled at normal temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.

The high strength Q235NH weathering steel 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 Q235NH weathering steel ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.

Firmly establish the "people-oriented, safe development" concept, strictly follow the safety production policy of "safety first, prevention first, comprehensive management", strengthen and improve the management and supervision of safety production in an all-round way, and strive to improve the controllability of safety management And effectiveness, cultivate safety culture, improve long-term safety production mechanism, and build a harmonious BEBON.
