Heat treatment of hardox 500 welding
Our quality control department will do inspection for details of the steel materials HARDOX 500 welding before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll HARDOX 500 welding, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.
HARDOX 500 welding, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of HARDOX 500 welding, Chinese grade 45 steel depends on its various properties. HARDOX 500 welding, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.
The hot rolling method is to heat the HARDOX 500 welding steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of HARDOX 500 welding rolling process is usually called semi-finished product production, also called blank production.
The high strength HARDOX 500 welding 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 HARDOX 500 welding ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
The HARDOX 500 welding company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest HARDOX 500 welding teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.
