Q370q steel is a kind of bridge steel plate. It is delivered in hot rolled, normalized condition. There are three quality levels Q370qC, Q370qD, and Q370qE. Bridge steel Q370qC, Q370qD, A283 grade D ms steel sheet and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃. Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated. When mechanical properties are required, large thickness must be normalized. The thickness of Q370q steel plate we supply is above 8mm.
Heat treatment advantages of A283 grade D ms steel sheet, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.
BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our A283 grade D ms steel sheet office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase A283 grade D ms steel sheet 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge A283 grade D ms steel sheet stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel.
