S690QL hot rolled steel weight for pressure vessels

35CrMoA steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, long-term working temperature can reach 500℃; plasticity during cold deformation Medium, poor weldability. Alloy steel S690QL hot rolled steel weight is used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating S690QL hot rolled steel weight production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

S690QL hot rolled steel weight annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S690QL hot rolled steel weight annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S690QL hot rolled steel weight annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. S690QL hot rolled steel weight, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

Our company will accept the product quality objection registration record, pass it to the S690QL hot rolled steel weight production unit and relevant departments, and timely coordinate the supervision of product S690QL hot rolled steel weight quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
