SA516GR70N steel is a standardized medium and low temperature pressure vessel. The overall performance is improved and the ASTM A572 ms steel coil product price is higher. The steel plate has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-laminar cracking performance, low carbon equivalent, and strong resistance to sulfur and hydrogen. The products available for steel plates with a thickness of less than 200mm.
The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with ASTM A572 ms steel coil good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.
Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled ASTM A572 ms steel coil products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the ASTM A572 ms steel coil rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
The microstructure of the quenched and tempered alloy steel, ASTM A572 ms steel coil after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
