41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.
Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of A572 Gr 60 high strength steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and A572 Gr 60 high strength steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
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 A572 Gr 60 high strength steel 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 A572 Gr 60 high strength steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
The common delivery status of A572 Gr 60 high strength steel, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
