Ways to improve the qualified rate of bp300 steel heat treatment

Over the years, the company has established a standard of BP300 steel heat treatment steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to BP300 steel heat treatment quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

BP300 steel heat treatment, No.45 seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of No.45 seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. BP300 steel heat treatment, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
