C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the A709 Gr 50W high strength steel materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
Alloy steel seamless pipe is a kind of high-quality seamless steel pipe with outstanding performance and characteristics. The alloy steel seamless pipe has excellent high-pressure resistance and can withstand greater pressure. Even under pressure, the A709 Gr 50W high strength steel, alloy steel seamless pipe is not easy to break, and it is more safe and reliable to use. It also reduces the loss of pipe material and reduces the maintenance work of pipeline.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. A709 Gr 50W high strength steel Heat treatment process refers to the ability to change the microstructure and properties of A709 Gr 50W high strength steel after heat treatment, including hardenability, hardenability, temper brittleness, etc.
