12mm thick S690QL high strength steel plates

Characteristics of 50CrMo4 steel: 50CrMo4 steel has high strength and toughness, good hardenability and no obvious tempering brittleness. 50CrMo4 steel is suitable for manufacturing large and medium-sized plastic mould with certain strength and toughness. 50CrMo4 steel can be used to manufacture the big gear for locomotive traction, booster drive gear, S690QL high strength steel plates pressure vessel gear, rear axle, connecting rod and spring clamp with great load, as well as the drill pipe joint and fishing tool for oil deep well below 2000m, and 50CrMo4 steel can also be used for the die of bending machine, etc.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials S690QL high strength steel plates used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than S690QL high strength steel plates, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
