ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. A572 Gr 55 high strength steel, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A572 Gr 55 high strength steel is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15~40mm during oil quenching. When the hardness is HB174~229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and A572 Gr 55 high strength steel steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and A572 Gr 55 high strength steel medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
It is a modern high-tech professional enterprise integrating scientific research, A572 Gr 55 high strength steel production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A572 Gr 55 high strength steel process technology development, technology transfer and related technical consulting and technical services.
