Is S500MC, A514 GR.E auto steel alloy plate hot or cold rolled?
34CrMo4 Alloy steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and S500MC, A514 GR.E auto steel alloy plate steel square block. steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. 34CrMo4 alloy steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar S500MC, A514 GR.E auto steel alloy plate can be supplied, providing a quality precision finished bar to tight tolerances.
Q370R steel and 15CrMoR plates have low sulfur and phosphorus content, and have good comprehensive mechanical properties, welding performance and low temperature impact toughness. Q370R low alloy steel is suitable for manufacturing medium temperature and low pressure pressure vessels and their accessories. S500MC, A514 GR.E auto steel alloy plate, 15CrMoR material has low sulfur and phosphorus content, and has good welding performance and impact toughness.
The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The S500MC, A514 GR.E auto steel alloy plate, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In S500MC, A514 GR.E auto steel alloy plate, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
