Spring steel, as we can clearly know from its name, is one of the main materials used to make springs and special alloy steel for other elastic components. ASTM A588 structural steel plate, Spring steel has good comprehensive properties, it has heat resistance, low temperature resistance, oxidation resistance, corrosion resistance and so on advantages. Compared with alloy spring steel, carbon spring steel has less advantages, but its price is cheaper, and the source of raw materials is convenient. The disadvantage of carbon spring steel is that the elastic limit is low and it is easy to lose elasticity after repeated deformation.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the ASTM A588 structural steel plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. ASTM A588 structural steel plate, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.
