After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of sa573 grade 58, 65, 70 carbon steel plate smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while sa573 grade 58, 65, 70 carbon steel plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of sa573 grade 58, 65, 70 carbon steel plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
A36 plates technical parameters, A36 ms steel sheets datasheet: A36 steel consists of carbon 0.25% max., phosphorus 0.040% max., sulphuric 0.050% max., silicon 0.40% max. and copper 0.20% max.
