EN 10028 P460M plates marking, No.45 seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of No.45 seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.
EN 10028 P460M plates marking, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. EN 10028 P460M plates marking, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. EN 10028 P460M plates marking, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.
Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter EN 10028 P460M plates marking steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
