- Mild steel strip equipment in normal after annealing, three times of cementite and nitride precipitation from the alpha solid solution, then with ferrite as the base substrate can be heated to above Fe - C phase diagram of the PQ, single-phase ferritic organization after heat preservation, and then quenching, due to induce martensitic phase transformation in the ferrite is not, therefore, or ferrite substrates at room temperature. Followed by natural aging for a long time at room temperature or heated to 100-100 ¡æ artificial aging, the carbon to the original? And nitrogen atoms will be precipitated from ferrite partial poly mesh in space or dislocation.At the same time, the e - and e - nitride carbide precipitation in a coherent form? The increased strength and hardness of the material and plastic, toughness drops, appear to yield platform (also called age hardening). For low carbon steel stamping age hardening steel can make sex can deteriorate, slip line or surface wrinkles, and orange peel. So low carbon steel plate should be rapid cooling after annealing, below the line PQ suppression three cementite and nitride precipitation.
Carbon steel and low carbon steel maraging steel band equipment, it is through the supersaturated solid solution strengthening and age hardening process, manganese, molybdenum, niobium, titanium, A1 elements carbonitride precipitated in the form of the aging and implementation to strengthen. Under the condition of quenching hardness of about 30, they can be processed, then at about 450 ¡æ ageing 3-4 h, make 1-3 times the tensile strength, to meet the requirements of the using performance.
