Cr12MoV hot rolled steel round bars information
Cr12MoV steel has high hardenability, and those with a cross-section of 300 to 400 mm or less can be completely quenched
It can maintain good hardness and wear resistance at 300 ～ 400℃, its toughness is higher than Cr12 steel, and its volume change is minimal during quenching. It can be used to manufacture various molds and tools with large cross-sections, complex shapes, and withstand large impact loads. For example, punching dies with complex shapes, inserts on complex dies, steel deep drawing dies, wire drawing dies, threaded wire plate, cold extrusion dies, cold cutting scissors, circular saws, standard tools, measuring tools, etc.
Cr12MoV steel is a high-carbon, high-molybdenum lysic steel. Its carbon content is much lower than that of Crl2 steel, and it is added with molybdenum and vanadium elements, which significantly improves the steel's thermal processing properties, impact toughness and carbide distribution . The steel has high wear resistance, hardenability, hardenability, toughness, thermal stability, compressive strength, as well as micro deformation, excellent comprehensive performance and extensive adaptability. The heat softening temperature is 520℃. The cut-off size is below 4mm and can be completely hardened. The wear resistance of this steel is 3~4 times higher than that of a low-strength tool steel, and the quenching volume is small. Hardening depth: oil quenching 200~300mm.
During the crystallization process, a large number of eutectic white carbides are formed (the carbonized substance fraction is about 20%, and the eutectic temperature is about 1150°C). These carbides are very hard and brittle. Although the carbides are broken to a certain degree after billet rolling, the carbides are distributed in bands, slabs, blocks, and piles along the rolling direction, and the degree of segregation increases with the diameter of the steel.
