O1 STEEL CHARACTERISTICS
O1 mold steel is a widely used oil quenched hardening tool steel with good wear resistance and processing performance. Due to its stable heat treatment performance, its dimensional deformation is very small. In addition, O1 mold steel has a good distribution of carbides and small particles, which helps to improve its wear resistance. In addition, the steel has good hardenability and small quenching deformation.
In practical applications, O1 steel exhibits excellent characteristics. Firstly, due to its characteristics of spheroidizing, annealing, and softening of the microstructure, it is easy to carry out cutting processing. Secondly, quenched O1 steel has high hardness and good dimensional stability after tempering. In addition, for hardened steel, softening annealing can be used to improve its cutting performance; The precision mold after rough machining needs to undergo stress relief annealing treatment.
In terms of hardness and wear resistance, ASTM O1 tool steel is considered to have deep hardening characteristics and fine grain structure, exhibiting excellent wear resistance and toughness. In practical applications, O1 steel is often used in hardware molds such as punching dies, stamping dies, bending dies, drawing dies, piercing punches, and finishing dies. However, it is worth noting that although O1 steel performs well in wear resistance and dimensional stability, its toughness and corrosion resistance are relatively weak.
O1 steel is widely used due to its excellent processing performance, wear resistance, and stable heat treatment performance. However, attention should also be paid to the limitations of its strength and corrosion resistance when using it.
