O1 Tool Steel

One. Product Description

O1 Tool Steel is a low alloy cold work tool steel with good heat treatment and deformation resistance, and still has good performance at high temperature. Oil quenching must be carried out during heat treatment.

O1 Tool Steel contains a small amount of manganese, tungsten and chromium, making O1 tool steel tough enough for ordinary tools and molds.

O1 Tool Steel has deep hardening properties with a fine grain structure and excellent toughness.

O1 Tool Steel responds well to heat treatment with little dimensional change. The surface has extremely high hardness and high efficiency, so it has excellent wear resistance and easy forging and hardenability, and can be widely used in cutting and cold stamping. O1 Tool Steel offers standard non-carburized round, flat and square bars, as well as the largest selection of flat and drill pipe sizes of all tool steel grades.

Six. Product Detailed Information
O1 Tool Steel is a new type of non-deformable oil steel customized by our company based on years of market summary and current industry demand standards. Oil steel belongs to the improved type of national standard 9CrWMn mold steel, which increases the content of carbon, chromium and tungsten. For 9CrWMn steel, oil quenching can harden workpieces with a diameter of 40-50mm, and the quenching deformation is very small. Therefore, the oil steel introduced by our company is called micro-deformation steel or non-deformation oil steel. Oil Steel adds reasonable tungsten composition according to its own requirements. A more suitable tungsten content will form tungsten coordination carbides and thus have more excess carbonation than Cr12 and 9SiCr steels after quenching and low temperature tempering.

It also has high hardness and wear resistance. In addition, a reasonable tungsten content can also refine the grains, thereby further improving the tempering stability and enabling the oil steel to obtain better toughness. Although quenched retains slightly more retained austenite than other alloy steels and has a similar carbide network, these problems can be eliminated by forging normalizing.
