What is S136 Mold Steel and What are its Characteristics?

S136 mold steel is a high-quality stainless steel material, also known as 420SS or 4Cr13. It belongs to martensitic stainless steel, has good corrosion resistance and high hardness, and is widely used in mold manufacturing.

The following seven aspects will introduce the characteristics of S136 mold steel in detail:

(1) Chemical composition: The chemical composition of S136 mold steel mainly includes carbon (C), chromium (Cr), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. Among them, the high chromium content can provide excellent corrosion resistance and oxidation resistance.

(2) Corrosion resistance: S136 mold steel has good corrosion resistance and can be used for a long time in a humid environment without rusting. This makes it suitable for manufacturing molds that need to be related to moisture, acid and alkali.

(3) High hardness: S136 mold steel can reach a high hardness level after proper heat treatment. The hardness is usually between HRC 48-52, and the hardness can even be increased by further heat treatment. This makes S136 mold steel very suitable for manufacturing molds that require high hardness and wear resistance.

(4) Excellent cutting performance: S136 mold steel has good cutting performance and is easy to perform cutting, milling, drilling and other processing operations. This allows manufacturers to more easily process and shape molds with complex shapes.

(5) Good thermal stability: S136 mold steel has good thermal stability and can maintain good hardness and strength in high temperature environments. This makes it suitable for mold applications that need to withstand high temperature shock and pressure.

(6) Excellent wear resistance: S136 mold steel has excellent wear resistance and can resist friction and wear. This makes it very suitable for manufacturing molds that need to be used for a long time and require high wear resistance.

(7) Plasticity and weldability: S136 mold steel has good plasticity and weldability, which is convenient for mold forming and assembly. At the same time, it can also extend the service life of the mold through welding repair.

In summary, S136 mold steel is a mold steel material with excellent corrosion resistance, high hardness, good cutting performance, thermal stability and wear resistance. It is widely used in the field of mold making and is particularly suitable for mold applications that require high hardness, wear resistance and corrosion resistance.
