What is the material of die steel S136 and what are its characteristics?

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

The following is a detailed introduction to the characteristics of S136 die steel from the following 7 aspects:

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

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

(3) High hardness: S136 die steel can reach a high hardness level after proper heat treatment. Hardness is usually in the HRC 48-52 range and can even be increased by further heat treatment. This makes S136 die steel ideal for manufacturing molds that require high hardness and wear resistance.

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

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

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

(7) Plasticity and weldability: S136 die 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 by welding repair.

In summary, S136 die steel is a die steel material with excellent corrosion resistance, high hardness, good machining performance, thermal stability and wear resistance. It is widely used in the field of mold manufacturing, especially for mold applications requiring high hardness, wear resistance and corrosion resistance.
