Introduction Of The Composition, Advantages And Applications Of Mold Steel S136/S136H

- Jul 25, 2019-

Corrosion resistant high mirror mold steel

mold 10-07


Factory state:

S136H: Pre-hardened to 290-330HB

S136: Annealed to about 200HB, up to 52HRC after heat treatment


Ingredients (%): (for reference only)

C carbon 0.38

Si silicon 0.8

Mn manganese 0.5

Cr chromium 13.6

V vanadium 0.3


Comparison criteria:




Excellent corrosion resistance

Excellent polishing performance

Excellent polishing and machinability

High dimensional stability after heat treatment


Lower maintenance costs:

The mold retains its gloss after long-term use and does not require special maintenance costs for production or storage in wet conditions.


Lower production costs:

Excellent corrosion resistance makes the surface of the mold and the internal water transport channel less prone to rust, so there is a stable cooling cycle to improve production efficiency. Coupled with high wear resistance, the loss is reduced during the production process, resulting in higher tool life and lower production costs.


Main application:

    It can be plasticized with corrosive PVC acetate and other plastic materials, or the mold must be stored in a humid environment.


Suitable for plastic materials with high abrasion resistance of beer and plastics or molds for mass production, such as electronic parts, discarded tableware, utensils, etc.

Production of optical products such as cameras, sun glasses, chemical instruments, syringes, analyzers and plastic products
