HS S136 Steel Applications

  • Injection dies for corrosive materials such as PVC, acetate, or dies that must work and be stored in humid environment.

  • Injection dies that have large use wear (including thermosetting injection molding) or require a long working time, such as electronic parts, disposable meal knives, utensils, etc.

  • The S136 steel can be used in the production of optical products, such as cameras, sunglasses, chemical instruments and plastic products.

HS S136 Steel Features

  • Excellent corrosion resistance

HS S136 steel with molding die design can resist water, water vapor, weak organic acid, diluted nitrate, carbonate, etc.

Molds using S136 steel or equivalent will not be rusty or contaminated for operation in humid environments, or the use of corrosive plastic materials under normal conditions.

Compared with other die steel products, HS S136 steel can particularly show excellent corrosion resistance when tempered at low temperatures and polished to a mirror state.
