S136 Plastic mould steel
Product Overview
S136 Plastic mould steel is a premium martensitic stainless tool steel, internationally recognized for its exceptional mirror-polishing capabilities and superior corrosion resistance. Through advanced refining processes (often ESR), S136 achieves a high level of micro-purity and an extremely fine structure. It is specifically designed for moulds that must withstand corrosive plastic materials (like PVC) or operate in humid environments while maintaining an impeccable, high-gloss surface finish over long production cycles.

4.S136 Plastic mould steel Key Features:
Superb Mirror Polishability: Capable of achieving optical-grade finishes (#8000-#12000 grit) for high-transparency parts.
Excellent Corrosion Resistance: Highly resistant to corrosive plastics and cooling water, reducing maintenance and mould downtime.
Superior Machinability: Provides stable and predictable cutting performance in its annealed state.
High Wear Resistance: Reaches 50-54 HRC after heat treatment, ensuring a long mould service life even under abrasive conditions.
Remarkable Dimensional Stability: Minimal distortion during the hardening and tempering process, ideal for high-precision components.
Low Maintenance Costs: Eliminates the need for specialized anti-rust coatings during storage or production.
5.S136 Plastic mould steel Typical Application:
Optical Components: Camera lenses, eyeglasses, light guides, and high-transparency screens.
Medical Devices: Syringes, blood analysis containers, and clean-room grade medical tools.
Premium Packaging: High-gloss cosmetic cases, perfume bottles, and luxury electronics housings.
Corrosive Plastics: Moulds for processing PVC, acetates, or plastics containing flame retardants.
