Product Description
YMT2083ESR is a medium carbon, high chromium alloy, stainless mold steel (Cr>12.5%), suitable for the production of injection molds which release corrosive gas while heated in production, or molds that require cooling water to maintain efficient cooling effect.

*Good through-hardening property  
*High hard 
*Excellent polishing effect 
*High corrosive resistance.
Main Application
Apply on injection molding with corrosive resin, such as PVC; extrusion forming thermosetting resin, manufacture of phenolic (electric wood) electrical insulation devices, and semiconductor seals, mass production of disposable tableware, fast food boxes, spoons, knives and forks (from which function as preventing cooling water rust, maintaining rapid cooling, shortening the injection cycle) need higher polishing effect and higher corrosion resistance. It is recommended to choose YMT2083ESR SUP, with the following products:

Cameras, Glasses, Magnifying glass lenses, disposable needles, cups, premium cosmetic containers, etc.
