Product Description
YMT 2083ESR
YMT2083ESR is an exceptional medium carbon, high chromium alloy, stainless mold steel (Cr>12.5%), expertly crafted for the production of injection molds. These molds effectively release corrosive gases when heated and are designed for molds requiring an efficient cooling system using water to maintain superior cooling effects.
*Remarkable through-hardening capability
*Exceptional hardness
*Outstanding polishing results
*Superior resistance to corrosion.
Chemical Composition (%)

| % in weight | ~0.38 | ~1.00 | ~0.60 | ~13.00 | ~0.25 | ~0.30 | |
Key Applications
Ideal for injection molding with corrosive resins like PVC, and the extrusion forming of thermosetting resins. It is perfect for creating phenolic (electric wood) electrical insulation devices, semiconductor seals, and mass production of disposable tableware including fast food boxes, spoons, knives, and forks. These products demand high polishing effects and exceptional corrosion resistance. YMT2083ESR SUP is an excellent choice, delivering features such as preventing cooling water rust, maintaining rapid cooling, and reducing injection cycles. Suitable for high-end products like:
Cameras, glasses, magnifying glass lenses, disposable needles, cups, premium cosmetic containers, and more.
