Pre-Hardened Mold Steel Material Increases Through-Hardened Ability

Global supplier of high-quality mold materials Finkl Steel highlights its  patented pre-hardened mold steel grade MD Xtra. The through-hardened material is said to achieve high impact strength, enhanced thermal conductivity and is a solution for deep cavity applications.

According to Finkl Steel, MD Xtra has proven through-hardenability on molds up to 45" thick, with hardness loss from surface to the core of roughly 3 HRC points. The material has been specifically engineered to support laser hardening, chrome plating, nitriding, texturing and has excellent weldability. One of the added benefits, says the company, is that customers will not need to change the weld material from what is being used on standard MD material. According to the company, MD Xtra is currently used in molds that require high wearability, including glass-filled parts.

MD Xtra is also offered in the “Super-Hard” condition at 38-43 HRC for high-polish requirements and a vacuum arc re-melt version MLQ Xtra for a high-gloss finish (SPI A1 or greater).

Finkl Steel retains two primary melt facilities, three forging facilities and various warehouses, with a strong presence in the U.S. Canadian markets.
