Postalloy® DuraChrome™
Description
Postalloy®  DuraChrome™ 2837-MCO is specifically designed to produce a high concentration of fine chromium carbides in an austenitic matrix. The fine dispersion of chromium carbides greatly improves the abrasive wear resistance and impact toughness compared to ordinary chromium carbide products. DuraChrome™ 2837-MCO can be applied to carbon steels, low alloy steels, manganese steels and cast iron rolls.

Very consistent crack pattern makes DuraChrome™ 2837-MCO an excellent choice for multi-layer hardface applications.This helps reduce the probability of spalling and chipping.

The weld deposit is not machinable and will withstand hot wear applications up to 1000°F (538°C).
