Postalloy® DuraHard™
2898-MCG (formerly part 2898-SPL)

Abrasion resistant Postalloy® DuraHard™ 2898-MCG is a general purpose self-hardening overlay with a good combination of resistance to abrasion and impact. DuraHard™ 2898-MCG is very tough with excellent resistance to chipping and spalling. Deposits will retain their hardness and maintain a good cutting edge up to 1100°F (593°C). For maximum impact resistance and to avoid cracking in multi-layer deposits, a preheat of 550°F (288°C) is recommended. Use to overlay carbon, low alloy steel and manganese steel.
