Applications

CEWELD® ER 90 S-G (P92) is a high-temperature, creep-resistant, modified martensitic wire of type W Z CrMoWVNb 9 0.5 1.5 / ER90S-B92. The alloy T92/P92 is often used in the power generation industry for ultra-supercritical fossil fuel-fired power plant boilers and turbines; the alloy is also used in the chemical, oil and gas industries.

Properties

CEWELD® ER 90 S-G (P92) is commonly used at operating temperatures of up to 620°C. V, Nb and N additions give this “creep improved ferritic” (CSEF) alloy improved high temperature creep resistance compared to standard creep resistant CrMo alloys. Due to the controlled Mn+Ni content, the A C1 temperature is safely above 780ºC.
