What is WP91?
A Chrome- moly alloy metal with exceptional strength and temperature resistance is WP91. It is an improved ferritic because it is prepared for increased creep strength (CSEF). This metal is standardized at 1050 °C, air-cooled to 200 °C, and then heated to 760 °C to temper it. The primary cause of WP91's creep strength and durability is this process. WP91 denotes the metal's 9% chromium, 1% molybdenum, and vanadium makeup. The chromium boosts oxidation resistance and thermal strength. The molybdenum improves the elasticity, wear resistance, and high temperature creep strength.
