Nimonic PK33 nickel bar, Nimonic PK33 nickel round bar price, Nimonic PK33 manufacture

Alloy PK33 is a superalloy which is highly resistant to thermal shock and thermal fatigue. It also offers superb weldability, meaning it is often used to combustion chambers, jet pipes and reheat systems for high performance gas turbine engines. Alloy PK33 sheet fabrications are normally out into service after completion of the two-stage heat treatment process. This heat treatment is usually carried out in air. Alloy PK33 is often used in high strength applications at elevated temperatures, such as in gas turbine hot sections or enclosures for industrial furnace hot sections.
