High room and elevated temperature strength, High notch tolerance.
Thermal expansion coefficients compatible with low alloy steel turbine casing materials.
Lower design and operating risks
Simplified design for bolting configuration compared with martensitic steels or high nickel alloys.
Proven performance in long-term service.
Extensive database of long term, high temperature test results.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the annealed condition, or bright annealing specially.
Final heat treatment - Quenched and tempered.
