Product Details

Product Description

Grade T/P92 is a ferritic-martensitic (9 % chromium, 1.75 % tungsten, 0.5 % molybdenum) steel micro-alloyed with vanadium and

niobium, and has controlled boron and nitrogen contents according to ASTM A 335, A 213 or to EN 10216-2 standard under the

designation X10CrWMoVNb9-2.

Grade T/P92 exhibits excellent elevated-temperature strength and creep behavior up to 600 °C - 620 °C. Its 9 % chromium content

offers better corrosion and oxidation resistance than grade 22. In addition, the reduced weight of boiler and piping components

resulting from the steel's superior performance compared with other standard steels allows higher resistance to thermal fatigue.

Compared with austenitic steels, grade T/P92 has higher heat transfer and lower thermal expansion coefficients.
