Therma 4622Nb™ is available as cold rolled coil and sheets and in thicknesses of 0.5 – 2 mm with widths up to 1250 mm.
Therma 4622Nb™ offers a wide performance range thanks to its unique characteristics. Discover the benefits.
Performance in high temperatures: good stability against thermal fatigue and excellent high temperature creep resistance.
Excellent cost stability compared to Ni-alloyed austenitic grades and Mo-alloyed acid proof grades.
Corrosion resistance comparable to common austenitic grades 304 and 304L.
Thanks to the good material characteristics, all forming methods can be used.
Low risk of sensitization owing to stabilization. Less distortion than in austenitic grades due to higher heat transfer.
Lower work hardening than austenitic grades, enabling faster machining times and longer tooling life.
Introduced in early 2024, Therma 4622Nb™ is is ideal for price-sensitive applications that require excellent high-temperature properties and good corrosion resistance combined with good weldability, formability, and machinability. Find out more in our article.
