1.4923 / X22CrMoV12-1+QT2

Creep resisting steel 1 .4923 / X22CrMoV12-1+QT is very popular material for turbine, valve, and pumps producers.

According to norm EN 10269 is material produced in two variants QT1 and QT2. Difference is in mechanical properties:

QT1: Rp0,2 = min. 600Mpa, Rm = 800 – 950Mpa, KV min. 27J

QT2: Rp0,2 = min. 700Mpa, Rm = 900 – 1050Mpa, KV min. 20J

(QT2not conform with PED 2014/68EU requirement for KV min. 27J !!!)
