X12CrNiMoV12-3, a martensitic Cr-Ni-Mo-V base steel, round bar 1.4938 flat bar, and forging plate, ESR & VAR technique, gas turbine parts processing, heat treated
TECHNICAL DATA SHEET - X12CrNiMoV12-3
MATERIAL CATEGORY - high temperature high strength steel and superalloy
PRODUCT DESCRIPTION
X12CrNiMoV12-3 & 1.4938 is usually produced by AOD / VOD followed by electroslag refining (ESR) if necessary for special purpose. 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 annealing condition.
Final heat treatment - Quenched + tempered + STR
MATERIAL SPECIFICATIONS - DIN 17742, 17460, 17480, DIN EN 103021, 10296, 10095 (2002/1999)
