X12CrNiMoV12-3, a martensitic Cr-Ni-Mo-V base Steel, Round bar 1.4938 flat bar, and forging plate, ESR & VAR technique, Blooming, Hot forging, Hot rolling, Heat treatment, Cold machined.
TECHNICAL DATASHEET - Grade X12CrNiMoV12-3
MATERIAL CATEGORY - High temperature high strength steel and superalloy
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / EAF 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 solution annealing condition.
Final heat treatment - heat treatment / Q + T + STR
