Hardened and tempered steel 43CrMo4 Round bar, Flat bar, Plate, Stocklist 43CrMo4 Properties from steelmaking, Hot forging & rolling, Heat treatment
ALLOY STEEL DATA SHEET - DIN 43CrMo4
MATERIAL CATEGORY: hardened and tempered steel
PRODUCT DESCRIPTION
The alloy is usually produced by EAF /VD /LF 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 annealed condition, or bright annealing specially.
Final heat treatment - heat treatment / QT
