DIN EN 10083-2/3 (2006) of Steel 1.7043 Round bar, plate, forgings 38Cr4 ESR, blooming, forging, rolling, heat treatment, straightened, ultrasonic test, cold working & machined.
Official Test Certificate: issued by TUV - SGS - BV
TECHNICAL SPECIFICATION DATASHEET - DIN 38Cr4 / W-Nr 1.7043
MATERIAL CATEGORY: Flame and high-frequency heating surface hardening 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
Final heat treatment - heat treatment / QT
