DIN EN 10083-3 hardened and tempered steel 30CrMoV9, Chromium-Molybdenum-Vanadium Steel, 1.7707 round bar, flat bar, shaft, and plate, Heat treatment
MATERIAL DATA SHEET - Grade 30CrMoV9
MATERIAL CATEGORY: hardened and tempered steel
STOCK LIST & INVENTORY on hand - Round bar Dia. 25 ~ 230mm
PRODUCT DESCRIPTION
Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness.
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
