Product Description

Material Overview

15CrMoV6 (Werkstoff-Nr. 1.7734) is a low-carbon, high-strength chromium-molybdenum-vanadium aerospace alloy steel. It is identical in composition and performance to the French 15CDV6 specification. Renowned for its exceptional yield-to-tensile ratio, toughness, and fatigue resistance, 15CrMoV6 is especially valued for its outstanding weldabilityretaining high mechanical strength in welded joints without requiring complex pre-heating or post-weld heat treatment.
