AISI 4330v modified steel from USA

AISI 4330v modified steel is a versatile quenched and tempered steel that is characterized by its high toughness and strength and has excellent notched bar impact values at -40°C. These properties are maintained over large cross-sectional dimensions (thicknesses) by the addition of vanadium.

International identifiers

ASTM A646/A646M-06(2011), 1.6932

Applications:

The material AISI 4330 is preferably used in mechanical engineering (high-strength parts) and in the oil and gas sector.

Properties:

Characteristics

Weldability:
AISI 4330V mod. is very difficult to weld and is therefore not suitable for welded constructions. If welding is unavoidable, a preheating temperature of 400°C and a post-weld heat treatment at 600°C is recommended, or even better a renewed quenching and tempering.
