Product Description

42CMo4QT Seamless Tubes for the Machining Industry

Premium Alloy Steel for Demanding Applications

Steel grade 42CrMo4+QT – when failure is not an option. If you need a reliable, all-purpose alloy steel that can handle extreme loads, high stress, and long service life, 42CrMo4+QT is the proven choice. Engineered for demanding mechanical applications, this steel delivers the ideal combination of strength, toughness, and durability.

Key Advantages

High strength with excellent toughness, perfect for heavily loaded, safety-critical parts
Versatile "workhorse" material for a broad range of components
Proven performance in axles, transmission shafts, and gear wheels
Suitable for additional surface hardening for extra wear resistance
Reliable, stable properties for precise, repeatable machining results
Handles high static and dynamic loads with confidence
Reduces risk of premature wear, distortion, or failure
Supports longer service life and lower maintenance costs
Balanced combination of machinability and mechanical performance

Typical Applications

Axles and shafts (including transmission shafts)
Gear wheels, pinions, and couplings
Heavy-duty machine parts and drive components
High-load bolts and connecting elements
Parts requiring surface hardening for extra wear resistance

Performance Characteristics

Quenched and tempered (QT) condition for optimized mechanical properties
Excellent core strength with good toughness for fatigue resistance
Suitable for additional surface hardening to enhance wear resistance

Important Welding Note: 42CrMo4 is a steel that is difficult to weld. To ensure safety and preserve mechanical properties, always follow the material manufacturer's welding and pre-/post-heat treatment guidelines precisely.
