AISI 4145H
It is a high-strength, chromium-molybdenum (chromoly) alloy steel specifically designed for applications requiring exceptional hardenability, toughness, and fatigue resistance.
Descriptions
1. Chemical Composition
AISI 4145H features a higher carbon content compared to AISI 4140, enhancing its strength and hardenability. Chromium and molybdenum improve wear resistance and high-temperature stability.
2. Mechanical Properties
AISI 4145H forgings achieve superior mechanical performance through heat treatment (e.g., quenching and tempering). Hardenability bands (H-code) ensure uniformity in large cross-sections.
3. Key Advantages
Controlled Hardenability: Uniform properties in thick sections (H-grade compliance).
High Fatigue Strength: Resists cyclic loading in drilling and mining equipment.
Wear Resistance: Suitable for abrasive environments.
4. Typical Product Names
Forged Drill Collars
Tool Joints for Drill Pipes
Heavy-Duty Gear Blanks
Turbine Rotor Shafts
High-Pressure Valve Bodies
