15NiCr1Mo12 Alloy Steel 15NiCr1Mo12 Round Bars

Product Description

Technical Overview

15NiCr1Mo12 is a high-performance Nickel-Chromium-Molybdenum alloy steel known for its exceptional toughness and core strength. It is primarily used for parts requiring high surface hardness after carburizing, combined with a very strong and ductile core to withstand heavy shock loads.

Key Specifications & Properties

Industrial Applications

Because of its high fatigue strength and resistance to wear, 15NiCr1Mo12 round bars are used for:

• Heavy-Duty Gearing: High-load gears, crown wheels, and pinions.

• Automotive & Aerospace: Critical drivetrain components and crankshafts.

• Mining & Drilling: Heavy-duty shafts and connecting rods subjected to extreme impact.

• Machine Tools: High-precision spindles and wear-resistant mechanical parts.

Features to Highlight in Your Listing

• Extreme Core Toughness: Unlike standard steels, this maintains high ductility even at very high strength levels.

• Superior Case Hardening: Ideal for carburizing to achieve a high-wear surface ($58-62 \text{ HRC}$).

• Shock Load Resistance: Specifically engineered to prevent brittle failure under sudden impact.

• Premium Machinability: When supplied in the annealed state, it allows for high-precision machining before final hardening.
