Processing Overview

Description: Through-hardening is achieved by heating the metal to 900-1200°C and quenching it to room temperature or in oil, resulting in a uniform hardened layer (full-depth) with a hardness of HV 500-700. The process includes preheating, quenching, and tempering, with a total time of 2-6 hours.

Applicable Materials: Medium-carbon steel, high-carbon steel, and alloy steel.

Visual Appearance: The surface may show quenching cracks or oxidized color, but no noticeable grain.

Advantage

Uniform hardness: Hardened across the entire cross-section, resisting wear and deformation.
High strength: Suitable for structural components subject to high loads.
High fatigue resistance: Increases component life and reduces fatigue fractures.
Cost-effectiveness: A single process covers the entire part, eliminating the need for localized treatment.
Dimensional stability: Minor variations require post-processing for correction.
Versatility: Suitable for molds and tool steels.

Precautions

Temperature Control: 900-1200°C. Excessively high temperatures will result in coarse grains; test melting point.
Quenching Medium: Oil or water cooling, test for deformation risk.
Tempering Optimization: Reduce brittleness, control temperature between 150-300°C.
Design Considerations: Plan for uniform wall thickness and avoid thin-walled areas.
Quality Standards: Comply with ASTM A29, checking hardness and depth.
Safety Measures: Protect against high temperatures and quenching splash, and control waste fluids.
