Processing Overview

Description: Case carburizing involves heating to 850-950°C to infiltrate carbon into a hardened layer (0.1-2mm deep), followed by quenching and tempering. The process involves carburizing, diffusion, and heat treatment, with a total duration of 4-20 hours.

Applicable Materials: Mild and medium carbon steels.

Visual Appearance: Slight surface discoloration (light gray or blue), with no noticeable grain in the hardened layer.

Advantage

High Surface Hardness: The hardened layer reaches HV 600-900, resisting wear.
Core Toughness: Maintains ductility within the core, resisting impact.
High Fatigue Resistance: Improves component life, suitable for gears and shafts.
Cost-Effectiveness: Achieves high performance using low-cost steel.
Dimensional Stability: A thin hardened layer allows for minimal tolerance variations.
Versatility: Suitable for mechanical and automotive components.

Precautions

Temperature Control: 850-950°C. Excessively high temperatures can lead to coarse grains. Test for carbon concentration.
Quenching Management: Rapid cooling to avoid cracks. Test for hardness distribution.
Surface Protection: Use an anti-carburizing mask to protect non-hardened areas.
Design Considerations: Plan for uniform wall thickness and avoid stress at sharp corners.
Quality Standards: Comply with ASTM A255, checking hardness and depth.
Safety Measures: Protect against high temperatures and carbon dust, and control exhaust gases.
