Heat treatment is essential for unlocking the full potential of martensitic stainless steel.

The process usually involves three stages:

1. Austenitizing: Heating the steel to 950–1050°C to form austenite.

2. Quenching: Rapid cooling in air or oil to form hard martensite.

3. Tempering: Reheating to 150–500°C to reduce brittleness while maintaining strength.

    These steps allow manufacturers to tailor the hardness and toughness of the steel to match specific application requirements.

For example, knives used in tropical climates (e.g., Southeast Asia) may benefit from a tempered finish that resists both wear and corrosion.

Our factory offers in-house heat treatment and can meet diverse technical specifications for global clients.
