What are the temperature ranges of box type tempering furnaces?

The temperature range of a box type tempering furnace varies depending on the material type, process requirements, and equipment design. Its coverage usually ranges from low to high temperatures, which can meet the heat treatment requirements of different industrial fields.

1. Material characteristics
Carbon steel/alloy steel: usually tempered at 500 ℃ -650 ℃ to balance hardness and toughness.
Aluminum alloy: Aging treatment at 150 ℃ -300 ℃ to improve strength and corrosion resistance.
Stainless steel: Tempered at 650 ℃ -850 ℃ to optimize corrosion resistance and mechanical properties.

2. Process requirements
Stress relief: Low temperature tempering (150 ℃ -300 ℃).
Adjust hardness: medium temperature tempering (300 ℃ -500 ℃).
Improve toughness: High temperature tempering (above 500 ℃).
Equipment capacity
Resistance furnace: up to 1200 ℃, suitable for tempering most metals.
Gas stove: can achieve higher temperatures (such as 1300 ℃), but the temperature control accuracy is slightly lower.

3. Special application temperature range
Low temperature tempering (<300 ℃) Applications: Precision parts, electronic components, aerospace components. Purpose: Minimize dimensional changes and maintain high hardness. Ultra high temperature tempering (>1000 ℃)
Applications: High temperature alloys, ceramic materials, powder metallurgy.
Purpose: To improve high-temperature performance, such as oxidation resistance and creep resistance.

4. Selection suggestions
Clarify process requirements: determine the required temperature range, heating rate, atmosphere requirements, etc.
Consider equipment performance: choose equipment with high temperature control accuracy and good temperature uniformity.
Evaluate economy: Select appropriate equipment specifications based on production volume and budget.
Pay attention to safety: Ensure that the equipment has safety functions such as over temperature protection and leakage protection.

5. Summary
The temperature range of the box type tempering furnace is wide, from 150 ℃ to 1200 ℃ or even higher. The specific selection should be determined comprehensively based on the material type, process requirements, and equipment capabilities. Reasonable selection of temperature range can effectively optimize material properties, improve product quality and production efficiency.
