At S R Thermal, we understand that the final stage of heat treatment is often the most critical. Our Low-Temperature Tempering Furnaces are engineered to provide the precise thermal stability required to relieve internal stresses and achieve the perfect balance of hardness and toughness in your components.
Designed for processes typically ranging from 150°C to 400°C, our furnaces ensure that your high-carbon steels and alloyed parts meet the most demanding industrial standards.
Why Choose S R Thermal Tempering Solutions?
Low-temperature tempering (also known as "stress relieving") is vital to prevent cracking and improve the ductility of quenched parts. S R Thermal equipment stands out through:
Superior Temperature Uniformity: We utilize advanced high-velocity air circulation systems to ensure every part in the batch reaches the exact same temperature.
Precision PID Control: Our digital control systems eliminate "overshoot," protecting your parts from losing too much hardness.
Energy Efficiency: Optimized high-grade insulation (ceramic fiber/mineral wool) ensures maximum heat retention and lower operational costs.
Heavy-Duty Construction: Built for the industrial floor, our furnaces feature rugged outer shells and corrosion-resistant interiors.
