Promispecialยฎย high-temperature bearing steel is meticulously engineered to excel in extreme conditions, featuring strong carbide-forming elements such as chromium and molybdenum. These additions impart exceptional high-temperature hardness, wear resistance, contact fatigue strength, oxidation resistance, and dimensional stability. Capable of operating in environments ranging from 200ยฐC to 430ยฐC, this steel is ideal for demanding applications in metallurgy, aerospace, automotive, and industrial heating equipment.
High-Temperature Hardness: Through specialized alloy design and heat treatment processes, our steel maintains a hardness of HRC 62 or above, even at temperatures up to 400ยฐC.
Wear Resistance at High Temperatures:ย The addition of carbide-forming elements creates a hard, wear-resistant surface that significantly enhances performance under high-temperature conditions.
Contact Fatigue Strength:ย Optimized chemical composition and microstructure reduce the risk of cracking under cyclic loads, increasing the steel’s contact fatigue strength.
Oxidation Resistance:ย High chromium content provides excellent resistance to oxidation, preventing surface degradation in high-temperature environments.
Dimensional Stability:ย Our unique heat treatment ensures that the steel retains its precise dimensions and stability, even after prolonged exposure to high temperatures.
Alloy Design: Carefully selected alloying elements and precise ratios are used to form a uniformly distributed carbide phase, essential for superior high-temperature performance.
Heat Treatment Process:ย Custom quenching and tempering procedures are employed to optimize the material’s mechanical properties and microstructure, ensuring peak performance.
Precision Manufacturing:ย Every piece of high-temperature bearing steel undergoes precise machining, ensuring minimal tolerances and exceptional surface finish.
Aerospace:ย Essential for high-temperature bearings in aircraft engines and spacecraft, where reliability and performance are critical.
Automation & Machinery Manufacturing:ย Ideal for industrial robots and precision machinery that operate in high-temperature environments.
Energy Industry:ย Plays a crucial role in high-temperature, high-pressure applications in oil drilling and power generation equipment.
