Heat-Resistant Casting Alloys / Wear-Resistant Casting Alloys
Heat-Resistant and Wear-Resistant Metal Materials for Extreme Environments
In the rapidly advancing refractory industry, particularly in steelmaking, the demand for metal materials capable of enduring high-temperature environments is paramount.
Leveraging decades of expertise and innovation in heat-resistant steel production, we have developed cutting-edge super heat-resistant alloys that deliver exceptional performance.
(Key properties: Wear resistance, oxidation resistance, corrosion resistance, creep strength, rigidity, and thermal shock resistance.)
In the manufacturing sector, production lines often involve the transportation of powders, fluids, and other raw materials, which inevitably leads to wear caused by impacts, sliding, and scratching.
Each type of wear requires tailored resistance, and our company excels in meeting these demands. Drawing on extensive knowledge of wear mechanisms accumulated by our R&D and manufacturing technology teams, we provide materials optimized to meet the specific needs of diverse industries.
