Decoding the performance of High Chromium Steel in Extreme Thermal Environments
High Chromium (Cr) steel castings represent the pinnacle of material science for applications exceeding 800°C. At JUNLONG Machinery Co., Ltd., we define heat resistance not just by the melting point, but by the material's ability to maintain tensile strength, creep resistance, and oxidation stability under cyclic thermal loading. High chromium content (typically 12% to 30%) creates a dense, protective Cr2O3 oxide layer on the surface, which prevents further atmospheric penetration and internal degradation.
Our engineering team specializes in the microstructural optimization of alloy steel and stainless steel. By strictly controlling the carbon-to-chromium ratio and introducing trace elements like Nickel (Ni), Molybdenum (Mo), and Nitrogen (N), we ensure that our castings resist "thermal fatigue"—the primary cause of failure in industrial furnaces and engine components. This expertise is why we have grown from our 2014 foundation to an annual capacity of 20,000 tons of precision parts.
Founded in 2014 in Weifang, Shandong, our facility covers 60,000 square meters. We are not just a foundry; we are an integrated high-tech supplier that merges lost wax investment casting with deep CNC machining. Our mission is to provide global industry leaders—from the US to Germany—with components that survive where others fail.
