C: 0.3–0.6, Cr: 18–24, Mn: 12–18, N: 0.2–0.4, Si ≤1.5, S ≤0.05, P ≤0.06

• Long-term service temperature: 800–1050℃
• Stable austenitic matrix reinforced by nitrogen element
• Excellent cyclic thermal shock resistance, withstand rapid heating & cooling without cracking
• Good high-temperature creep strength, resist permanent deformation under long-term heavy load

1. Cr-Mn-N composite alloy formula replaces high nickel heat-resistant steel, lower cost while maintaining premium thermal shock performance
2. Nitrogen element stabilizes high-temperature microstructure, effectively restrain surface oxidation and scaling at furnace working temperature
3. Strong anti-fatigue performance for frequent charging & discharging temperature fluctuation cycles
4. Optimized plate structure with reasonable rib reinforcement, improve load capacity and reduce thermal deformation
5. Dense casting structure with few internal defects, avoid premature fracture under long-term furnace operation

Furnace base plates, furnace trays, charging racks, support brackets, heat-resistant fixture castings made of CrMnN alloy

1. Mature CrMnN alloy smelting and homogenization heat treatment process
2. Rich experience manufacturing bearing castings for various heat treatment furnaces
3. Strict full-process quality inspection to guarantee thermal stability and anti-cracking performance
4. Stable bulk supply for heat treatment, metallurgy and machinery manufacturing factories
