Product Analysis
Material and process:
Aerosolized 440C stainless steel powder (C: 1.0%, Cr: 17%, Mo: 0.6%)
Hot isostatic pressing (HIP 1180 ° C/100MPa) achieves 99.98% density
Surface performance:
Vacuum quenching+cryogenic treatment, surface hardness HV600 ± 20 (ISO 6507)
CrN coating (3 μ m), friction coefficient ≤ 0.15 (ASTM G99)
Structural design:
Spiral groove silicon nitride ceramic particle reinforcement (increased wear resistance by 3 times)
