Material matrix: Matching extreme load-bearing missions

Four Core Alchemy Techniques

▍ Defect-Free Pure Steel

Oxygen content ≤ 6ppm (internationally leading ≤ 12ppm)

TiN inclusion size ≤ 3μm (ESEM analysis)

Carbide banding ≤ Grade 1 (GB/T 18254 standard)

Nanostructure strengthening and toughening

Triple heat treatment process:

Generation failed, ask in a different way

➜ Impact toughness increased by 50% (AKU ≥ 40J)

➜ Wear resistance triples ISO 683 standards

Micro-deformation control technology

Heat treatment deformation <0.03% (Φ50mm sample)

➢ Precision bearing grinding allowance reduced to 0.1mm

➢ Component assembly accuracy improved to P4/P2 level

Corrosion fatigue terminator

S-N curve slope increased by 2.3 times

▫ Fatigue limit retention rate ≥ 85% in 3.5% NaCl solution

▫ Lifespan in 300°C hot oil environment is four times that of ordinary materials

The value transition from bars to components

Full-process intelligent manufacturing capabilities:

Bar precision forging → CNC turning → Vacuum heat treatment → Ultra-fine grinding → Laser coding and tracking

Typical end products:

🚗 Three-in-one bearing for new energy vehicles: Quietness level ≤ 18dB (at 1000rpm)

🚢 Spherical bearing for deep-sea robots: Pressure-resistant up to 6000 meters, no leakage

🚀 Cross bearing for harmonic reducers: Backlash ≤ 0.3 arc minutes

Quality Control System: Redefining the Boundary of Reliability

Control Dimensions: Industry Standards, Meixinchang Commitment

Ingredient Purity: [O] ≤ 12ppm, [O] ≤ 6ppm

Heat Treatment Uniformity: Hardness Difference ≤ 3HRC, Hardness Difference ≤ 1HRC
