AISI 440C, 9Cr18Mo,Wear Resistance and Corrosion Resistance Plastic mould steel
9Cr18Mo may be a martensitic chrome steel with high carbon and Cr. It bears high hardness, heat resistance, tempering resistance, corrosion resistance and wonderful dimensional stability at elevated temperature. it's appropriate for plastic moulds needed high load, nice wear resistance and sensible corrosion resistance.
Chemical Composition of 9Cr18Mo (%):
| C | Si | Mn | Cr | Mo |
| 0.95~1.10 | ≤0.80 | ≤0.80 | 16.00~18.00 | 0.40-0.70 |
Standard specification of 9Cr18Mo:
AISI 440C, JIS SUS440C.
Characteristics of 9Cr18Mo:
AISI 440C, may be a high-chrome and Mo alloy wear resistance and corrosion resistance plastic mould steel with high hardness. The content of chrome within the steel reaches Sixteen Personality Factor Questionnaire or higher, superimposed with atomic number 42|metal} alloy element, so the steel has superior resistance to abrasion and corrosion. it's largely appropriate for electrical plastics, home appliances and plastic mould superimposed with flame retardation.
Delivery condition of 9Cr18Mo:
Annealed: ≤269HB
Specifications of 9Cr18Mo:
1. Size of flat bars: 10~130mm*200~410mm.
2. spherical bars: Φ10~Φ200mm.
3. Size of solid flat bars: 100~300mm.
Applications of 9Cr18Mo:
1. Electrical plastics and plastic mould superimposed with flame retardation.
2. appropriate for creating the molds for numerous medium or top-grade electrical switches, chargers and electrical kettle seat.
3. additionally used for creating the molds for plugs and inserts on laptop, camera and alternative preciseness instruments.
