420 in CNC Machining
420 is a martensitic stainless steel with high strength and hardness. It is commonly used for cutlery and surgical instruments, and heat treatment can further increase its mechanical properties.
- High strength and hardness: 420 suits components that need elevated hardness and strength.
- Heat treatable: Heat treatment can increase its mechanical properties.
- Instrument applications: 420 is used for cutlery and surgical instruments.
Selection note: Stainless steel offers excellent corrosion resistance, strength, and easy cleaning. RapidDirect provides as-machined, electroplated, passivated, powder-coated, polished, and brushed surfaces.
