Product Description:
410 and 420 stainless steel tubes are martensitic stainless steels known for their excellent mechanical properties, moderate corrosion resistance, and high hardness after heat treatment. These grades are widely used in applications requiring strength, wear resistance, and moderate resistance to corrosion.
410 Stainless Steel Tubes
Grade 410 is a martensitic stainless steel that provides high strength, excellent wear resistance, and moderate corrosion resistance. It is heat-treatable, making it suitable for applications that require high hardness and durability.
Key Features
- Heat Treatable: Can achieve high hardness and strength through heat treatment.
- Moderate Corrosion Resistance: Performs well in mildly corrosive environments.
- Good Machinability: Easy to machine in the annealed condition.
- Excellent Wear Resistance: Ideal for applications involving friction or abrasion.
Applications
- Valves and pump components
- Cutlery and kitchen utensils
- Fasteners and bolts
- Shafts and spindles
- Petrochemical and marine equipment
420 Stainless Steel Tubes
Grade 420 is a higher carbon martensitic stainless steel that offers excellent hardness and improved corrosion resistance compared to 410. It is widely used in applications requiring high strength and a polished finish.
Key Features
- High Hardness: Achieves a mirror-like finish after polishing and heat treatment.
- Improved Corrosion Resistance: Superior to 410, especially in moderately corrosive environments.
- High Wear Resistance: Performs well in applications involving abrasion or high friction.
- Ease of Fabrication: Can be welded and machined with proper techniques.
Applications
- Surgical instruments
- Cutlery and knives
- Springs and washers
- Industrial machinery components
- Automotive parts and tools
