Product Description:
410 and 420 stainless steel forged fittings are high-strength and corrosion-resistant components designed for demanding industrial applications. Known for their excellent mechanical properties, these martensitic stainless steels offer superior hardness, wear resistance, and moderate corrosion resistance, making them suitable for a wide range of industries.
410 Stainless Steel
- General-purpose martensitic grade with good corrosion resistance and high strength.
- Easily hardened through heat treatment for improved wear resistance.
- Excellent for applications involving mild corrosion and high mechanical stress.
420 Stainless Steel
- Higher carbon content than 410, offering enhanced hardness and wear resistance.
- Commonly referred to as “cutlery grade” stainless steel.
- Provides moderate corrosion resistance in mild environments.
Key Features of 410/420 Stainless Steel Forged Fittings
- High Hardness: Exceptional wear and abrasion resistance.
- Corrosion Resistance: Moderate resistance to corrosion in mildly corrosive environments.
- Heat Treatable: Both grades can be hardened to enhance strength and wear resistance.
- Good Machinability: Easily fabricated with standard machining processes.
- Durable Performance: Suitable for high-stress applications.
Common Applications
- Petrochemical Industry: Piping systems exposed to mild corrosive agents and mechanical stress.
- Power Generation: High-temperature and pressure-resistant components.
