410 Stainless Steel Round Bar (UNS S41000)
410 Stainless Steel Round Bar is a martensitic stainless steel grade offering a strong combination of moderate corrosion resistance, high strength, and good wear resistance. Identified by UNS S41000, this alloy can be hardened by heat treatment, making it suitable for applications requiring strength and durability in mildly corrosive environments.
It is widely used in automotive, oil & gas, power generation, and industrial machinery applications.
Key Features
- Good corrosion resistance in mild atmospheres and industrial environments
- High strength and hardness after heat treatment
- Excellent wear and abrasion resistance
- Good machinability in annealed condition
- Magnetic in all conditions
- Cost-effective martensitic stainless steel grade
