430F Stainless Steel – Free Machining Stainless Steel
ASTM A-582, QQ-S-764B | UNS#: S43020
At Midland Bright Steels, we supply 430F Stainless Steel, a high-quality, free-machining stainless steel that offers excellent performance across a variety of industries. As a modified version of 430 Stainless Steel, 430F is specially enhanced for machining efficiency, making it an excellent choice for precision-engineered components.
This chromium-based stainless steel contains small but crucial amounts of manganese, silicon, carbon, phosphorus, sulfur, and molybdenum, contributing to its enhanced machinability while retaining the corrosion resistance and strength associated with the 400 series.
Key Features & Benefits
Superior Machinability – Designed specifically for high-speed machining applications, reducing tool wear and improving efficiency.
Magnetic Properties – 430F is ferritic, making it highly magnetic and suitable for solenoid and electromagnetic applications.
Corrosion & Oxidation Resistance – Provides moderate resistance to corrosion and oxidation, particularly in dry and mildly corrosive environments.
Good Mechanical Strength – Offers a balance of toughness and hardness, making it suitable for both structural and mechanical components.
Common Applications
430F Stainless Steel is widely used in industries requiring precision-machined parts with high wear resistance. Common applications include:
- Solenoids – Certified as “solenoid quality,” making it a preferred choice in electromagnetic systems.
- Valves & Fasteners – Ideal for producing high-strength, corrosion-resistant threaded components.
- Surgical Equipment – Used in certain medical and surgical instruments where machinability is critical.
- Threaded Bars & Pins – Excellent for industrial fastening solutions requiring durability and strength.
- Hinges – Used in both industrial and commercial hinge applications due to its strength and wear resistance.
- Combustion Chamber Linings – Suitable for high-temperature environments where moderate oxidation resistance is required.
