At Louis Metals, we take pride in being a top supplier and manufacturer of stainless steel products right here in Houston, USA. Our Stainless Steel 430F Bars and Rods are crafted for outstanding machinability and corrosion resistance. This particular grade, 430F, is a free-machining ferritic stainless steel that’s been specially designed for quick and efficient production on automatic machining equipment. We offer a variety of sizes and finishes for our 430F bars and rods, making them perfect for precision-engineered parts across various industries. With a reputation for reliable performance and easy machining, our 430F products adhere to strict quality and dimensional standards, making them a great fit for high-volume manufacturing settings.
When it comes to composition and mechanical properties, our Stainless Steel 430F Bars and Rods primarily consist of 16–18% chromium, with a touch of sulfur (0.15–0.35%) to boost machinability. This grade has a very low carbon content (max 0.12%) and isn’t hardenable through heat treatment. In terms of mechanical properties, you can expect a typical tensile strength of 500–750 MPa and a yield strength of around 350 MPa. The Brinell hardness falls between 170–200 HB. 430F offers solid corrosion resistance in mildly corrosive environments and excels in machinability, making it a top choice for precision-turned components. Plus, it maintains good dimensional stability and surface finish after machining.

Stainless Steel 430F Bars and Rods shine in applications where excellent machinability and moderate corrosion resistance are key. These bars are frequently used to manufacture automatic screw machine parts, fasteners, bushings, gears, valve components, and shafts. In industries like automotive, appliance, and electronics, 430F is a go-to material for producing high-volume, close-tolerance components with smooth surface finishes. Its non-hardenable nature and reliable performance during machining make it a favorite for CNC operations. At Louis Metals, we’re committed to delivering quality products that meet your needs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
