Nial Sheets and Plates is a well-respected manufacturer and supplier of Stainless Steel 405 Angles based in Houston, USA. They’re known for delivering top-notch structural products that are built for strength, formability, and resistance to oxidation. Stainless Steel 405 is a ferritic grade that stands out for its excellent weldability and lower hardening after welding, making it a great choice for structural and fabricated components. Nial ensures that these angles meet global standards, serving a variety of industries including power generation, automotive, petrochemical, and heat treatment. Their Stainless Steel 405 Angles are crafted with precision, guaranteeing reliable performance and a long service life, even in high-temperature settings.
These angles are primarily made of iron and chromium (11.5–14.5%), with added aluminum and a lower carbon content to boost oxidation resistance and reduce hardening during welding. This ferritic alloy offers moderate strength, with tensile strength ranging from 380 to 550 MPa and yield strength around 205 MPa. The aluminum addition enhances scaling resistance, making 405 a solid option for high-temperature applications. While it doesn’t harden through heat treatment, it responds well to cold working and forming.

Stainless steel 405 angle offers many advantages, including excellent resistance to oxidation and corrosion especially in high-temperature environments Highly durable, maintains strength and power even at high temperatures, and provides fit for applications in heat exchangers, industrial equipment and aerospace industries but does this Low carbon content reduces the risk of carbide precipitation, which adds to intergranular corrosion with increased ho resistance, the alloy also offers improved hardness and wear resistance compared to other stainless steel grades, providing longer lasting performance.
Stainless Steel 405 Angles find their place in various applications that require good oxidation resistance, moderate strength, and excellent weldability. In power plants, they’re used for turbine housings, ducting, and exhaust components. The automotive sector employs them in mufflers and heat shields. In construction and structural engineering, they act as support frames, brackets, and reinforcements. Their stability at elevated temperatures also makes them ideal for annealing boxes, furnace parts, and other thermal processing equipment. With reliable machinability and a lower risk of cracking during welding, these angles are a smart and cost-effective choice for industrial fabrication.
