Chuck Metals, based in Pulau Ujong, Singapore, is a well-respected manufacturer and supplier of high-quality stainless steel products, including Stainless Steel 317 Rectangular Bars. These bars are designed to perform reliably in extremely corrosive and chemically aggressive settings. Chuck Metals caters to various industries, such as chemical processing, pharmaceuticals, pulp and paper, and marine engineering. The company is known for providing materials that meet international standards, along with dependable service, technical know-how, and prompt deliveries throughout Singapore and Southeast Asia.
Stainless Steel 317 Rectangular Bars are high-alloy austenitic stainless steels, featuring around 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a carbon content of up to 0.08%. This unique alloy offers exceptional resistance to pitting and crevice corrosion, especially in environments rich in chlorides and acids. In terms of mechanical properties, these bars boast a tensile strength of about 75 ksi (515 MPa), a yield strength of roughly 30 ksi (205 MPa), and an elongation of 35–40%. The alloy retains its structural integrity even at elevated temperatures and provides good formability and weldability.

Stainless Steel 317 Rectangular Bars generally offer excellent corrosion resistance due to their alloy composition, but additional protective coatings may be beneficial in highly aggressive environments. For most applications, coatings are not necessary unless exposed to extreme conditions.
Choose Stainless Steel 317 Rectangular Bars based on factors like required corrosion resistance, strength, and the specific environmental conditions. Ensure the dimensions and grades meet the mechanical and chemical requirements of your application.
Yes, Stainless Steel 317 Rectangular Bars can be welded using standard welding techniques like TIG and MIG. However, proper heat control is essential to prevent carbide precipitation and maintain corrosion resistance.
You’ll often find Stainless Steel 317 Rectangular Bars being used in the construction of chemical tanks, heat exchangers, structural supports, and marine equipment. Their flat, rectangular shape makes them perfect for load-bearing applications, frames, and brackets where both strength and corrosion resistance are crucial. Industries favor 317 for its long-lasting service life, outstanding performance in corrosive conditions, and ease of fabrication. It’s particularly valued in operations that demand reliable materials capable of withstanding harsh chemicals, high temperatures, and mechanical stress.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
