Chuck Metals, located in Pulau Ujong, Singapore, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, including Stainless Steel 317 Flat Bars. These bars are celebrated for their impressive durability and exceptional resistance to chemical corrosion, making them a go-to choice in various industries like chemical processing, marine applications, pulp and paper, and pharmaceuticals. Chuck Metals ensures that their products adhere to international standards, providing consistent quality, precise dimensions, and outstanding customer service across Singapore and Southeast Asia.
Stainless Steel 317 Flat Bar is a high-alloy austenitic stainless steel that features 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum of 0.08% carbon. The molybdenum content significantly boosts resistance to pitting, crevice corrosion, and aggressive chemical attacks, particularly in acidic and chloride-rich settings. In terms of mechanical properties, it boasts a tensile strength of about 75 ksi (515 MPa), a yield strength of around 30 ksi (205 MPa), and an elongation of 35–40%. This alloy also provides excellent weldability, formability, and retains strength even at high temperatures.

Stainless Steel 317 is primarily composed of iron, chromium (about 18-20%), nickel (11-15%), and molybdenum (3-4%). It also contains small amounts of manganese, silicon, and carbon, offering excellent resistance to corrosion, especially in acidic environments.
Yes, Stainless Steel 317 Flat Bar is highly resistant to corrosion due to its high chromium and molybdenum content. It performs exceptionally well in aggressive environments, including exposure to chlorides and acidic conditions, making it suitable for harsh applications.
Yes, Stainless Steel 317 Flat Bar can be welded easily. Its composition, including high nickel and chromium, allows for good weldability. However, proper welding techniques and preheating may be necessary to prevent cracking or distortion in some cases.
You’ll find Stainless Steel 317 Flat Bars commonly utilized in structural frameworks, brackets, supports, chemical tanks, heat exchangers, and marine components. Their flat shape makes them easy to work with, perfect for applications where stability, strength, and corrosion resistance are crucial. Industries trust 317 flat bars for their long-lasting performance, low maintenance requirements, and ability to withstand harsh chemical exposure and mechanical stress. This material is particularly sought after in environments that demand high performance and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
