Chuck Metals, located in Pulau Ujong, Singapore, stands out as a top manufacturer and supplier of high-quality stainless steel products, including the Stainless Steel 317L Flat Bar. Renowned for their commitment to quality and precision, Chuck Metals caters to a diverse array of industries such as chemical processing, pharmaceuticals, marine engineering, and pulp and paper. Their 317L flat bars are crafted to meet international standards, ensuring exceptional corrosion resistance and mechanical reliability. With a reputation for prompt delivery, technical know-how, and a solid regional presence, Chuck Metals has become a go-to stainless steel supplier across Singapore and Southeast Asia.
The Stainless Steel 317L Flat Bar is a low-carbon, molybdenum-rich austenitic stainless steel alloy that features chromium (18–20%), nickel (11–15%), molybdenum (3–4%), and a carbon content capped at 0.03%. This unique composition enhances its resistance to pitting, crevice corrosion, and chemical attacks, particularly in acidic and chloride-laden environments. In terms of mechanical properties, it boasts a tensile strength of about 75 ksi (515 MPa), a yield strength close to 30 ksi (205 MPa), and an elongation rate of 35–40%. The alloy is also known for its excellent weldability, forming capabilities, and resistance to intergranular corrosion post-welding.

Stainless Steel 317L is primarily composed of iron, with high levels of chromium (18-20%) and nickel (11-15%), along with molybdenum (3-4%) for enhanced corrosion resistance. It also contains small amounts of carbon, manganese, silicon, and phosphorus.
Yes, Stainless Steel 317L Flat Bar is highly resistant to corrosion, especially in harsh environments. Its high chromium, nickel, and molybdenum content enhances resistance to pitting, crevice corrosion, and general oxidation, making it ideal for chemical and marine applications.
Yes, Stainless Steel 317L Flat Bar can be welded easily using standard welding techniques such as TIG, MIG, and SMAW. Its low carbon content minimizes carbide precipitation during welding, ensuring strong joints and excellent corrosion resistance in the weld area.
Stainless Steel 317L Flat Bars find extensive use in structural supports, frameworks, brackets, flanges, and various applications that demand corrosion resistance in tough industrial settings. Their flat design makes them easy to fabricate and install in tanks, pressure vessels, marine structures, and chemical handling systems. Thanks to its outstanding resistance to sulfuric acid and other harsh compounds, 317L is often the material of choice for critical components in the chemical, marine, and wastewater treatment sectors, where durability and reliability are paramount.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
