Nestled in the heart of Kinshasa, Sadiki Metals stands as a trusted partner for industry, bringing reliable, high-quality materials to the local market. We take pride in supplying robust solutions for demanding projects, and our Stainless Steel 317 Flat Bar is a prime example. This particular grade is specifically chosen for its exceptional ability to withstand some of the toughest corrosive environments, making it an indispensable asset for engineers and fabricators across Congo who require durability and long-term performance from their materials.
The strength of the 317 flat bar comes from its sophisticated composition, which includes higher levels of chromium, nickel, and a significant addition of molybdenum. This specific blend gives it superior resistance to pitting and crevice corrosion, especially when faced with chlorides and acidic conditions. Mechanically, it offers excellent tensile strength and good ductility, allowing it to be fabricated into complex shapes without sacrificing its structural integrity, even in high-temperature service environments.

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.
Because of its robust nature, the Stainless Steel 317 Flat Bar is ideally suited for some of the most challenging applications. You will often find it forming the backbone of chemical processing equipment, components in pulp and paper mills, and critical parts within pollution control systems. Its reliability also makes it a preferred choice for architectural features in coastal areas, heat exchangers, and various vessels that handle aggressive chemicals, ensuring projects are built to last while minimizing maintenance needs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
