Nestled in the heart of Kinshasa, Sadiki Metals has built a strong reputation as a trusted partner for industry, providing robust and reliable materials. We take particular pride in our Stainless Steel 317L Flat Bars, a product engineered for those challenging environments where ordinary steel simply won’t hold up. This isn’t just another piece of metal; it’s a testament to our commitment to supplying Congolese businesses with the high-performance materials needed to build a stronger, more resilient future for our community and beyond.
What truly sets our 317L flat bar apart is its sophisticated makeup. The alloy is enriched with higher levels of molybdenum and chromium, giving it a significant edge in resisting corrosion, especially against harsh chemicals and salty atmospheres. This low-carbon version also means it’s excellent for welding, as it minimizes the risk of damaging the material’s integrity at the seams. You can count on its strength and durability, making it a dependable choice for structural components that must endure demanding conditions without faltering.

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.
Because of its exceptional resistance to corrosion, you’ll find our 317L flat bar is indispensable in some of the toughest industrial settings. It’s the go-to material for constructing chemical processing equipment, large-scale ductwork and scrubbers in pollution control systems, and components for oil and gas refineries. Its reliability also makes it a perfect fit for architectural projects in coastal areas, where the salt air can be punishing, ensuring that structures not only look good but stand the test of time with minimal maintenance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
