Operating from the heart of Kinshasa, Sadiki Metals is a trusted partner for robust industrial materials. We take pride in manufacturing and supplying high-grade Stainless Steel 446 rectangular bars, engineered specifically for the demanding conditions found across Congo. Our commitment is to deliver not just a product, but a reliable solution that stands up to intense heat and corrosion, ensuring the longevity and success of your most critical projects in construction and heavy industry.
Stainless Steel 446 earns its reputation through a unique composition, being a high-chromium ferritic alloy without nickel. This blend gives it exceptional resistance to scaling at temperatures up to 1100°C, outperforming many other types. Mechanically, these bars are known for their good strength and impressive ductility, allowing them to be fabricated into various shapes while maintaining their structural integrity under significant thermal stress.

When selecting Stainless Steel 446 Rectangular Bars, consider factors like temperature resistance, corrosion resistance, and the specific environmental conditions. Additionally, ensure compatibility with the required mechanical properties and fabrication needs.
Stainless Steel 446 Rectangular Bars are not ideal for cryogenic applications due to their reduced toughness at low temperatures. For cryogenic use, materials with better low-temperature properties, like austenitic stainless steels, are recommended.
Stainless Steel 446 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent high corrosion resistance. However, in highly aggressive environments, coatings may be used for added protection.
You’ll find Sadiki Metals’ 446 rectangular bars are indispensable in environments where extreme heat is a constant challenge. They are the go-to material for constructing vital furnace parts, heat exchangers, and high-temperature industrial furnaces. Beyond thermal applications, their excellent corrosion resistance makes them a solid choice for chemical processing equipment and architectural elements in coastal areas, proving their versatility and durability across a wide range of demanding sectors.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
