Nestled in the heart of Kinshasa, Sadiki Metals stands as a trusted partner for industry, dedicated to providing robust and reliable materials. We take pride in our role as a manufacturer and supplier of high-grade Stainless Steel 440C round bars and rods. Our focus is on delivering products that meet the rigorous demands of our clients, ensuring that every bar we produce supports the growth and precision required by modern engineering and manufacturing sectors right here in Congo and beyond.
The strength of 440C stainless steel comes from its high carbon content, which allows it to be hardened to exceptional levels. This composition, rich in chromium, gives the steel its notable resistance to corrosion and wear. Once properly heat-treated, it achieves impressive hardness, strength, and durability, making it a material that reliably maintains its edge and structural integrity even under significant stress and in challenging environments.

Yes, Stainless Steel 440C Round Bars/Rods can be used in cryogenic applications. Their high hardness and strength remain effective at low temperatures, making them suitable for use in cryogenic environments.
Yes, Stainless Steel 440C Round Bars/Rods require regular inspection to ensure their structural integrity, especially in high-stress applications, to detect any signs of wear, corrosion, or cracks over time.
Yes, Stainless Steel 431 Round Bars/Rods can be welded, although preheating and post-weld heat treatment are recommended to prevent cracking and maintain the material's mechanical properties.
You’ll find our 440C round bars and rods at work in critical applications where failure is not an option. They are essential for crafting high-performance components like precision ball bearings, valve parts, and moulds for injection moulding. The material’s excellent qualities also make it ideal for surgical instruments, cutting tools, and various parts within the aerospace and automotive industries, where a combination of hardness, corrosion resistance, and reliability is absolutely essential for success.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
