Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their high-performance offerings are Stainless Steel 440C Pipes, engineered for applications that demand exceptional hardness, wear resistance, and corrosion resistance. Known for their precision and durability, these pipes are ideal for industrial, automotive, and mechanical systems exposed to high stress or friction. At Walid Stainless, each pipe is crafted with meticulous attention to quality and undergoes strict control standards, ensuring consistent performance. Clients rely on 440C Pipes for reliable, long-lasting solutions where strength and precision are essential.
Stainless Steel 440C Pipes are made from a high-carbon martensitic stainless steel alloy containing approximately 16–18% chromium. This composition gives them excellent hardness, wear resistance, and moderate corrosion resistance. The alloy is heat-treatable, achieving tensile strength of 760–1,000 MPa and hardness up to 58–60 HRC. These properties ensure durability, dimensional stability, and resistance to mechanical stress. The pipes’ high-carbon martensitic structure allows them to maintain performance in demanding environments, making them suitable for high-stress and high-wear industrial or mechanical applications.
