Khaled Stainless, based in Cairo, Egypt, specializes in providing top-notch Stainless Steel 904L pipes that are perfect for environments rich in corrosive elements and chlorides. These pipes are crafted from certified 904L alloy and come in both seamless and welded varieties. They undergo rigorous dimensional, hydrostatic, and non-destructive testing to ensure quality. Known for its fully austenitic, super-alloyed composition, Stainless Steel 904L boasts remarkable resistance to pitting, crevice corrosion, and strong acids. Khaled Stainless offers standard schedules, custom wall thicknesses, polished finishes, and cut-to-length services. Each delivery includes comprehensive mill test certificates and traceability, catering to industries like chemical, marine, pharmaceutical, desalination, and high-end processes that demand long-lasting corrosion resistance.
Stainless Steel 904L is made up of about 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1–2% copper, with a very low carbon content (≤0.02%). This super-austenitic blend provides exceptional resistance to chlorides, sulfuric acid, seawater, and both reducing and oxidizing environments. Its mechanical properties are impressive, featuring a tensile strength of around 490–690 MPa, yield strength of approximately 220–280 MPa, elongation greater than 35%, and hardness ranging from 150 to 190 HB in the annealed state. 904L maintains its toughness at both low and high temperatures and outperforms 316L or 317L in resisting stress corrosion cracking. All pipes come with Material Test Certificates (MTCs) and optional Non-Destructive Testing (NDT) results.
