We’re well-known for our dedication to quality, precision engineering, and adhering to industry-leading standards. Our products serve a variety of sectors, such as aerospace, chemical processing, and high-temperature industries. Designed to endure extreme conditions, our Hastelloy W Pipes offer remarkable resistance to heat, corrosion, and mechanical stress. With state-of-the-art manufacturing facilities and rigorous quality control, Maria Pipes and Tubes provides dependable, high-performance solutions that meet both global standards and specific customer needs, both in Malaysia and beyond.
Hastelloy W Pipes are crafted from a solid-solution-strengthened alloy, primarily made up of nickel (Ni) and molybdenum (Mo), along with iron (Fe), chromium (Cr), cobalt (Co), and tungsten (W). The typical composition includes: Nickel (balance), Molybdenum (~5–6%), Iron (~2–5%), Chromium (~4–7%), and Tungsten (~4–5%). This carefully balanced mix ensures excellent weldability and high-temperature strength while effectively resisting oxidation and corrosion. The alloy’s chemical stability under extreme thermal conditions makes Hastelloy W a perfect choice for critical applications, such as aerospace welding and high-performance chemical reactors.
