Their Stainless Steel 348/348H Forged Fittings are designed for exceptional performance, durability, and resistance to corrosion, even in high-temperature and challenging environments. Produced under rigorous quality control and adhering to international standards, these fittings guarantee reliable, leak-proof connections in critical piping systems. MERIH STAINLESS prioritizes precision, material integrity, and prompt delivery, making their 348/348H Forged Fittings perfect for applications in power generation, petrochemical, chemical processing, and aerospace industries where high-temperature stability and long-term reliability are crucial.
Stainless Steel 348/348H Forged Fittings are crafted from stabilized austenitic stainless steel, which includes 20–25% chromium, 20–25% nickel, 0.04–0.10% carbon, along with small amounts of titanium, manganese, and silicon for stabilization. This unique composition provides outstanding resistance to oxidation, scaling, and thermal creep at high temperatures. In terms of mechanical properties, these fittings boast a tensile strength exceeding 515 MPa, a yield strength around 205 MPa, and excellent creep rupture resistance. Their high-temperature strength, toughness, and corrosion resistance make them ideal for critical piping applications in harsh chemical, thermal, and industrial settings.
