With a strong focus on excellence, innovation, and reliability, Gabriel crafts precision-engineered tube fittings that are built to handle the tough demands of various industrial sectors. The company employs cutting-edge manufacturing techniques and rigorous quality control measures to ensure that each fitting performs at its best, even in extreme conditions. Catering to both domestic and international markets, Gabriel Tube Fittings has built a solid reputation for providing corrosion-resistant and high-strength solutions tailored to the needs of industries like oil & gas, chemical, marine, and power generation.
Super Duplex Steel S32750 Tube Fittings are crafted from a high-alloy austenitic-ferritic stainless steel. Their typical chemical makeup includes Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (0.24–0.32%), with Iron as the base. This unique composition gives them outstanding resistance to pitting, stress corrosion cracking, and crevice corrosion. On the mechanical side, S32750 boasts impressive strength, with a minimum tensile strength of 795 MPa and a yield strength of 550 MPa, along with good ductility and impact toughness. These characteristics make the fittings perfect for challenging environments where high pressure and aggressive chemical exposure are the norms.
