Premium Haynes 188 & 230 Fittings – High-Temp Flanges, Forged & Outlet Fittings – MSS SP-97, ASME B16.5/B16.11 Standards Haynes 188 and Haynes 230 are high-performance cobalt- and nickel-based superalloys engineered for extreme heat and oxidative environments. These alloys are widely used in aerospace, gas turbines, and heat exchanger applications due to their excellent resistance to high-temperature oxidation, thermal fatigue, and carburization. We supply a comprehensive range of industrial components in these materials, including buttweld fittings, forged flanges, and branch outlet fittings, precision-engineered for superior service in demanding thermal conditions. We offer Haynes 188 and Haynes 230 components in standard configurations like elbows, tees, reducers, caps, stub ends, socket weld & threaded fittings, and flanges such as WNRF, SORF, blind, and RTJ. Our branch outlet range includes Weldolets, Sockolets, and Threadolets. All products conform to international manufacturing standards like ASME B16.5, B16.9, B16.11, and MSS SP-97, ensuring seamless integration with global piping systems. Pressure classes supported range from 150# to 2500#, with sizes from ½” to 24” NB and wall thicknesses from SCH 10 to XXS. Haynes 188 offers exceptional resistance to oxidizing environments up to 1095°C (2000°F), along with good fabricability and weldability. Haynes 230, on the other hand, is known for its outstanding strength and stability at temperatures exceeding 1149°C (2100°F), along with superior oxidation resistance. These properties make both alloys ideal for use in combustion liners, afterburners, transition ducts, industrial furnaces, and reformer components in refineries and power plants. Our Haynes 188 and Haynes 230 products are manufactured under strict quality control protocols and are ISO 9001:2015 certified. We provide complete traceability and documentation, including EN 10204 3.1/3.2 MTC, NACE MR0175 compliance, ultrasonic testing, PMI, and hydrostatic reports. With ready stock, custom fabrication services, and a global distribution network, we ensure prompt delivery to critical industries across…
