Ashraf Nickel Alloys stands out as a reliable manufacturer and supplier of Hastelloy Valves in Riyadh, Saudi Arabia, providing expertly crafted flow control solutions designed for the toughest industrial settings. Hastelloy, a superalloy made from nickel, molybdenum, and chromium, is famous for its remarkable resistance to corrosion from strong oxidizers, reducing agents, and harsh acidic environments. Our valves are constructed to meet ASTM, ASME, and API standards, guaranteeing their reliability and durability across sectors like chemical processing, oil and gas, marine, and power generation. We offer a variety of valve types, including ball, gate, globe, check, and butterfly valves, all tailored to manage aggressive fluids and gases. Custom sizing and pressure ratings are available to fulfill specific project needs.
Hastelloy valves are mainly made up of nickel (around 58%), molybdenum (15–30%), and chromium (12–23%), along with trace amounts of iron, cobalt, tungsten, and manganese. This unique alloy provides exceptional resistance to oxidation, pitting, and stress corrosion cracking. Hastelloy boasts a tensile strength ranging from 690 to 760 MPa and a yield strength between 275 and 365 MPa, ensuring toughness in high-temperature and high-pressure situations. Its outstanding metallurgical stability guarantees a long service life, even when exposed to aggressive chemicals like hydrochloric acid, sulfuric acid, and chlorine compounds. With excellent weldability, formability, and impact resistance, Hastelloy valves are the go-to choice for critical flow control in extreme conditions.
