Uday Flanges is a reputable manufacturer and supplier of 16Mo3 Flanges based inDubai, UAE. They provide top-notch flanges designed for high-temperature and high-pressure applications. These flanges are commonly found in power plants, refineries, and chemical processing facilities, thanks to their outstanding mechanical properties and ability to resist thermal stress. Crafted in line with EN and DIN standards, Uday Flanges’ 16Mo3 flanges are celebrated for their durability, weldability, and dependable performance in high-temperature settings, particularly in equipment like boilers, heat exchangers, and pressure vessels.
The 16Mo3 grade is a low-alloy steel that features molybdenum as its main alloying element (around 0.3%), which boosts its strength and creep resistance when exposed to high temperatures. It generally provides a tensile strength ranging from 440 to 590 MPa, a yield strength of about 220 MPa, and excellent workability. These flanges maintain their mechanical stability even at temperatures reaching 500°C. Additionally, they contain trace amounts of chromium and manganese, which enhance their oxidation resistance and structural integrity during thermal cycling and pressure changes.
