Product Overview

MicroTech supplies premium Alloy Steel Flanges designed for high-temperature and high-pressure applications. These flanges are manufactured from low-alloy steels with enhanced mechanical properties and temperature resistance.

Alloy Steel Flanges are ideal for power generation, petrochemical refineries, and high-temperature piping systems where standard carbon steel cannot meet performance requirements.

Available in grades P5, P9, P11, P22, and P91, our alloy steel flanges conform to ASME B16.5 and other international standards.
