Description of Material
ASTM A193 B16 is an alloy steel combining vanadium, chromium, molybdenum and is used throughout the Oil and Gas and Power Generation industries as a cost effective bolting solution and high-pressure, high temperature applications.
LoneStar Fasteners Europe offer ASTM A193 B16 to cover the basic requirements of ASTM A193 but can also offer with supplementary and additional requirements of the standard or industry specific requirements to demonstrate the integrity at elevated temperatures within a specific application.
