ASTM A193 Grade B16 Bolts are made up of carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, vanadium and aluminum in the composition. Viha Steel & Forging is a leading manufacturer and supplier of the b16 bolt material and other fasteners. The material has high hardness with 321 BHN. The minimum yield strength of the material is 100ksi to 125ksi depending on the production methods and sizes. The ASTM A193 B16 Studs come in sizes ranging from ¾ inches to 8 inches.
There are hot rolled, heat treated and machined types with cold finished and heat treated types. The astm a193 b16 equivalent grades and specification of the b16 bolts nuts is for high tensile, high temperature and special purpose applications. The chromium, molybdenum, vanadium alloy has up to 860MPa minimum tensile strength. The vanadium addition in the sa193 b16 Studs make them hold the strength even at elevated temperatures. The fasteners can withstand temperatures up to 450 degrees Celsius. The applications therefore are in the power generation industries.
Nuclear, thermal, hydropower and other types of power generation plants use the b16 bolts and other types. There are bolts, screws, threaded rods, stud bolts, washers and nuts. The different types are useful in different application requirements. The a193 gr b16 hex bolts are special with a unique head type that is used to hold components in a floating position. As a leading manufacturer and supplier of the different types, sizes and shapes of the B16 grade bolts. Please feel free to contact us for more information on the different types such as the b16 transmission bolts and others with their prices.
