China ASTM A193 Grade B16 Stud Bolts,A193 B16 Stud Bolts manufacturer
ASTM A193 Grade B16 is a bolting specification for high temperature service. It is a heat treated Chromium-Molybdenum-Vanadium steel. The specification calls for minimum strength and maximum hardness levels. It is considered to be most suitable for bolts used at temperatures below 840°F or 450° C.
The A193 Grade B16 Stud bolt is commonly used in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high-pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
A193 B16 stud bolts are a type of high temperature, high strength alloy steel fastener commonly used in oil and gas, petrochemical, and power generation industries. They are made from ASTM A193 Grade B16 steel, which is a chromium-molybdenum-vanadium alloy steel with a minimum tensile strength of 125 ksi and a minimum yield strength of 105 ksi.
A193 B16 stud bolts are typically used in high temperature and high pressure applications such as flanges, pressure vessels, and valves. They come in various sizes and lengths to accommodate different applications and are often used in conjunction with A194 heavy hex nuts to provide a secure and reliable fastening solution.
