American galvanized SA193-B7 full thread stud

    There are thousands of types of screws, including ASME and Asmi standard high-strength bolts, studs, nuts, and non-standard special fasteners that are resistant to high pressure, high temperature, and corrosion.

     This type of product is mainly used in industries such as pressure vessels, high and medium pressure pump valves, radiators, petroleum drilling and production equipment, chemical plants, pipeline containers, offshore platforms, smelting equipment, etc.

     Product materials such as SA193 B7, B7M, B8, B8M CL1, CL2, B16, L7; SA194 2H, 7,8M, A307, A320, A325, etc. These special materials of products can maintain good mechanical properties from -196 ° C to 575 ° C through strict heat treatment or solid solution.

     The product manufacturing process, testing, and labeling also have strict regulations. Products such as SA193 B7 belong to the chromium molybdenum alloy steel material, which is higher than the highest grade 35CRMOA Screw material produced in China, grade 12.9. However, it undergoes high-temperature quenching at 860 degrees and high-temperature tempering at 640 degrees to reduce its hardness and maintain its performance level at 10.9. This greatly improves the toughness of the product, making it more flexible in the working environment and greatly increasing safety risks. In the labeling, it is mandatory to use the manufacturer's label AM and material label B7 to ensure good product traceability.American Galvanized Full Thread Stud,SA193-B7 Full Thread Stud,Galvanized SA193-B7 Full Thread Stud,American galvanized SA193-B7 full thread stud
