ASTM SA193-B7M Threaded Rod, High pressure resistant

ASTM SA193-B7M Threaded Rod, a high-pressure resistant product, is utilized in various industries such as pressure vessels, high and medium-pressure pump valves, radiators, petroleum diamond equipment, chemical equipment, pipeline containers, offshore platforms, smelting equipment, etc.

Materials such as SA193B7, B7M, B8, B8MCL1, L7, CL2, B16, along with special materials like SA1942H, 7,8M, A307, A320, A325, etc., undergo strict heat treatment or solid solution processes to maintain optimal mechanical properties across extreme temperatures ranging from -196°C to 575°C.

Manufacturing processes, inspection standards, and labeling requirements are strictly adhered to. For instance, SA193B7 products, crafted from chromium-molybdenum alloy steel, surpass the quality of the highest grade 35CRMOA Screw material produced in China (grade 12.9). By subjecting them to high-temperature quenching at 860 degrees and tempering at 640 degrees, their hardness is reduced, maintaining a performance level of 10.9. This enhances the product's toughness, allowing it to flex under working conditions, thereby enhancing safety. Markings must include the manufacturing trademark "AM" and material "B7" for effective traceability.

In summary, ASTM SA193-B7M Threaded Rod, a high-pressure resistant product, undergoes rigorous manufacturing and testing processes to ensure reliability and safety in demanding industrial environments.
