Product Description

There are numerous types of screws, including high-strength bolts, studs, nuts adhering to ASME and ASMI standards, as well as non-standard special fasteners designed to withstand high pressure, elevated temperatures, and corrosion.

These products find primary applications in industries such as pressure vessels, high and medium pressure pump valves, radiators, petroleum drilling and production equipment, chemical plants, pipeline containers, offshore platforms, and smelting equipment, among others.

Product materials encompass SA193 B7, B7M, B8, B8M CL1, CL2, B16, L7; SA194 2H, 7, 8M, A307, A320, A325, etc. These specialized materials enable the products to maintain optimal mechanical properties within a temperature range of -196 °C to 575 °C through rigorous heat treatment or solid solution processes.

The manufacturing process, testing, and labeling of these products adhere to stringent regulations. For instance, products like SA193 B7 are made from chromium-molybdenum alloy steel, surpassing the highest grade 35CRMOA screw material produced in China, with a grade equivalent to 12.9. Nevertheless, it undergoes high-temperature quenching at 860 degrees and high-temperature tempering at 640 degrees to reduce hardness and maintain a performance level of 10.9. This significantly enhances the product's toughness, rendering it more adaptable to diverse working environments and substantially reducing safety risks. In terms of labeling, the use of the manufacturer's label "AM" and material label "B7" is mandatory to ensure robust product traceability.
