Product Description

Thousands of screws, ASME, resistant to high pressure, high and low temperature, corrosion, stainless steel bolts, studs, nuts, and non-standard special fasteners.

This product is mainly used in industries such as pressure vessels, high and medium pressure pump valves, radiators, petroleum diamond equipment, chemical equipment, pipeline containers, offshore platforms, smelting equipment, etc.Special Full Thread Bolt,Special B7 Full Thread Bolt,Special ASME Full Thread Bolt

SA193B7 and other product materials, B7M, B8, B8MCL1, L7, CL2, B16, etc,; Products made of special materials such as SA1942H, 7, 8M, A307, A320, A325, etc., undergo strict heat treatment or solid solution, and can maintain good mechanical properties at high temperatures ranging from -196 °C to 575 °C.

There are also strict regulations for the manufacturing process, inspection, and labeling of products. For example, SA193B7 product belongs to chromium molybdenum alloy steel, which is higher than the highest grade of 12.9 screws 35CRMOA material produced in China. However, through 860°C high-temperature quenching and 640°C high-temperature tempering, the hardness is reduced and the performance level of 10.9 is maintained. This greatly improves the toughness of the product, causing it to bend in the working environment, greatly increasing safety risks. In the marking, it is mandatory to mark the manufacturing trademark AM and material B7, which has good traceability for the product,Special ASME SA193-B7 full thread bolt.

Q&A

Question：What material is used for the special ASME SA193 B7 Full Threaded Bolts?

Answer：Special ASME SA193 B7 full threaded bolts are made of high-strength alloy steel, mainly manganese, chromium, molybdenum and other elements, which have good tensile strength, compressive strength and high temperature resistance, and can adapt to the needs of high temperature, corrosive and extreme working conditions.
