Product Description

There are thousands of screws, including ASME and Asmi standard categories that are resistant to high pressure, high and low temperature, corrosion, stainless steel bolts, studs, nuts, and non-standard special fasteners.B7M Full Thread Stud,SA193-B7M Full Thread Stud,ASTM SA193-B7M Full Thread Stud

This type of 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.

Product materials such as SA193B7, B7M, B8, B8MCL1, L7, CL2, B16,; Through strict heat treatment or solid solution, products made of special materials such as SA1942H, 7,8M, A307, A320, A325, etc. 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 products belong to chromium molybdenum alloy steel, which is higher than the highest grade 35CRMOA Screw material produced in China, grade 12.9. However, through high-temperature quenching at 860 degrees and high-temperature tempering at 640 degrees, their hardness is reduced, keeping their performance level at 10.9. This greatly improves the toughness of the product, causing it to continuously 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 a good traceability effect on the product,High pressure resistant ASTM SA193-B7M full thread stud.

Q&A

Question：How do you ensure the quality of ASTM SA193-B7M fully Threaded Studs?

Answer：We produce and test in strict accordance with ASTM SA193-B7M standards and international quality management systems such as ISO 9001. Each batch of ASTM SA193-B7M fully threaded studs undergoes detailed material testing, mechanical property testing (including tensile strength, yield strength, etc.), and high pressure testing. We also carry out dimensional accuracy, thread accuracy and surface quality inspection to ensure that the performance indicators of the product meet the requirements. Each product is accompanied by a relevant test report and quality certificate, ensuring that every batch of studs delivered is of high quality.
