Product Name: A193 B8 Stainless Steel Full Thread Stud

Implementation standard : ASME B 18.31.2

Product Overview: A193 B8 stainless steel full thread studs are stainless steel studs for high temperature or high pressure and other special purposes. B8 stainless steel full thread bolts are also divided into two grades, A193 B8 class 1 and class 2, in terms of performance level. Class 1 is solution treated steel. Class 1A is solution treated in the finishing state to prevent corrosion; due to the requirements of physical properties, heat treatment is critical. Class 2 is solution treated machine strain hardened steel. When the diameter exceeds 20mm, strain hardened austenitic steel cannot show consistent characteristics across the entire cross section. A193 B8 studs are suitable for high temperature environments and can usually maintain their performance at temperatures of at least 800°C. They are widely used in industries such as petrochemicals, pharmaceuticals, food processing, and high-temperature oil refining. Its corrosion resistance and high temperature performance make it an ideal choice for these demanding environments.

①, U—— Thread chamfer distance:
The end chamfer is the dimension from the major diameter of the screw to less than or equal to the minor diameter. The distance from the chamfer end to the complete thread should be one to two pitch lengths each. The end of the stud should be perpendicular to the center of the stud, and both ends should be suitable for marking.
