Hariom Steel

A stainless steel stud is a type of fastener that is threaded on both ends or throughout its entire length. Known for its exceptional strength and corrosion resistance, stainless steel studs are used in a variety of applications, particularly where durability and longevity are essential. They're common in the construction, automotive, and machinery industries, often serving as anchor bolts or components in flanged connections.

ASTM A193 Grade B8M Stud Bolts are offered with pair of A194 Grade 8M Nuts in finished or heavy hex profile. Hariom steel is a manufacturer and supplier of full threaded, double end threaded or tap end threaded stud bolts in both metric and imperial sizes with full compliance to ASTM A193 Grade B8M specification. B8M stud bolts are produced from heat-treated 316/316L bar stock as per desired class 1 or class 2 properties. These stud bolts carry coarse, fine or extra fine threads and are manufactured to B18.2.1, B16.5, B18.31.2, B18.31.1M, DIN 976, BS 4882, UNI 6610 and many other dimensional standards.

ASTM A193 Grade B7 specification covers requirements for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications. It is a standard specification defining typical chemical composition, mechanical properties, hardness requirement, preferential heat treatment, product marking, certification and other requirements, suitable for bolting used in pressure vessel service, valves, flanges and fittings. ASTM A193 defines both SI (Metric) and inch-pound units.

Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC. Hariom Steel uses Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts. A193 Grade B7 is the most commonly used Bolt specification coupled with A194 Grade 2H Nuts for Bolting Carbon Steel pipeline. A193 B7 bolting is available in metric sizes from M6 to M180 and imperial sizes from 1/4 to 7 inches, in diameter.
