A193 B7 Alloy Steel Stud Bolt
Yokelink 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. Boltport 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.
A193 B7 Alloy Steel Stud Bolt Characteristics
ASTM A193 B7 Alloy Steel Stud Bolt Chemical Properties
Chemical composition: B7 is a chromium-molybdenum low alloy steel, the main components of which include carbon (0.37%-0.49%), chromium (0.75%-1.20%), molybdenum (0.15%-0.25%), as well as manganese, silicon and other elements. For large-sized bars (over 90 mm), the carbon content is allowed to be up to 0.50%59.
Material basis: Usually made of AISI 4140 or similar alloy steel to ensure high strength and high temperature resistance
