Piyush Steel is one of the renowned suppliers, manufacturers, and distributors of ASTM A193 grade B7 fasteners. ASTM A193 Grade B7 is a chromium-molybdenum alloy steel commonly used to manufacture high-strength mechanical fasteners such as ASTM A193 Grade B7 bolts, studs, and threaded rods. This grade of fasteners has been designed to meet a specific set of mechanical and physical properties that make it suitable for demanding applications in various industries. The composition of the ASTM A193 Grade B7 fastener consists of a range of elements, including chromium, molybdenum, and vanadium.

ASTM A193 Grade B7 fasteners are made from alloy steel and heat-treated to achieve the desired level of strength and durability. ASTM A193 B7 fasteners are designed to withstand high levels of tensile stress, making them ideal for various industrial applications. They have a minimum yield strength of 105 ksi, which means they can handle a working load of up to 105,000 pounds per square inch without breaking. Also, Grade B7 fasteners have excellent corrosion resistance properties. They can resist rust and other types of corrosion that can weaken the integrity of a joint. This feature makes them ideal for harsh environments such as marine applications, chemical processing plants, and offshore rigs. Another grade of ASTM A193 Fasteners is available, i.e. ASTM A193 Grade B16 Fasteners .
