AISI A193 B7 B16 Hex Bars Manufacturer, Stockist and Exporter

AISI A193 B7 & B16 Hex Bars are high-strength alloy steel bars designed for heavy-duty industrial applications. These hex bars are widely used in the manufacturing of fasteners, bolts, and high-pressure flanges. They are renowned for their excellent tensile strength, toughness, and resistance to wear and fatigue. The bars are precision-engineered to meet strict dimensional tolerances, ensuring smooth performance in critical applications. Available in various sizes, these hex bars offer versatility in engineering and fabrication. Industries such as oil and gas, petrochemical, and power generation rely on them for reliable performance.

AISI A193 B7 Hex Bars are primarily alloy steel bars that are heat-treated to achieve high tensile and yield strength. They contain elements like chromium and molybdenum, which enhance hardness and resistance to corrosion. On the other hand, AISI A193 B16 Hex Bars are carbon-manganese steel bars, which are quenched and tempered for structural and mechanical applications. Both grades provide excellent machinability and are suitable for cold working. Their robust design ensures they can withstand high-pressure environments without deformation or failure. These properties make them ideal for manufacturing heavy-duty bolts, studs, and industrial fasteners.

The chemical composition of AISI A193 B7 & B16 Hex Bars ensures exceptional performance under stress. B7 typically contains 0.35–0.45% carbon, 0.60–0.90% manganese, and 0.40% chromium, while B16 contains slightly lower carbon and manganese levels. These chemical elements contribute to their mechanical strength, hardness, and durability. The precise metallurgical balance ensures minimal risk of cracking or failure during high-stress operations. Heat treatment processes, such as quenching and tempering, further enhance the bars' toughness and flexibility. These characteristics make them highly reliable for engineering applications requiring superior mechanical properties.
