S.R. Forgings manufactures and supplies ASTM A193 Grade B7 and Grade B7M stud bolts, threaded rods and industrial fastening solutions for demanding applications across oil & gas, petrochemical, power generation, refineries, heavy engineering and process industries. The company has been manufacturing in Ludhiana since 2009.
Our ASTM A193 Grade B7 and B7M stud bolts are manufactured from chromium-molybdenum alloy steel and heat treated to meet international standards for high-pressure and high-temperature service. Every batch undergoes quality inspection for dimensional accuracy, mechanical performance and traceability. B7M fasteners are specified for critical flange connections where controlled hardness is essential.
