从India供应商批发进口3/4" Stud Bolt — FOB条款

KPS Metal Components produces this 3/4-inch stud bolt to ASTM A193 Grade B7, a chromium-molybdenum alloy steel specification designed for high-temperature, high-pressure service. The fastener features threaded ends on both sides of an unthreaded shank, allowing nuts to be drawn up against flanges in piping and pressure vessel assemblies. The Grade B7 designation specifies quenched and tempered alloy steel with minimum tensile strength of 125 ksi and yield strength of 105 ksi at room temperature, properties that degrade predictably with increasing service temperature up to approximately 538 degrees Celsius.

ASTM A193 Grade B7 is the most commonly specified material for stud bolts in the petrochemical and power generation sectors, with the chromium and molybdenum additions providing resistance to tempering at elevated temperatures that plain carbon steels cannot match. The 3/4-inch nominal diameter refers to the thread major diameter, with the unthreaded shank typically at or near major diameter for full-section strength. Heavy hex nuts to ASTM A194 Grade 2H are the standard pairing, and stud lengths are specified as overall length or first-to-first thread length depending on buyer preference and flange thickness stack-up. The bolts are normally supplied with a plain oiled or black oxide finish for corrosion protection during storage, though hot-dip galvanizing or PTFE coating can be applied for specific environments.

These stud bolts are essential maintenance and construction items for oil refineries, chemical plants, power stations, and offshore platforms. The double-ended design permits easier replacement of corroded or damaged studs without removing the flange pair. KPS Metal Components, based in Chennai, Tamil Nadu, offers these for international trade in bulk packaging. Buyers should confirm thread pitch (UNC 8TPI is standard for 3/4-inch coarse series, but 12UNF or 16UN fine series may be required), stud length, and whether chamfered or rounded ends are provided. Thread class 2A/2B is standard for commercial bolting, though 3A/3B may be specified for nuclear or critical service.

KPS Metal Components is located in Chennai, Tamil Nadu, India, with the specific address listed as Chennai 600048.
