The B7 stud bolt series from Yongding Industry Co., Ltd is manufactured to ASTM A193 Grade B7 and ASTM A194 2H standards, using chromium molybdenum steel for high-strength applications. These bolts are engineered for environments with extreme pressure and temperature, such as oil and gas extraction, refineries, and heavy machinery. The series includes a range of diameters and lengths to accommodate diverse industrial needs.
Chrome molybdenum steel in B7 grade offers exceptional tensile strength, typically exceeding 125 ksi, and maintains integrity at elevated temperatures. The bolts are designed to resist corrosion and galling, with surface treatments available to enhance durability. Standard industry practice for B7 studs includes uniform heat treatment to achieve consistent mechanical properties, with typical hardness values falling within 28-32 Rockwell C.
Buyers in construction, petrochemical, and power generation sectors rely on these bolts for critical joints in pipelines, valves, and structural assemblies. Customization options include thread types, coatings, and lengths to fit specific engineering drawings. Confirm compliance with project-specific standards, such as ASME BPVC for boiler and pressure vessel applications, and request dimensional inspection reports for precision-critical installations.

Prior to ordering, confirm the exact specifications, such as diameter, length, thread pitch, and surface treatment, to ensure the bolts match your assembly requirements. Request a material test certificate (MTC) to verify compliance with ASTM A193 Grade B7, including tensile strength, yield strength, and hardness. For critical applications, ask for additional certifications like EN 10204 3.1 or PMI testing to validate material composition.
Discuss lead times for both standard and custom orders, as non-standard dimensions or finishes may require additional production time. Clarify Incoterms, such as FOB Ningbo or CIF destination, to determine shipping costs and responsibilities. Payment terms, such as TT or LC, should be negotiated upfront to align with your procurement policies and mitigate financial risk.
Upon delivery, inspect the bolts for dimensional accuracy, thread integrity, and surface finish quality. For high-stakes projects, consider third-party inspection services to verify compliance with project specifications. Ensure all documentation, including packing lists, certificates of conformity, and test reports, is complete and accurately reflects the ordered quantities and specifications.
