Product Description
316 Introduction
Alloy 316 is chrome-nickel austenitic alloy. It also contains molybdenum which increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at high temperatures. Alloy 316 also provide excellent fabricability and formability. It is also called Marine Grade Stainless Steel.
316 Fastener Hex Bolt Introduction
Hex Bolt is a widely‑used external threaded fastener with hexagonal head, also known as hexagon head bolt. It is designed for assembling and connecting mechanical parts, flanges, pipelines and industrial equipment. Material options include carbon steel, stainless steel, nickel‑alloy.Surface treatment is passivated for anti‑corrosion performance.Mainly applied in petrochemical, oil & gas, pipeline flange connection, machinery assembly, chemical industry and heavy‑duty equipment. Custom sizes and materials are acceptable.

316 Fastener Hex Bolt Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality carbon steel, alloy steel and stainless steel wire rods that comply with ISO, DIN and ASTM industrial standards. Strictly inspect chemical composition, tensile strength, surface smoothness and internal metallographic structure to exclude rust, cracks and inclusions. Qualified raw materials are precisely cut into fixed-length blanks according to bolt specifications for subsequent forming processing.
2.Heating & Cold Heading Forming:
2.Heating & Cold Heading Forming:
Perform surface pretreatment and precise temperature adjustment for blanks. Adopt professional multi-station cold heading technology to complete integral forming of hexagon head, rod body and transitional shoulder. The cold forming process ensures dense metal grain structure, high surface finish and uniform mechanical fiber flow,effectively improving the overall tensile strength and fatigue resistance of the bolt.
3.Trimming, Straightening & Heat Treatment:
3.Trimming, Straightening & Heat Treatment:
Remove forming burrs and excess margins, and implement precise straightening to ensure the verticality and straightness of the bolt rod. Conduct standardized heat treatment including quenching and tempering for high-strength bolts and stress relief treatment for stainless steel bolts. The process thoroughly eliminates forming residual stress and achieves stable hardness, toughness and comprehensive mechanical properties.
4.Precision Thread Rolling:
4.Precision Thread Rolling:
Adopt precision thread rolling process to form standard full-section threads. Strictly control thread pitch, tooth height and tolerance grade in accordance with standard requirements. The rolling forming mode ensures smooth thread surface, high tooth density and excellent meshing accuracy, realizing stable locking and fastening performance.
5.Surface Treatment & Quality Testing:
5.Surface Treatment & Quality Testing:
Carry out professional surface treatments such as galvanizing, blackening, passivation and anti-rust coating according to customer requirements. Implement full-range quality inspection including dimensional tolerance detection, hardness testing, tensile strength test, thread precision inspection and nondestructive flaw detection to ensure all indicators meet fastener industry standards.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Mark qualified hex bolts with grade specification, standard code and production batch.Conduct sorting, counting and standardized moisture-proof and anti-collision packaging. All finished products are stored in classified warehouses and delivered after strict final inspection.
