Product Description
316 Introduction
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.316 also provide excellent fabricability and formability. It is also called Marine Grade Stainless Steel.
316 Eye Bolt Introduction
Eye Bolt is a specialized lifting and fastening hardware widely used for hoisting, rigging, anchoring and tension connection in industrial equipment and mechanical systems. Featuring a unique integral circular eye head and threaded shank structure, it provides a reliable fixed lifting point for wire ropes, chains and sling connections. Manufactured from high-strength carbon steel, alloy steel and stainless steel materials compliant with DIN, ISO and ASTM standards, eye bolts offer excellent tensile strength, structural stability and load-bearing capacity. With precise thread tolerance and smooth eye surface, they avoid sling wear and ensure safe and stable stress bearing. They are extensively applied in machinery manufacturing, shipbuilding, electric power, petroleum, chemical and construction industries for equipment hoisting, heavy load anchoring and movable tension fixing.

316 Eye Bolt Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality carbon steel, alloy steel and stainless steel rod materials that comply with DIN, ISO and ASTM standards. Strictly inspect chemical composition, mechanical properties, surface smoothness and internal metallographic structure to exclude cracks, inclusions and oxide defects. Qualified raw materials are precisely cut into standard fixed-length blanks according to eye bolt specifications for subsequent forming operations.
2.Heating & Hot Forging Forming:
Perform uniform heating treatment on qualified blanks to achieve optimal material ductility.Adopt precision die hot forging technology to complete integral forming of the circular eye ring, transitional shoulder and bolt rod body. The integral forging structure ensures continuous metal fiber flow, dense internal grain and uniform wall thickness, providing high tensile strength and stable load-bearing performance for lifting operation.
3.Trimming, Straightening & Heat Treatment:
3.Trimming, Straightening & Heat Treatment:
Remove forging flashes, excess edges and forming burrs. Implement precise straightening to ensure bolt rod verticality and eye ring flatness without deformation. Conduct professional heat treatment including quenching and tempering for high-strength grades and stress relief annealing for stainless steel types, effectively eliminating forging residual stress and improving overall toughness and fatigue resistance.
4.Precision Thread Machining:
4.Precision Thread Machining:
Adopt professional thread rolling and turning process to form standard full-size threads. Strictly control thread pitch, tooth profile and tolerance grade in accordance with industry standards. The precise thread processing ensures accurate meshing, stable locking performance and reliable load transmission during hoisting and fastening.
5.Surface Treatment & Quality Testing:
5.Surface Treatment & Quality Testing:
Carry out standardized surface treatments such as hot-dip galvanizing,electro-galvanizing, blackening and passivation to achieve anti-rust, anti-corrosion and wear-resistant effects. Complete full-range quality inspection including dimensional tolerance check, hardness testing, ultimate tensile load test, surface defect detection and nondestructive flaw detection to ensure full compliance with industrial safety standards.
6.Marking, Packaging & Warehousing:
Mark qualified eye bolts with material grade, load rating, standard code and production batch. Conduct sorting and counting, and adopt moisture-proof, collision-proof and standardized packaging.
