Product Description
316L Introduce
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.Grade 316L, the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.
The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.
316L Stainless Steel Eye Bolt Introduce
Stainless steel eye bolt are universal fastening and lifting fittings widely used in lifting, marine and mechanical assembly industries, mainly available in 304 and 316 stainless steel grades. Each piece is integrally forged into shape with smooth, burr-free eye rings and precision standard threads, delivering stable and even load capacity while resisting cracking and deformation. Grade 304 offers outstanding cost performance for general indoor and freshwater environments. Containing molybdenum, grade 316 boasts superior resistance to acid, alkali and seawater corrosion, making it ideal for marine equipment, chemical machinery and outdoor exposed projects.All production processes comply with Chinese national standards and European & American lifting specifications. Every batch undergoes tensile load testing before delivery. We can supply complete material certificates, mechanical test reports and factory qualification documents to satisfy customs clearance and incoming quality inspection requirements worldwide. Metric and imperial thread sizes are customizable, along with adjustable eye ring diameters and bolt lengths for diverse applications including equipment lifting points, rope fastening and mold hoisting.The surface is polished and passivated to prevent rust and oxidation, maintaining a smooth finish even after long-term service. Our factory features large-scale production capacity to handle both small trial orders and mass shipments with stable lead times. Protective packaging prevents scratches and collisions during transit. Thanks to reliable anti-corrosion performance, standardized craftsmanship and full certification support, our stainless steel eye bolts are exported steadily to Europe, America, Southeast Asia and Australia, serving as durable preferred fasteners for industrial lifting and hardware matching.

316L Stainless Steel Eye Bolt Product Processing
Our stainless steel eye bolts adopt integral forging technology with standardized production to ensure high strength, zero porosity and stable load performance. The complete production process is as follows:
1. Raw material inspection: We use genuine 304/316 stainless steel bars. Each batch is spectroscopically tested to guarantee corrosion resistance and mechanical property.
2. Precision cutting: Raw materials are precisely cut with minimal tolerance to ensure uniform blank size for accurate forming and threading.
3. Hot forging forming: One-piece hot forging without welding points ensures solid structure, high load capacity and safety during lifting operation.
4. CNC thread processing: Precision CNC threading ensures standard thread shape, smooth assembly and no slipping, compatible with metric and imperial standards.
5. Polishing and passivation: Multi-time fine polishing removes burrs. Passivation treatment improves anti-rust, acid and seawater corrosion resistance.
6. Load performance test: Random tensile and load tests are conducted for every batch to meet industrial lifting safety standards.
7. Final inspection & packaging: Double inspection by machine and workers ensures stable quality. Professional packaging prevents damage during delivery.
