The material characteristics of the double ring road sub ring are mainly reflected in three aspects: high strength, corrosion resistance, and process optimization. Its core materials are mainly 304/316 stainless steel and SUS steel, which are treated with special processes to improve performance and meet the high requirements of the road fishing method for connectors. The following is a specific analysis:
1. Material type: 304/316 stainless steel and SUS steel are widely used
304 stainless steel
As the mainstream material of Luya double ring, 304 stainless steel has high strength and corrosion resistance, suitable for freshwater and mild seawater environments. For example, the "304 stainless steel double ring flat ring" recommended by Tiktok users adopts a beveled design, which is resistant to violent pulling without deformation, rust and corrosion, and polished smooth without burrs. The minimum tension is up to 15kg, and can be opened and closed repeatedly.
316 stainless steel
Compared to 304316 stainless steel with added molybdenum element, it has stronger corrosion resistance, especially suitable for seawater environment. For example, AIGEMA's double ring stainless steel reinforced compression three pin hook connector shows no signs of rust even after immersion in seawater. When paired with iron plate bait for settling action, it rotates smoothly and the bite signal is clear.
SUS steel
Some high-end models (such as OWNER Ouna [P-12] Sea Fishing Road Ya Double Ring Connection Ring) use SUS steel, and the side circular shape is flattened through flat punching process to increase overall strength, strong tensile strength and not easily deformed. Its dual ring design provides greater tensile strength, and the inner diameter uses a unique angled design, making it easier to replace parts.
2. Material characteristics: high strength, corrosion resistance, and process optimization
High strength and tensile strength
The double ring structure disperses tension and enhances connection strength through a double ring design. For example:
OWNER Euna [P-12] # 5 model has an inner diameter of 5.5mm and a double ring tension of 101LB (approximately 45.8kg), making it easy to handle explosive collisions from large fish such as GT giant scads and sea bass.
The Youdu Fishing Road Ya stainless steel flattened and reinforced flat ring is manufactured using high-precision CNC equipment, with a smooth and round body, super strong tensile force, and a minimum tensile force of 15kg, which is sturdy and durable.
Corrosion resistance and oxidation resistance
Stainless steel material is treated with electroplating or passivation to form a dense oxide film, effectively resisting the corrosion of chloride ions in seawater and freshwater. For example:
The AIGEMA dual ring connector shows no signs of rust even after long-term use in seawater environments, making it suitable for saltwater fishing scenarios.
The BKK double ring 8-shaped connecting ring is made of high hardness material, which has strong durability and has not rusted or deformed after multiple uses.
Process optimization: Flattening design and angled opening
Flattening process: By flattening, the gap between the fake bait and the connecting piece is reduced, making the fake bait enter the water more naturally and improving the smoothness of rotation. For example, when AIGEMA flattens the O-ring with three hooks, the stability is better, and the fake bait is thrown far and enters the water naturally.
Diagonal opening design: Some models (such as 304 stainless steel double ring flat rings) adopt a slanted opening design, which facilitates quick replacement of accessories and can be completed with one hand operation, improving fishing efficiency.
