Material Type
Selecting the appropriate material for application requiresRaleighWe have a good understanding of the common materials used in flat wire products. The correct material can prevent additional costs and malfunctions during operation. Carbon steel is a commonly used material. Although stainless steel is more expensive than carbon steel, it offers better corrosion resistance and a wider range of working temperatures.
Carbon Spring Steel
65Mn
SWRH 72A/72B
SAE1070-1090
SAE1070-1090High-carbon tempered spring steel is the standard material for helical retaining rings and wave springs. The martensitic structure produced by the oil tempering process significantly enhances the tensile and yield strength of the material.
SAE1060-107
SAE1060-1075High-carbon hard-drawn spring steel is the standard material for snap ring retainers. Hard-drawn carbon steel does not have a grade because its strength is determined by the drawing process.
These types of tempering processes produce carbon steel suitable for environments with existing protective measures, as this material will corrode in the absence of lubrication or sealing. Additional corrosion protection can be achieved through special surface treatments. The retaining rings and springs are typically supplied with oil immersion surface treatment for protection during transportation and shelf storage.
•Carbon steel has high magnetic properties and can display various colors, including blue, black, and gray.
Stainless Steel
302Stainless Steel
302Stainless steel is the standard material used for spiral retaining rings. This material is widely utilized due to its combination of corrosion resistance and excellent physical properties.302The elasticity of stainless steel originates from the cold working process. Although it falls under non-magnetic stainless steel, it becomes so after cold working.302It will have a slight magnetic property. It cannot be hardened by heat treatment.

316Stainless Steel
316Stainless steel and302Stainless steel has similar physical properties and heat resistance. Due to the presence of molybdenum, it boasts enhanced corrosion resistance, particularly against pitting corrosion.316Stainless steel is commonly used in food, chemical, and seawater applications.

A controlled atmosphere environment eliminates oxidation issues, leaving no residues on the products produced.

Copper

Typically used in its hard temper state, this alloy, with its combination of low modulus of elasticity and high ultimate tensile strength, exhibits excellent spring characteristics. The alloy's physical properties are achieved through precipitation hardening. Compared to other copper alloys, beryllium copper alloys have high strength and show minimal changes in physical properties with increasing temperature.

Material Surface Treatment
Turn black
This surface treatment provides a matte black finish. Black oxide is more commonly used for aesthetic purposes rather than for enhancing corrosion resistance.
Galvanized
Zinc is electroplated onto carbon steel to enhance the product's corrosion resistance. Compared to cadmium plating, zinc plating is often used as a more cost-effective and environmentally friendly alternative. Our standard zinc plating solution includes:TypeVAndTypeVIAll meet the standards.RoHSCoating thickness is determined by the service condition numberSC(Reference Number) determines, the customer can opt for this. Zinc coating does not necessarily cover the parts between each coil of the multi-spiral spring. This process can cause the retaining ring to undergo hydrogen embrittlement.RaleighOffer stainless steel as an alternative choice for cadmium and zinc plating.
Oiled
This isRaleighAll products produced with carbon steel feature standard surface treatment. Oil provides corrosion resistance during transportation and daily storage. Oil immersion surface treatment should not be considered a permanent surface treatment.
Passivation
Passivation is an optional cleaning operation for stainless steel. It provides a shiny surface and enhances corrosion resistance. Passivation can dissolve iron particles and other substances embedded in the surface of stainless steel during the production process. If these foreign particles are not dissolved, they can lead to rusting, discoloration, and even electrochemical corrosion.
In theory, stainless steel's corrosion resistance is provided by a thin, invisible oxide film that completely covers the retaining ring surface, which also prevents further oxidation. Removing contaminants can prevent the destruction of the oxide film, thus achieving good corrosion resistance.
Phosphatized
The appearance is gray-black. The corrosion resistance of the phosphate is better than that of black oxide, but not as good as cadmium plating or stainless steel. Phosphate cannot be applied to stainless steel.
Steam Degreasing/Ultrasonic Cleaning
This is the standard cleaning and surface treatment for all stainless steel. The process employs chloride-based solvents to remove oil and other organic substances from the material's surface. This solvent effectively eliminates grease from exposed surfaces of retainers or springs.
The solvent flows between the rings of the barrier ring through ultrasonic action.
Vibration Deburring/Manual burr removal
AlthoughRaleighAll circumferential surfaces and edges of the split ring are smooth, but due to the shearing operation, sharp corners are always present at the gap end. To remove the sharp corners and achieve a coordinated/The smooth surface finish allows for deburring by vibration or manual deburring of the retainer, to meet your requirements.
