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. While 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 spiral retainers and wave springs. The martensitic structure produced by oil quenching significantly enhances the tensile and yield strength of the material.
SAE1060-107
SAE1060-1075High-carbon hard-drawn spring steel is the standard material for clip retainer rings. The hard-drawn carbon steel has no grade because its strength is determined by the drawing process.
These carbon steels produced by these tempering processes are suitable for environments with existing protective measures, as they can corrode in the absence of lubrication or sealing. Additional corrosion protection can be achieved through special surface treatments. The retainers and springs are typically oil-immersed for surface treatment upon delivery to provide protection during transit and storage on shelves.
•Carbon steel is highly magnetic and can exhibit various colors, including blue, black, and gray.
Stainless steel
302Stainless steel
302Stainless steel is the standard stainless for spiral retainers. This material is widely used due to its combination of corrosion resistance and good physical properties.302The elasticity of stainless steel is derived from the cold working process. Although it is a non-magnetic type, it becomes so after cold working.302It will have a slight magnetic property. It cannot be hardened by heat treatment.

316Stainless Steel
316Stainless steel and302The physical properties and heat resistance of stainless steel are almost identical. Due to the presence of molybdenum, it boasts enhanced corrosion resistance, particularly against pitting corrosion.316Stainless steel is commonly used in food, chemical, and marine applications.

Super Alloy
InconelX-750
This nickel-chromium alloy is commonly used in high-temperature and corrosive environments. Two commonly used chromium-nickel iron alloys are described as follows. Under normal circumstances,InconelX-750Achieved spring condition through heat treatment. Alloys treated in this manner can withstand high371˚CTemperature.

Spring tempering and1The tempering number can be heat treated in an open-air or controlled atmosphere tempering furnace. Open-air heat treatment may result in oxidation, often leading to slight black residue. A controlled atmosphere environment eliminates oxidation issues, leaving no residue on the produced products.
•Retainer washers and springs made from this grade of chrome-nickel iron alloy are blue./Silver gray and non-magnetic.
Copper
25Beryllium Copper Alloy
Commonly used in its hard temper state, this alloy exhibits superior spring properties due to the combination of low modulus of elasticity and high ultimate tensile strength. The physical properties of the alloy are achieved through precipitation hardening. Compared to other copper alloys, beryllium copper alloys offer high strength and undergo minimal changes in physical properties with temperature increases.
•Beryllium copper alloys are non-magnetic. Their conductivity is approximately equal to that of phosphor bronze.2-4Multiple
AGrade Phosphor Bronze
Phosphor bronze offers excellent spring properties and conductivity, slightly inferior in performance to beryllium copper alloys. It is sold in spring temper to maximize spring characteristics.
•Phosphor bronze can only be hardened through cold working. This material also lacks magnetic properties.
Material Surface Treatment
Turn black
This surface treatment provides a matte black finish. Black oxide is primarily used for aesthetic purposes rather than for enhancing corrosion resistance.
Galvanized
Zinc is commonly applied to carbon steel to enhance product 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 comply withRoHSCoating thickness is determined by the service condition numberSC(No.) Decision allows the customer to proceed. Galvanizing does not necessarily cover the parts between each spring coil. This process can cause the retaining ring to become hydrogen embrittled.RaleighOffer stainless steel as an alternative choice for cadmium and zinc plating.
Oiled
This isRaleighAll products produced from carbon steel feature standard surface treatment. Oil imparts corrosion resistance during transportation and everyday storage. Oil immersion surface treatment should not be considered a durable surface treatment.
Passivation
Passivation is an optional cleaning process for stainless steel. It provides a bright 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 not dissolved, these foreign particles can cause rusting, discoloration, and even electrochemical corrosion.
In theory, the corrosion resistance of stainless steel is provided by a thin, invisible oxide film completely covering the retainer surface, which also prevents further oxidation. Removing contaminants can prevent the destruction of the oxide film, thereby achieving good corrosion resistance.
Phosphatized
The appearance is gray-black. Phosphate coating offers better corrosion resistance than black oxide, but is not as durable as cadmium plating or stainless steel. Phosphate coating is not applicable to stainless steel.
Steam Degreasing/Ultrasonic Cleaning
This is the standard cleaning and surface treatment for all stainless steel. The process uses chloride solvents to remove oil and other organic substances from the material's surface. This solvent effectively removes grease from the exposed surfaces of retainers or springs.
The solvent flows between each ring of the barrier ring through ultrasonic action.
Vibration Deburring/Manual burr removal
AlthoughRaleighAll circumferential surfaces and edges of the retaining ring are smooth, but due to shearing operations, sharp corners are always present at the gap ends. To remove the sharp corners and achieve a coordinated/The smooth surface finish allows for deburring via vibration or manual deburring of the retainer, to meet your requirements.
