Material Type

Selecting the appropriate materials 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 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 clip retainer rings. The hard-drawn carbon steel has no 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 these materials 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 oil-coated upon delivery to provide protection during transportation 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 material for spiral retainers. This material is widely used 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 nearly identical physical properties and heat resistance. Due to the presence of molybdenum, it boasts higher corrosion resistance, particularly against pitting corrosion.316Stainless steel is commonly used in food, chemical, and marine applications.

This nickel-chromium alloy is commonly used in high-temperature and corrosive environments. Two types of commonly used chromium-nickel-iron alloys are described as follows. Under normal circumstances,InconelX-750Through precipitation heat treatment to achieve spring condition. The alloy treated in this manner can withstand high371˚CTemperature.

Spring tempering and1Numbered tempering can be heat treated in open air or controlled atmosphere tempering furnaces. Open air heat treatment may cause oxidation, often resulting in slight black residues. A controlled atmosphere environment eliminates oxidation issues, leaving no residues on the produced products.

Copper

25Beryllium Copper Alloy

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

•Beryllium copper alloys are non-magnetic. Their conductivity is approximately equal to that of beryllium 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 offers a matte black finish. Black oxide is primarily used for aesthetic purposes rather than for enhancing corrosion resistance.

Galvanized

Zinc is galvanized onto carbon steel to enhance the product's corrosion resistance. Compared to cadmium plating, zinc galvanizing is often used as a more cost-effective and environmentally friendly alternative. Our standard galvanizing solution includes:TypeVAndTypeVIAll comply withRoHSCoating thickness is determined by the service condition number (SC(No.) The customer may decide on this. Galvanizing does not necessarily cover the parts between each spring coil. This process can cause the shims to become hydride embrittled.RaleighOffer stainless steel as an alternative choice for cadmium and zinc plating.

Oiled

This isRaleighAll products produced using carbon steel feature standard surface treatment. Oil imparts corrosion resistance during transportation and daily storage. Oil immersion surface treatment should not be considered as a durable 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 not dissolved, these foreign particles can lead to rusting, discoloration, and even electrochemical corrosion.

In theory, the corrosion resistance of stainless steel is provided by a thin, invisible oxide layer completely covering the retaining ring surface, which also prevents further oxidation. Removing contaminants can prevent the destruction of the oxide layer, thereby achieving good corrosion resistance.

Phosphatized

The appearance is gray-black. The corrosion resistance of phosphates is better than that of black oxides, but not as good as cadmium-plated or stainless steel. Phosphates cannot be applied 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 exposed surfaces of retainers or springs.

The solvent flows between each circle of the restrictor ring through ultrasonic means.

Vibratory Deburring/Manual burr removal

AlthoughRaleighAll circumferential surfaces and edges of the retaining 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 coordination/The smooth surface finish allows for deburring via vibration on the retainer or by hand to meet your specifications.
