It is common belief that a simple test for stainless steel is to check with a magnet. If it attracts, the product is not stainless steel. However, this assumption is incorrect. All cold worked Stainless Steel Fasteners get magnetised. The extent of magnetism induced varies for different grades and is explained in ISO-3506

Circlips are used to prevent lateral movement. They are used as retaining rings on bearing assemblies and are manufactured using semi-flexible metal ring. These products are in a shape of a circle with a clip and are open from one end.

The most common form of axially fitted circlips for shafts with grooves.

Constructed as curved beams of uniform strength, the radial width is reduced towards the free ends so that a constantly round shape is maintained throughout continuous use. This form of circlip often used in assemblies subjected to strong centrifugal forces, is also secure against high rotational speeds. Lugs with holes are provided for rapid fitting or removal with circlip pliers.

Type B type internal circlips are used to prevent lateral movement of assembly components in a bore. These internal circlips are manufactured using high-grade spring steel or Stainless Steel. We offer these products in a huge variety of sizes, dimension and thicknesses to meet specific needs of our clients. Our complete range is strictly tested on the basis of different parameters.

 

These products are suitable for most normal engineering applications as these simply act as a rigid shoulder within a bore.

Material: Stainless Steel – 1.4122 and 1.4543-Aero

Stainless Steel 1.4543 Aerospace Grade is used widely in various aerospace applications.

Stainless steels divide into three groups of steel - austenitic, ferritic and martensitic. Austenitic steel is by far the commonest and offers the greatest scope for use. The steel groups and strength classes are designated by a four-digit sequence of letters and numbers as shown in the following example. DIN EN ISO 3506 governs screws and nuts made from stainless steel.
Example:A2 - 80A = austenitic steel2 = type of alloy within group A80 = tensile strength of at least 800 N/mm2, cold work hardened
