What is ISO 2338:1997 Parallel pins, of unhardened steel and austenitic stainless steel?
ISO 2338:1997 is a standard that specifies the dimensions, tolerances, and material requirements for parallel pins made of unhardened steel and austenitic stainless steel.
Parallel pins, also known as dowel pins, are cylindrical pins that are used to locate and align two or more components in a machine assembly. They are typically used to transmit shear forces, but not bending or torsional forces.
This standard specifies the following requirements for parallel pins made of unhardened steel and austenitic stainless steel:
Dimensions: The standard specifies the dimensions of the pins. Including the diameter, length, chamfer, and radius at the ends of the pin.
Tolerances: The standard specifies the tolerances for the diameter, length, and chamfer of the pin. As well as the perpendicularity of the ends of the pin with respect to the axis.
Material: The standard specifies the material requirements for the pins. Including the chemical composition and the minimum tensile strength.
Surface finish: The standard specifies the surface finish requirements for the pins. Including the maximum roughness and the absence of cracks, burrs, and other defects.
It is an important standard for ensuring the compatibility and interchangeability of parallel pins used in machine assemblies. So, By specifying the dimensions, tolerances, and material requirements for parallel pins made of unhardened steel and austenitic stainless steel, the standard helps to ensure the safe and effective operation of machines and equipment.
Requirements of ISO 2338:1997
Dimensions: The standard specifies the nominal diameter of the pins in the range of 1 mm to 20 mm, and the nominal length of the pins in the range of 2 mm to 200 mm. The standard also specifies the tolerances for the diameter, length, and chamfer of the pin.
Material: The standard specifies the material requirements for the pins. Including the chemical composition and the minimum tensile strength. For unhardened steel pins, the standard specifies that they must be made of carbon steel. While austenitic stainless steel pins must be made of steel that contains at least 16% chromium and 6% nickel.
Surface finish: The standard specifies the surface finish requirements for the pins. Including the maximum roughness and the absence of cracks, burrs, and other defects.
Marking: The standard requires that each pin be marked with the manufacturer’s identification, the nominal diameter and length, and the material.
ISO 2338 is an important standard for ensuring the compatibility and interchangeability of parallel pins used in machine assemblies. So, By specifying the dimensions, tolerances, material requirements, and surface finish for parallel pins made of unhardened steel and austenitic stainless steel.
Moreover, The standard helps to ensure the safe and effective operation of machines and equipment. The standard also helps manufacturers and users to select appropriate parallel pins for specific applications based on their material, diameter, and length.
Benefits of this ISO Standard
Interchangeability: The standard specifies the dimensions, tolerances, and material requirements for parallel pins. Ensuring that they are interchangeable between different manufacturers and applications. This can simplify the selection and sourcing of parallel pins and reduce the risk of errors or incompatibilities in machine assemblies.
Compatibility: The standard ensures that the parallel pins are compatible with other components in machine assemblies. Allowing for precise alignment and secure fixing of components. So, this can improve the performance, reliability, and safety of machines and equipment.
Quality: The standard specifies requirements for the material, surface finish, and marking of parallel pins. Ensuring that they are of high quality and suitable for their intended use. This can help to prevent failures and reduce the risk of accidents or damage to machinery.
Safety: The standard helps to ensure the safety of operators and maintenance personnel by specifying requirements for the surface finish and absence of defects in parallel pins. Thus, this can prevent injuries from sharp edges, burrs, or cracks in the pins.
At last, Global harmonization: The ISO 2338 is recognized and used worldwide. This helps to promote global harmonization of dimensions, tolerances, and material requirements for parallel pins. Facilitating trade and reducing technical barriers.
Overall, this standard for parallel pins made of unhardened steel and austenitic stainless steel provides important benefits for manufacturers, importers, regulators, and users of machine assemblies.
Moreover, The standard ensures that parallel pins are compatible, interchangeable, of high quality, and safe. Improving the performance, reliability, and safety of machines and equipment.
