Specifications Cross Reference of Spring Wire Materials

When ordering a spring, the material specifications play an important role. Different countries have different material specification numbers and in the following list you can cross reference your material specification number with that of another country. Keep in mind that specifications to which we order our material are in blue type and the rest are just for reference.

Also, if you are looking to order springs check out the following article:
