Classification Of Spring Stainless Steel

Technicians will inquire about the composition of Hashimoto’s shrapnel and the necessary qualities throughout every trade show and client visit. Hashimoto Precision compiled some data for your convenience based on these commonly asked questions:

As a corporation, we mostly employ spring stainless steel stamping parts for sheet springs in various machinery and vehicles.

Following Are Examples Of Applicable Specification Standards:

Springs made from JIS H 3130 white copper, phosphor bronze, and beryllium copper

Narrow stainless steel strip, cold-rolled, ISO standard ISO9447: 1990

Once you understand the product’s intended use for the consumer, you may choose the best material to manufacture it from. Verifying the material makeup is the initial step. The original manufacturer has minimum order quantity (MOQ) restrictions for certain supplies. You’ll have to negotiate with smaller material dealers if you’re testing with a tiny quantity. Some material suppliers are dishonest in claiming to offer imported goods on the certificate they issue but sell inferior materials. For this reason, it’s crucial to thoroughly vet potential vendors by tracking out the origins of their raw materials.

Currently, Hashimoto has to be able to track its receiving resources back to the mine before it will use them or choose a supplier. The supplier must provide the original material certificate, traceability investigation, multiple ingredients, origin, no dangerous compounds, and compliance evidence certifications. Although it serves as little more than a functional component in the completed medical device or automotive, its importance cannot be discounted. However, for the FMEA management connection, the material can only be tracked extensively so that the features can be better assured.

The materials above are cold rolled and calendared. Only the SUS420J2 annealing again after cold rolling and calendering, and SUS631 will undergo solid-soluble heat treatment (1000~1100°C quench). It is via these that the product’s material properties and stamping function are guaranteed.
