Frequently Asked Questions

Can CustomSprings manufacture springs in 301 Stainless Steel?

The material is included in the CustomSprings material library for RFQ screening. Final feasibility depends on wire or strip form, size, heat treatment, load, environment and quantity.

Does the material page guarantee certified properties?

No. The material values are engineering reference data. Certified properties or test reports must be specified during production quotation.

What if there are no matching reference rows?

Use the RFQ form with your drawing and application data. The material can still be reviewed as a made-to-drawing option.
