Our C1074/C1075 hardened and tempered spring steel has a normal hardness range of RC 44/47 with typical tensile ranges of 208,000 to 230,000 PSI. If needed, we can offer other hardness and tensile ranges by placing special orders through many of our producing mills.
Looking for high-performance spring steel?
The standard finish for C1074/C1075 Tempered Spring Steel is scaleless. The color of this finish is normally dull grey but can also be provided as a scaleless blue, polished blue, or bright polished if required. Special mill orders may be required for non-standard finishes. This material is commonly used in the production of clips, coiled springs, washers, saw blades, trowels, and scrapers due to its strength and durability.
Scaleless Tempered Spring Steel Advantages
The big advantage of C1074/C1075 tempered spring steel is no heat treating is required after forming. Tempered Spring steel has limits on formability, but for many applications, this is a cost savings product compared to using annealed spring steel and post-heat treating.
In many cases, a round edge will be specified for this product. In certain applications, a round edge eliminates fractures occurring during forming and will extend the cycle life for mechanical spring products. We can provide this product with custom shaped “skived” edges, such as #5 de-burred, #4 round edge, #1 full round edge, and #1 square edge in ribbon our oscillate wound coils.

Frequently Asked Questions
Is 1075 steel better than 1095?
It depends on your application. 1095 steel is harder and more brittle, making it better for cutting tools. C1075 offers a more balanced mix of strength and flexibility, making it ideal for springs, clips, and mechanical parts.
What thicknesses and widths are available?
We offer a range of standard and custom thicknesses and widths. Please contact us for available stock sizes or to request custom slitting or shearing.
Is your C1075 spring steel suitable for forming or machining after purchase?
Yes, our tempered C1075 can be formed, though it has more limited formability than annealed steel. For applications requiring extensive forming or machining, we recommend discussing your needs with our team.
Can I order custom slit coils or sheared pieces of C1075 spring steel?
Absolutely. Tool King specializes in delivering custom-slit coils, sheared blanks, and specialty edges to meet your specifications.
Do you offer certifications or mill test reports with your spring steel shipments?
