High Carbon Steel Supplier
Consolidated Metal Service, Inc. supplies, slits, and processes high-carbon steel coil and sheet in both annealed and tempered conditions to your exact tolerances and specifications.
High Carbon Steel Products
We carry and process high-carbon steel in both annealed and tempered forms, available as coil, slit coil, and strip. Annealed high-carbon steel is softened through controlled heat treatment to improve machinability, formability, and ductility — ideal for applications that require further forming or stamping. Tempered high-carbon steel undergoes an additional hardening and tempering cycle to achieve precise hardness and spring-back characteristics, making it the material of choice for springs, blades, and high-stress components.
We stock common gauges and widths, and our 40-year vendor network means we can source specific grades, carbon contents, or specialty requirements when our on-hand inventory doesn’t cover your spec.
Don’t see the material you need?
Our vendor network spans decades of relationships with specialized mills and distributors, so if you’re looking for a specific carbon content, hardness level, or a temper that isn’t standard, we’ll find it. Contact our team and tell us what you’re working with.
High Carbon Steel Processing Services
We slit high carbon steel coil to custom widths with the precision your application demands. Our equipment handles widths as narrow as .250 inches.
We offer multiple edge-finishing options for high-carbon steel strip, smoothing the slitting burr to ensure safe handling and future compatibility.
Benefits of High Carbon Steel Coil & Sheet
- Exceptional hardness and strength: Higher carbon content enables heat treatment to hardness levels not achievable with low or medium carbon grades
- Spring-back and fatigue resistance: Tempered high-carbon steel maintains consistent mechanical properties under repeated stress loading, making it the standard for spring and blade applications
- Versatile heat treatment response: Annealed forms process easily through stamping, forming, and machining; tempered forms deliver the finished-part performance characteristics right out of the coil
- Wide application range: From precision springs and saw blades to agricultural tools, fasteners, and automotive components, high carbon steel serves demanding applications across many industries
- Predictable tolerances: Consistent mechanical properties from coil to coil support high-volume production runs that require repeatable results
- Cost-effective strength: Delivers high strength and hardness at a lower cost than alloy or tool steels, making it the practical choice for many performance-driven applications
- Available in multiple tempers and carbon grades: Flexibility to match the exact performance spec your application requires

Frequently Asked Questions
What's the difference between annealed and tempered high carbon steel — and how do I know which I need?
Annealed high-carbon steel has been heat-treated to soften the material, making it easier to form, stamp, or machine. Tempered high-carbon steel is first hardened, then drawn back to a specific hardness level to deliver the spring-back and strength characteristics needed in finished components. If your process involves forming the steel after delivery, annealed is typically the right call. If you need the material to perform at hardness in the finished part, as in a spring or blade, you likely need tempered. Not sure which fits your application? Call us, and we’ll help you sort it out.
Does CMS offer toll processing for high-carbon steel?
Yes. If you own the material and need it slit, edge conditioned, or processed to spec, we’ll run it through our equipment on your behalf. We handle both large production runs and smaller one-off toll jobs, and we work around your schedule, including time-sensitive situations. Learn more on our toll processing page.
What edge finishes are available for high-carbon steel strip?
Edge conditioning matters any time your finished part will be handled directly or fed through tight-clearance tooling. We remove the sharp slitting burr and finish the edge to one of three profiles: a #5 deburred edge for basic burr removal, a #4 modified round for a smoother, partially rounded edge, and a #1 full round for a fully rounded, smooth edge suited for applications where safety or precise fit is a priority. We can walk you through which finish makes the most sense for your product or process.
Can CMS slit high-carbon steel to the narrow widths used in spring manufacturing and four-slide operations?
Yes. Narrow slitting is one of our core specialties. We regularly process high-carbon steel to widths as narrow as 0.250 inches, which covers most spring manufacturing and four-slide/multi-slide applications. Our dedicated precision slitters are built for this kind of work, and our rejection rate of less than 0.5% reflects the consistency narrow-slit customers require.
What industries commonly use high-carbon steel coil and sheet?
High-carbon steel is a workhorse material in demanding applications. Industries we regularly supply include spring manufacturing, automotive, stamping, four-slide and multi-slide fabrication, fastener manufacturing, blade and tool production, agricultural equipment, and HVAC. If your application calls for a tough, hardenable steel at a practical price point, high carbon steel is likely in the mix.
What are CMS's turnaround times for high-carbon steel orders?
In-stock high carbon steel ships in 1–5 working days. When schedules are tight, we offer rush service and will rearrange production to accommodate urgent needs. Our company-owned truck fleet handles Ohio deliveries directly, and we work with trusted freight partners for domestic and international shipments.
How does CMS handle high carbon steel to protect material quality and surface condition?
High carbon steel requires careful handling to avoid surface damage, edge nicks, or stress that can affect downstream processing. Our indoor, climate-controlled facility protects material from moisture and temperature fluctuations that can affect the condition of the coil. We use full crane access throughout the facility to move material safely, and our team’s experience with this material means we know where the handling risks are and how to avoid them.
