Product Description
For countless industrial and commercial products, the backbone is steel. Stamped steel parts offer an unmatched combination of mechanical strength, material availability, and cost-effectiveness. From heavy equipment brackets to precision electronic frames, stamped steel components dominate applications where reliability under load is essential.
Nuote Metals has produced high-quality stamped steel parts for over a decade. Our presses handle low-carbon, high-carbon, and alloy steels in thicknesses from 0.3mm to 6.0mm. We combine material science with efficient stamping processes to deliver components that meet rigorous performance standards without unnecessary cost.
What Are Stamped Steel Parts?
Stamped steel parts are metal components formed by feeding steel coil or sheet into a stamping press equipped with custom dies. The press performs operations such as blanking, piercing, bending, drawing, or embossing to create the final shape.
The term “stamped steel parts” typically refers to components made from carbon steel or low-alloy steel—distinct from stainless steel, aluminum, or brass. Common steel grades include:
Low carbon steel (SPCC, SPCD, Q195, 1008) – Excellent formability, economical
Medium carbon steel (S45C, 1045) – Higher strength, wear resistance
High carbon steel (SK5, 1080) – Spring temper, hardness
Alloy steel (SPRING STEEL, 51CrV4) – High fatigue resistance for dynamic loads
Nuote Metals selects the optimal steel grade for each application, balancing formability, strength, cost, and surface finish requirements.
Why Choose Steel for Stamped Components?
Steel remains the most widely stamped material for good reason. Nuote Metals highlights these advantages of stamped steel parts:
High strength-to-cost ratio – Steel offers greater strength than aluminum or brass at a lower material cost
Magnetic properties – Essential for sensors, relays, and electromagnetic assemblies
Weldability – Steel parts readily accept spot, projection, or laser welding
Plating compatibility – Zinc, nickel, tin, and other platings adhere well to steel
Availability – Steel coil is available globally with short lead times

Quality Assurance for Stamped Steel Parts – EEAT in Practice
Nuote Metals follows a comprehensive quality system tailored to the characteristics of stamped steel.
Experience with Steel Grades
Our metallurgists and tooling engineers have over 10 years of experience stamping carbon and alloy steels. We understand:
Springback behavior – Steel’s elastic recovery varies by carbon content; we compensate in die design
Burr formation – Softer low-carbon steel produces larger burrs than hard steel; we adjust clearances accordingly
Heat generation – Thick steel stamping generates significant heat; we use lubricants and press speed control
Expertise in Post-Stamping Treatment
Stamped steel parts require corrosion protection for most applications. Nuote Metals operates in-house zinc plating and partners with certified coaters for powder coating and e-coat. We provide:
Coating thickness measurement – X-ray fluorescence (XRF) for plating
Adhesion testing – Cross-hatch tape test per ASTM D3359
Salt spray testing – ASTM B117 for corrosion resistance validation

Frequently Asked Questions About Stamped Steel Parts
Below are the most common technical inquiries received by Nuote Metals regarding stamped steel parts.
Q1: What is the difference between low carbon and high carbon stamped steel parts? How do I choose?
A: The carbon content determines strength, hardness, and formability. Low carbon stamped steel parts (SPCC, 1008, 1010) contain less than 0.15% carbon. They are soft, ductile, and easy to stamp into complex shapes including deep draws and tight bends. However, they have relatively low strength (tensile 270–400 MPa) and cannot be heat-treated for higher hardness. High carbon stamped steel parts (SK5, 1080) contain 0.75–1.0% carbon. They are much stronger (tensile 800–1,100 MPa after hardening) and can be heat-treated to HRC 50–60. However, they are less formable (minimum bend radius 2xT or more) and require heavier presses. Nuote Metals recommends low carbon steel for brackets, enclosures, chassis, and drawn housings. Recommend high carbon steel for springs, clips, retainers, and wear-resistant parts. For applications needing strength between these extremes, medium carbon steel (1045) offers a balance.
Q2: How does Nuote Metals prevent rust on stamped steel parts before they are assembled or coated by the customer?
A: Steel rusts rapidly when exposed to humidity. Nuote Metals takes several measures to protect stamped steel parts during storage and transit. First, for parts that will be plated or coated by us, we process them within 24–48 hours of stamping to minimize oxidation. Second, for parts shipped in the “as-stamped” condition (uncoated), we apply a rust-preventive oil (light, removable with alkaline cleaner) and package them in moisture-barrier bags with desiccant. Third, we offer temporary phosphate coating (manganese or zinc phosphate) which provides 1–3 months of indoor rust protection and also improves paint adhesion for customers who will paint later. For long-term storage or international shipping, we recommend that customers specify a protective coating (zinc plating or e-coat) as part of the order. If you receive stamped steel parts that show light surface rust, it can usually be removed with a mild abrasive or acid pickle—but for critical applications, specify a corrosion-prevention plan with Nuote Metals at the quoting stage.
Q3: What is the maximum thickness of stamped steel parts that Nuote Metals can produce? Do thicker parts require special tooling?
A: Nuote Metals can stamp steel up to 8.0mm thickness for simple blanking operations, and up to 6.0mm for parts requiring bending or forming. However, thick stamped steel parts (above 4.0mm) require special considerations. First, the press tonnage increases significantly—a 6.0mm thick steel part may require 200–400 tons depending on blank size. Second, tool clearances must be increased (typically 10–15% per side) to prevent excessive burrs and tool breakage. Third, thick steel has minimal elastic recovery, so springback compensation is less critical but edge cracking becomes a concern for holes near edges. Nuote Metals has press capacity up to 400 tons and maintains tool steel stocks suitable for heavy-gauge stamping. For parts thicker than 6.0mm, we often recommend laser cutting or plasma cutting as an alternative to stamping, as tooling costs become prohibitive. Send your thick-gauge drawing to Nuote Metals for a feasibility and cost comparison.
Q4: Can you stamp stamped steel parts with threaded holes or hardware inserts? What secondary operations are available?
A: Yes, Nuote Metals offers several methods to add threads to stamped steel parts. The most common are tapping (cutting threads directly into punched holes) and thread forming (for thicker steel, displacing material to create threads without chips). We have in-house tapping machines for holes from M2 to M12. For applications requiring stronger threads or removable fasteners, we can install inserts (PEM-style self-clinching nuts or studs) directly in the stamping die using automated insertion equipment. Other secondary operations for stamped steel parts include spot welding (projection welding of nuts or brackets), riveting (joining two stamped components), and heat treating (for high carbon parts needing spring temper). Specify any secondary operations on your drawing, and Nuote Metals will incorporate them into the process flow—often within the same progressive die to reduce handling costs.
