Suitable for low to medium strength structural parts, stamped parts, welded parts, cold heading parts, ordinary mechanical parts, low-cost metal parts, and carbon steel materials requiring good formability.
10# is a low-carbon, high-quality carbon structural steel with a low carbon content and good plasticity, toughness, weldability, and cold workability. It is suitable for manufacturing metal parts with low force requirements that require stamping, bending, welding, cold heading, drawing, or conventional machining. Compared to 45# steel, 10# steel has lower strength and hardness, but better formability and weldability; Compared to stainless steel, 10# steel is less expensive but has poorer corrosion resistance, usually requiring anti-rust treatments such as electroplating, blackening, painting, and phosphating.
By focusing on application scenarios, boundaries of advantages, and non-recommended scenarios, it helps sales, customer service, and quoting staff quickly determine whether the material meets current part requirements.
Low cost, good plasticity, good toughness, good weldability, good cold working performance, suitable for stamping and bending, suitable for general machining, can perform carburizing and surface treatment, and is suitable for low-cost batch metal parts.

The following parameters come from product information and material knowledge fields, used for design review, quotation communication, and preliminary judgment before material selection.
| Material positioning | Suitable for low to medium strength structural parts, stamped parts, welded parts, cold heading parts, ordinary mechanical parts, low-cost metal parts, and carbon steel materials requiring good formability. |
|---|---|
| Precision performance | 10# is suitable for CNC turning, milling, drilling, tapping, stamping, bending, and welding processes. CNC machining can achieve better dimensional accuracy; The accuracy of stamped bent parts is affected by plate thickness, die, springback, and material condition; The precision of welded parts is affected by thermal deformation and assembly processes. For precision assembly surfaces, hole positions, and thread positions, post-processing or separate tolerance marking is recommended. |
| Dimensional tolerances | Conventional dimensional tolerances for CNC machining 10# can be referenced as ± 0.02mm to ±0.10mm, while ordinary structural parts can be evaluated at ± 0.10mm to ±0.20mm; Stamped and cut parts can be referenced ±0.10mm-±0.30mm; The overall dimensional tolerance after bending welding can be referenced ± 0.30mm to ±1.00mm. These values represent the standard reference range and are not absolute guaranteed tolerances for all structures; actual confirmation must be made based on process, dimensions, structure, and post-processing. |
| Minimum Wall Thickness | The wall thickness of ordinary CNC-machined structures is recommended to be no less than 0.8mm-1.0mm; common plate thicknesses for stamped bent parts can be selected from 0.5mm, 0.8mm, 1.0mm, 1.5mm, up to 3.0mm or above. Low-strength thin-walled structures are prone to deformation; the load-bearing positions, threaded positions, and welding positions should be appropriately thickened. |
| Recommended wall thickness | Standard stamped parts and enclosures are recommended 0.8mm-2.0mm; ordinary structural brackets, connectors, and welded parts are recommended 1.5mm-3.0mm; positions bearing assembly forces, screw tightening, or light loads are recommended to be above 2.0mm, and rigidity should be improved through folded edges, ribs, flanges, or welded structures. |
| Minimum aperture | Stamping or laser cutting aperture is recommended to be no less than one time the plate thickness, and stable design suggests the hole diameter should not be less than 1.0mm-1.5mm. CNC drilling can achieve smaller diameters, but deep and small holes are more difficult to machine. It is recommended to reserve reasonable allowances for threaded holes, positioning holes, and assembly holes based on board thickness, processing method, and surface treatment thickness. |
| Assembly clearance | For ordinary metal assemblies, it is recommended to reserve 0.10mm-0.30mm on one side; for stamped bent parts, 0.20mm-0.50mm should be reserved on one side; for welded structural parts, the assembly allowance should be appropriately increased according to welding deformation. If further electroplating, powder spraying, painting, or blackening are needed, additional consideration of surface treatment thickness should be taken into account to avoid overly tight assembly. |
| Detailed performance | 10# steel is suitable for making holes, grooves, folded edges, flanges, welded structures, threads, steps, and ordinary mechanical details. CNC machining details are clear, and stamped parts are suitable for batch slot and contour forming. Small text, logos, and labels are recommended to be achieved through laser marking, stamping marking, etching, silkscreen printing, or inkjet coding. Excessive slot size and sharp edges require consideration of burrs, deformation, and processing costs. |
| Surface effect | The original surface of 10# steel is usually gray-black or silver-gray metallic surfaces, prone to oxide scale, scratches, or rust spots. After polishing, a relatively smooth metal surface is achieved; after blackening, a black rust-resistant appearance is obtained; after galvanizing, a silver-white or colored zinc appearance is achieved; after painting or powder spraying, multiple colors and better protection are achieved. If long-term appearance stability is sought, it is recommended to choose electroplating, spraying, or switching to stainless steel materials. |
Based on material characteristics and suitable product ranges, customer needs are broken down into easier application directions to determine.
Stamped parts, bent parts, welded structural parts, low-strength shaft parts, sleeves, gaskets, connecting pieces, stretched parts, cold heading parts, screw and nut billets, ordinary brackets, low-load structural parts, mechanical parts, ordinary automotive parts, hardware parts, and ordinary carbon steel parts used after surface treatment.
Suitable for low to medium strength structural parts, stamped parts, welded parts, cold heading parts, ordinary mechanical parts, low-cost metal parts, and carbon steel materials requiring good formability.
10# has low carbon content, the material is relatively soft, and it has good formability and weldability, making it suitable for stamping, drawing, bending, cold heading, and ordinary welded structures. Its inherent strength and hardness are not high, making it unsuitable for direct use as high-strength wear-resistant parts. Since it is ordinary carbon steel, it is prone to rust in exposed environments. In practice, the product usually requires blackening, electroplating, painting, phosphating, galvanizing, or other anti-rust treatments.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for 10#.
Post-processing of 10# affects appearance, dimensions, hole position, assembly clearance, and usage validation results, and should be explained in advance during quotation, DFM review, and sample confirmation stages.
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining, coating, and trial assembly allowances.
For common issues such as threads, snaps, strength, temperature resistance, and weather resistance, identify in advance whether the material needs to be replaced or if another processing method should be used.
When customer demand exceeds 10# material boundaries, it is necessary to combine strength, temperature resistance, toughness, long-term stability, and mass production goals to promptly recommend alternative materials or processing technologies.
If higher strength and hardness are required, 45# steel, 40Cr, or alloy steel can be chosen; If better corrosion resistance is required, 304 stainless steel, 316 stainless steel, or surface galvanized treatment can be chosen; If better cutting performance is required, easy-machining steel can be chosen; If you need a lighter weight, you can choose 6061 Aluminum Alloy or 5052; If a spring plate or highly elastic structure is needed, 65Mn, 301 stainless steel, or spring steel can be chosen.
If customers mainly care about low cost, good formability, weldability, and the use of ordinary structures,10# is a suitable choice. If customers require high strength, high hardness, wear resistance, corrosion resistance, or long-term outdoor use, it is not recommended to use exposed 10# steel directly. Instead, higher-strength steel, stainless steel, aluminum alloy, or reliable surface protection treatment for 10# steel should be selected.
