Product Name
Cold Rolled 1045 Carbon Steel Sheet 2MM thickness Sheet Metal(Standard & Custom Thicknesses)
Material Composition
1045 carbon steel is a medium-carbon steel renowned for its balanced combination of strength, hardness, and machinability. Key composition:
Carbon (0.42-0.50%): Provides moderate hardness and tensile strength.
Manganese (0.60-0.90%): Improves hardenability and wear resistance.
Silicon (0.15-0.35%): Enhances dimensional stability during processing.
International Standards
Compliant with:
ASTM A109 (Standard Specification for Cold-Rolled Carbon Steel Sheet)
EN 10130 (Cold-Rolled Low Carbon Steel Flat Products)
JIS G3141 (Cold-Rolled Carbon Steel Sheet and Strip)
Custom certifications (ISO 9001, IATF 16949) available upon request.

Core Features
1. Precision Dimensional Control
Tight Tolerances: Thickness tolerance within ±0.002" (0.05mm) and flatness deviation <0.010"/ft, ensuring seamless integration into automated manufacturing processes.
Uniform Surface Finish: Ra ≤ 1.6μm (63μin) surface roughness, reducing the need for post-processing in decorative or functional applications.
2. Mechanical Consistency
Annealed for Workability: Post-rolling annealing eliminates internal stresses, enhancing formability for complex stamping, deep drawing, or bending tasks.
Heat Treatable Potential: Can be quenched and tempered to achieve higher hardness (up to HRC 40) for components requiring increased wear resistance.
3. Versatile Application Ready
Weldability: Excellent fusion and resistance to cracking, suitable for arc, spot, and laser welding processes.
Machinability: Smooth chip formation during milling, turning, or drilling, reducing tool wear and improving production efficiency.
4. Cost-Effective Performance
Balanced Properties: Combines the strength of high-carbon steels with the formability of low-carbon grades, optimizing cost without compromising performance.
Minimal Waste: Consistent thickness and flatness reduce material scrap in large-scale manufacturing.

FAQ
Q: Can I bend or stamp 2mm cold-rolled 1045 steel without cracking?
A: Yes, but with care. 1045 is a medium-carbon steel and is less ductile than low-carbon 1008. For tight bends or deep drawing, you should order the material in the fully annealed condition to prevent edge cracking during stamping.
Q: How tight is the thickness tolerance for your cold-rolled sheets?
A: We hold a precision tolerance of ±0.05mm, much tighter than hot-rolled sheets. This ensures consistent feeding into automated stamping presses and minimizes waste. The flatness deviation is strictly controlled to less than 0.010 inches per foot.
Q: Can you guarantee a smooth surface finish for painting or plating?
A: Yes. Our cold-rolled 1045 sheets have a surface roughness of Ra ≤ 1.6μm. This smooth, scale-free finish reduces the need for grinding and provides excellent adhesion for subsequent painting or electroplating processes.
Q: What is the difference between your 1045 sheet and standard mild steel sheet?
A: 1045 has a much higher carbon content (0.42-0.50%) than mild steel. While mild steel is better for welding, 1045 can be quenched and tempered to achieve high hardness (up to HRC 40) after you stamp the part, offering better wear resistance.
Q: Do you supply small quantities for trial stamping?
A: Yes. We can cut trial sheets from our stock. You only pay the material and freight. If the trial is successful and you place a bulk order over $1000 within 90 days, the sample cost will be deducted from your invoice.
