2. The 5 Undeniable Benefits of Carbon Steel - benefits and limitations of carbon steel
2.1
- Material cost:
0.80/lb (vs. 8.00 for stainless) - Machining cost:
30% lower than alloy steels Industry Impact : Accounts for 85% of structural steel projects (AISC data)
2.2
(Comparison: Yield Strength at Same Thickness)
| Material | Yield Strength (MPa) | Weight Index |
|---|---|---|
| 250 | 1.00 | |
| Aluminum 6061-T6 | 275 | 0.35 |
| Stainless 304 | 215 | 1.02 |
| Titanium Gr5 | 880 | 0.60 |
Note: Medium carbon steel achieves 600+ MPa after heat treatment
2.3
Forming : Cold rolling reduces thickness by 80% without cracking Welding : Low-carbon grades enable 95% weld efficiency Machining : Cutting speeds 2x faster than nickel alloys
2.4
95% Recycled Content : Highest among industrial metals - Closed-loop systems recover
98.7% of fabrication scrap
3. The 3 Critical Limitations & Solutions - benefits and limitations of carbon steel
3.1
Oxidation Rates in Marine Environments
| Material | Mass Loss (g/m²/year) | Relative Corrosion Rate |
|---|---|---|
| Bare Carbon Steel | 500-800 | 1.00 |
| Galvanized Steel | 15-40 | 0.05 |
| Stainless 316 | 0.5-2.5 | 0.003 |
Protective Coatings : Epoxy/Zinc-rich systems (5-15 mil thickness) Alloy Blending : Huaxiao-Alloy’s proprietary COR-TEN® alternative Design Adjustments : 10% wall thickness compensation for expected corrosion
3.2
Low-Temperature Risk : Impact strength drops 60% at -50°C High-Carbon Limit : Hardness over HRC 55 increases fracture risk
| Application | Recommended Grade | Charpy V-Notch (J) at -40°C |
|---|---|---|
| Arctic Pipelines | API 5L X80 | 40-60 |
| Tooling | SAE 1070 | Not Recommended |
| Cryogenic Tanks | ASTM A537 CL1 | 25+ |
3.3
Density : 7.85 g/cm³ (vs. 2.7 for aluminum) Transport Cost Impact : Adds 15-25% logistics expense
Hybrid Structures : Carbon steel frames with aluminum panels Precision Engineering : Huaxiao-Alloy’s thin-wall tubing solutions
