1075
1075 is a lean, high-toughness carbon steel long favored for swords, machetes, and other hard-use blades where absorbing impact matters more than holding a razor edge for months. With less carbon and manganese than 1084, it demands a faster-quenching oil to reach full hardness, but rewards that extra care with exceptional resilience against chipping and bending.
1075 FAQ
Is 1075 good for swords and machetes?
Yes, it is one of the most commonly recommended steels for swords, machetes, and other large blades that need to survive hard impacts without chipping or snapping.
Is 1075 stainless?
No, it is a plain carbon steel with no chromium and needs regular oiling and drying to prevent rust.
Is 1075 hard to sharpen or grind?
No, it is easy to work with standard belts and stones. See the full grinding and sharpening guide.
How does 1075 compare to 1084?
1075 is tougher, making it the better choice for swords and choppers, while 1084 hardens more reliably in ordinary shop oil. See the full breakdown: 1075 vs 1084.
Also known as: 1075, AISI 1075, SAE 1075
Composition
| Carbon (C) | 0.70-0.80% |
| Manganese (Mn) | 0.40-0.70% |
Properties
| Property | Rating | Notes |
|---|---|---|
| Toughness | ★★★★★ | Among the toughest of the simple high-carbon steels, which is why it is the go-to choice for swords, machetes, and other blades that need to survive hard impacts without chipping or snapping. |
| Edge Retention | ★★☆☆☆ | Lower carbon content than 1084 or 1095 means fewer carbides and correspondingly modest wear resistance; expect to touch up the edge more often on demanding use. |
| Corrosion Resistance | ★☆☆☆☆ | No chromium and no meaningful corrosion resistance. Needs regular oiling and drying like any plain carbon steel. |
| Machinability / Grinding | ★★★★★ | Very easy to grind and forge, with a wide, forgiving heat-treat window that makes it a common recommendation for first-time bladesmiths. |
Heat Treatment
Austenitize at 1450-1480 F, holding 5-15 minutes. Because 1075 carries less manganese than 1084, it hardens best in a fast oil (such as Parks 50) rather than a slower conventional quench oil, reaching roughly 64-65 RC as-quenched. Temper in two 2-hour cycles: around 400-450 F for tough, hard-use blades like swords and machetes (57-61 RC), or as low as 300-350 F for applications favoring edge holding over shock resistance (63-65 RC), letting the blade cool to room temperature between cycles.
Best Uses
A favorite for swords, machetes, axes, and other hard-use tools where surviving impact matters more than long edge retention. If you are comparing it against similar simple carbon steels, browse the full Knife Steel Database, and see the Heat Treating Guide for the full stage-by-stage process.
