What Is 65mn Steel?
A Chinese steel that has good wear resistance, hardness, and toughness, 65Mn is a readily available steel produced to provide edge-holding. This is because the addition of silicon to 1060 steel makes it approximately comparable. This high-carbon steel is primarily used to manufacture various small-section flat springs, round springs, clockwork, etc. Other applications of this metal include spring rings, valve springs, shock absorbers, clutch reeds, and brake springs.
65 MN steel composition
- 0.65% of Carbon: It increases hardness and wear resistance, but a high concentration of it reduces strength.
- 0.20% of Chromium: Strengthens the edges, improves corrosion resistance, and enhances wear resistance.
- 1% of Manganese: Enhances hardness and rigidity.
- 0.3% Silicon: Improves Strength.
- 0.04% of Phosphorus: Increases strength.
- 0.05% of Sulfur: Increases workability.
The 65 Mn steel we are looking at is made up of a combination of Carbon, Chromium, and Manganese, which is why spring alloys are made of it.
65 Mn Steel Properties
The 65 MN Steel can be classified based on its chemical composition and hardness (HRC) as follows:
65 MN Edge Retention: Its maximum hardness is 34HRC, making it hard, therefore providing good edge retention.
65 MN Corrosion Resistance: Corrosion resistance is not very good with only 0.2% chromium.
65 MN Wear Resistance: Wear resistance is good with this steel since it contains 0.65% carbon.
65 MN Sharpness: Sharpening steel harder than 65MN is more difficult as the rule goes. It is harder steel that would take more effort to sharpen.
65 MN Toughness: The toughness of the alloy is due to the combination of carbon, chromium, and manganese.
Is 65mn Steel Good For Knives?
The answer is Yes, It is made from Chinese spring steel, which is resistant to wear and tough. A comparison with 1065 would be appropriate. Manganese is present at a high level of 0.90-1.20 percent, and a medium amount of carbon is present at 0.62-0.70%.
The steel is tougher, resilient, and has better hot-working properties because of these properties, making it a good choice for sword blades. It also has a minute amount of silicon (0.17% to 0.37%).
If you’re looking to baton,EDC, or use in a harsh environment like a wet environment, 65 MN steel would give the best results, but it would not work as well for weld, because of its low corrosion resistance.
Therefore, if you’re hunting, fishing, or cooking, I don’t recommend 65Mn steel knives.
How Hard Is 65 Mn Steel? – 65mn Steel Hrc
It can be used for making knives, machetes, small-section flat springs, rounds springs, clockwork, etc. It is a low alloy carbon steel. Because it is carbon steel, it is hard, but its corrosion resistance level is lower. It has a hardening capacity between 28 and 34 HRC, making 65 Mn a hard steel.
65 MN Steel Equivalent
65Mn steel is considered to be equivalent to AISI SAE 1065, and some people also compare 65Mn with AISI/SAE 1075, 1095, 5160; JIS SK5 (SK85) and Chinese 8Cr13Mov, so the table below lists the difference of chemical composition for your reference.

There are a lot of common items manufactured with 65Mn carbon steel and 1095 spring steel. A decision on the material to use for manufacturing will be based on your manufacturing process and the specific properties of the finished product. Both 65Mn and 1095 have applications in the manufacture of knives, antennas, spring clamps, spring rings, shock absorbers, clock hands, and vehicle coil springs.

Final Word
This steel is made with a combination of special carbon and manganese, so it is hard and resistant to corrosion. If you have a big knife, you can be sure that you can use it in a wet condition, but big knives are just as effective as small ones. For its low corrosion resistance, I’d recommend this steel if you can maintain the knife after every use by keeping it dry and clean.
