65mn Carbon Steel vs 1095 – How Do They Compare?

1095 has more carbon. 65Mn is a Chinese steel standard that is stronger than 1095. 65Mn is a better spring and has more maganese. 1095 has no chromium. 65Mn contains sulphur which increase machinability and makes it easier to sharpen.

 

Carbon is one of the steel components, which is contained in variable amounts reliant on the planned steel function being manufactured. These materials have a difference when it comes to manganese and carbon content. 65Mn steel refers to a GB standard Chinese steel. Its hardness, strength, hardenability, and elasticity are higher than the 65# steel.

65Mn is high manganese steel containing about 0.65 manganese which makes it effective for use as spring steel. It is high in carbon and hardness. The 65Mn carbon steel also has excellent toughness due to the strong mixture of Chromium, Carbon, and Manganese. This type of steel contains a mixture of Manganese, Chromium, and Carbon, making it a spring alloy. It also contains 0.04% phosphorus, 0.2% Chromium, and 0.3%Silicon to improve strength, wear resistance, and corrosion resistance. 0.05% of Sulphur helps to increase the machinability of the steel.

However, it has a superheat sensitivity which makes it easy to produce quench crack and temper fragility. When it comes to the ease of sharpness, the 65Mn is easier to sharpen than 1095. This can be attributed to its relatively low carbon content than 1095. Due to its greater machinability, it is easier to sharpen and also manufacture.

On the other hand, 1095 Steel is a basic type of carbon steel quite similar to the 65Mn, commonly used to construct various types of knives. However, the 1095 steel is manufactured in the US, unlike the 65Mn that is Chinese based. This type of steel is a favorite to most knife enthusiasts and makers and has earned a great reputation for grinding, forging, and offering an excellent sharp edge.

The 1095 steel has a 95% carbon content that hardens the steel and decreases the amount of wear that a blade experiences over time. This makes 1095 a bit higher in carbon content than the 65Mn. In addition to the 95% carbon, it contains 1.2% manganese, and silicon, copper, nickel, Molybdenum, and Aluminum. Finished products made of 1095 have better edge retention, which links to the material’s other properties. This is because of its higher carbon steel.

Although the high level of carbon hardens and reduces wear on the the 1095, this steel is not as tough as 65Mncarbon steel because of the lower level of manganese. The higher level of manganese in 65Mn serves to harden the steel more. However, the high manganese levels make the 65Mn to make more brittle blades than 1095.

Another difference between these two metals is that 1095 has no chromium in its mixture. This gives it very low corrosion resistance, meaning it requires great maintenance to avoid rust compared to 65Mn with a certain chromium percentage.

 

Common Applications

Both 65Mn carbon steel and 1095 spring steel are used for creating a lot of the same products. The decision on the type of material to use in manufacturing will be contingent on your manufacturing process and the specific properties you would want the final product to have. Both 65Mn and 1095 can be used to manufacture; knives, antennas, spring clamps, spring rings, shock absorbers, clock hands, and vehicle coil springs.

As you have read, the 65Mn and 1095 steel are very close in terms of corrosion resistance, edge retention, toughness and are both easy to sharpen. Both these steel metals are high carbon spring steel. However, 1095 is a bit higher in carbon, but the difference is not too much, depending on your use. If your application is critical, they are not ideal substitutes for each other.
