While it may not compete with higher-end steels in terms of edge retention, it still outperforms many regular high-carbon steels.
Sharpening 7cr17mov steel knives, on the other hand, is relatively easy. The steel’s combination of elements, such as carbon, molybdenum, and nitrogen, contribute to its strength and machinability. This means that the sharpening process is efficient and does not require specialized equipment or techniques.
In summary, 7cr17mov steel exhibits decent edge retention and straightforward sharpening characteristics. Its wear resistance and sharpness, resulting from the steel composition, make it suitable for general-purpose knives and an attractive option for those on a budget.
Corrosion Resistance and Toughness
7Cr17MoV is a Chinese stainless steel known for its corrosion resistance due to its high chromium content. Chromium, which makes up around 16.4% to 17.1% of the steel’s composition, actively prevents rust formation on the knife’s surface. The greater the chromium content, the better the resistance to corrosion and rust.
Another factor adding to the corrosion resistance of 7Cr17MoV steel is its level of carbon, which is about 0.7% of its composition. The carbon content is vital as it improves hardness and wear/corrosion resistance while maintaining its toughness.
Toughness is an essential aspect of knife steels, as it determines the ability of the steel to resist breaking or chipping during use. The 7Cr17MoV steel can be considered to be moderately tough, which makes it a suitable choice for survival knives and budget folding knives. Although it’s not as strong as some high-end grades, its properties provide a good balance between hardness, toughness, and corrosion resistance.
However, with increased hardness and wear resistance, there’s a likelihood of the steel becoming more brittle. Luckily, the levels of manganese (0.40% – 0.80%) and molybdenum (0.50% – 0.60%) in 7Cr17MoV steel help in reducing brittleness and improving the overall durability of the knife.
It’s worth highlighting that 7Cr17MoV steel doesn’t contain phosphorus, an element that can lead to brittleness in knife steels when present in high amounts. This lack of phosphorus makes the steel more reliable and suitable for everyday and survival use.
In summary, 7Cr17MoV steel offers a decent level of corrosion resistance and overall toughness for its price range. Its high chromium content and the absence of phosphorus are advantageous for users who need a knife that can withstand harsh environments and resist wear without breaking the bank.
