The extreme wear resistance of the steel is because of the presence of elements like carbon, chromium, manganese and vanadium. A lot of manufacturers call D2 the king of wear resistance. Terrific Wear Resistance: This property makes D2 steel stand out in the market.But D2 is not tough for tasks like batoning. Yet, the toughness is not the least, as the steel can tolerate abuse and resist breaking and chipping. Toughness: Since D2 has a hardness rating above 61 HRC, this shows it has a high hardness level causing the toughness to be low because of an inversely proportional relationship.The rating can vary depending on the heat treatment provided to the steel. The hardness rating of the steel shows great wear resistance and superior edge retention capability. 0.02% of Sulphur: Improves machinability.Īccording to the Rockwell C scale, the hardness of D2 steel ranges between 55 and 62 HRC.0.45% of Manganese: Increases forge ability, hardenability and wear resistance.0.9% of Molybdenum: Increases hardness, hardenability, steel strength and toughness.1.1% of Vanadium: Brings improvement to steel strength, corrosion and wear resistance, and increases toughness.12% of Chromium: Adds tensile strength, increases edge retention and resistance to corrosion and wear.1.5% of Carbon: Increases the hardness of the steel and improves the resistance of the steel towards wear and corrosion.For these steel properties, manufacturers get to make deformation tools and cutting tools using D2. The chemical composition of D3 consists of 2.2% carbon, which is then decreased in D2 and manufacturers added elements like molybdenum and vanadium to increase the hardenability and toughness of the steel. You can shape the tool steel after cooling and also use oil and air quenching on the steel while maintaining the hardness level of the steel.ĭ2 was created as an alternative to D3 steel. The unique chemical composition of D2 allows it to belong to the cold work category. The steel has a polish-like finish on its surface giving the stainless steel look. For pure stainless steel, the percentage of chromium has to be above 13%. The chromium percentage is between 11.5 to 12 which makes D2 a semi-stainless steel. Along with carbon, steel consists of a high percentage of chromium, molybdenum and vanadium. But you will see D2 steel performing exceptionally in terms of performance, it is affordable and better than a lot of well-known premium knife steels.ĭ2 is air-hardening steel with the highest percentage of carbon in its chemical composition compared to other tool steels in the market. You will witness a lot of high-quality steel knives claiming durability but failing to last long and give desired performance.
