1. What is the material of DF2?
1. DF-2 is a low-alloy tool steel, which can be divided into two categories: refrigeration mold and hot pressing die according to its main application. Refrigeration molds are mainly used for cold mold die casting and cold molding, such as manufacturing electronic product shells, etc.;Hot pressing molds are mainly used for die casting and forging, such as manufacturing auto parts and construction machinery.
2. Chemical composition of DF-2 material (DF2 tool steel) DF-2 has high hardness, wear resistance and impact resistance, and the main components are carbon, cobalt, tungsten, chromium and other elements. DF-2 use: Mainly used to manufacture high-speed cutting tools, stamping dies, planer knives, turning tools, etc., suitable for high-speed machining, high precision and high wear resistance requirements.
3. DF2 steel is a typical alloy tool steel, and its cold work mechanical properties are very good. DF2 steel has high wear resistance, micro-deformation cold work die steel, air-hardened tool steel, carbon content up to 95%, heat treatment hardness up to 6HRC. DF2 sections can be used to make molds with small cross-sections, complex shapes, and various gages.
4. DF2 is manganese-chromium-tungsten alloy steel, which is a high-quality cold work tool steel. The chemical composition of DF2 steel includes carbon, chromium, molybdenum, manganese, nickel, tungsten, vanadium, silicon and aluminum. Among them, the content of carbon is 95%, chromium content is 6%, molybdenum content is 2%, manganese content is 6%, and nickel content is 1%.
5. What material is QDF2 equivalent to in China?Answer Hello, DF2 is commonly known as oil steel, which is similar to the domestic CR12.
So the above content is some information about what DF2 is and what it is, I hope this article can help netizens get some of the content they want to know.
2. What is DF-5(2) material?
1. DF-5A bimetallic inlaid self-lubricating bearings are made of bimetal as the base material, and the solid lubricant with special formula is embedded on the substrate, and it is processed. It has the advantages of copper-based inlay material, because the matrix is made of bimetallic, it saves a lot of non-ferrous metal resources and reduces the user's use.
2. DF2 steel is ?This (hatchi) high-quality special steel, micro-deformation oil steel, excellent wear resistance. Quenching?After having a very?The hardness of the back?After having a better rulerStability Typical chemical composition (mass fraction) of this steel is as follows: C95%, Cr60%, Mn10%, V10%, W 60%.
