1. If Q345 steel is used for cold drawing, what material should be used for the mold
1. If Q345 steel is used for cold drawing, the mold material should be cold work die steel, such as: cr1cr12mo1vcr12mov, etc. Cold drawing is a processing technology of materials, for metal materials, cold drawing refers to the drawing of materials at room temperature in order to achieve a certain shape and certain mechanical properties.
2. The distinction between Q235 and Q345 materials is welded: two steel plates of unknown material are butt and welded with ordinary welding rods, and if there is a crack on one side of the steel plate, it is proved to be Q345 material.
3. After cold drawing, it belongs to cold drawing. Round bars: In addition to the bright materials with precise dimensions, they are generally hot-rolled, and there are also forged materials (there are forging marks on the surface). Strip: both hot-rolled and cold-rolled, cold-rolled products are generally thinner. Steel plate: Cold-rolled plate is generally thinner.
For example, plates for automobiles; There are many hot-rolled medium and heavy plates, and there are similar thicknesses to cold-rolled, and the appearance is obviously different.
4. The hardness of Q345 steel The hardness of Q345 varies depending on its specific use. In general, the hardness requirements of Q345 are higher, and the hardness is also different according to different applications, processing techniques, use methods and other factors.
Second, what is the material of cold drawing?
1. Cold drawing does not refer to a specific material. Cold drawing is a processing technology of materials, for metal materials, cold drawing refers to the drawing of materials at room temperature in order to achieve a certain shape and certain mechanical properties.
2. Solution-strengthened superalloy is an 80ni-20cr solution-strengthened superalloy that was developed in the early stage, with a brief chemical composition, satisfactory thermal strength and high plasticity below 800, and excellent oxidation resistance, heat fatigue, cold stamping and welding process functions. The alloy is single-phase austenite after solution treatment, and the structure is stable during use.
3. What is the material of cold-drawn steel, which refers to the steel produced by a cold-drawn way, which is characterized by high precision, good surface quality, and very good texture, and cold-rolled steel is mainly used for the production of steel wire.
4. Wire rod: diameter 5-40 mm, coil-shaped, all hot-rolled products. After cold drawing, it belongs to cold drawing. Round bars: In addition to the bright materials with precise dimensions, they are generally hot-rolled, and there are also forged materials (there are forging marks on the surface). Strip: both hot-rolled and cold-rolled, cold-rolled products are generally thinner.
5. Cold drawing does not refer to a specific material. Cold drawing is a processing technology of materials, for metal materials, cold drawing refers to the drawing of materials at room temperature in order to achieve a certain shape and certain mechanical properties.
6. The materials of cold-drawn steel mainly include carbon steel, alloy steel, stainless steel and other materials.
Among them, carbon steel is one of the more common cold-drawn steel materials, which is rich in carbon elements and has high hardness and strength. Alloy steel, on the other hand, is composed of a mixture of metal elements, which can meet the needs of strength and corrosion resistance in different occasions.
