1. Knowledge of welding material products
1. A: Welding materials include welding rods, welding wires, fluxes, gases, electrodes, gases, gases, gases, gases, pads, etc. QWhat is welding wire?A: When welding, it is used as a filler metal and at the same time is used to conduct electricity - called welding wire. There are two types: solid wire and flux-cored wire.
Commonly used solid wire type: ER50-6 (grade: H08MN2SIA).
2. The general name of the materials consumed during welding is called welding materials, referred to as welding materials;Such as welding rods, welding wires, metal powders, fluxes, gases, etc. Welding electrode: The molten electrode coated with coating for arc welding is called electrode, referred to as electrode;The electrode consists of a core and a coating (coating).
3. Welding: Through heating or pressurization, with or without filler materials, the process of combining two objects atoms to form an inseparable whole. Weldability: refers to the ability of homogeneous or heterogeneous materials to be welded to form a complete joint and meet the requirements of the intended use under the conditions of the manufacturing process.
4. Welding materials (complete knowledge of welding materials) The general term of the materials consumed in welding is welding materials, referred to as welding materials;Such as welding rods, welding wires, metal powders, fluxes, gases, etc.
Cover electrode: The molten electrode coated with coating for arc welding is called a welding rod, or welding electrode for short;The electrode consists of a core and a coating.
Second, M303 die steel is quite a domestic material
1. M303 plastic mold steel is an improved grade after referring to the excellent characteristics of German steel 2083 and 2316, and domestic materials cannot even surpass 2083, so there is no substitute.
2. Austria Bailu M303 superplastic mold steel It is a new type of corrosion-resistant martensitic stainless chromium steel, which has excellent toughness, excellent purity, corrosion resistance and wear resistance, and its cutting and polishing properties have been further improved.
3. What is the material of M303 and what is the material of M303 M30EXTRA plastic mold steel is a new type of corrosion-resistant martensitic stainless chromium steel produced by the Austrian Belle B Hler steel mill, which has excellent toughness, excellent purity, corrosion resistance and wear resistance, and the machinability and polishing performance have been further improved.
4. Does die steel 2510 need heat treatment 2510 is equivalent to what material is made in China 2510 mechanical properties: Hardness: hot-rolled or tempered HB20 Factory Condition: Soft annealed to HB23 German 2510 die steel Factory Condition: Soft annealed to HB23 Application: Suitable for cold pressing processing, row cutting, row head and shear die German 2510 die steel.
5. Austria Bailu M30EXTRA plastic mold steel is a new type of corrosion-resistant martensitic stainless chromium steel, which has good toughness, excellent purity, corrosion resistance and wear resistance, and the machinability and polishing performance have been further improved.
6. M303 mold steel plate is suitable for making transparent and opaque plastic product molds that bear high load, high load, and under the action of medium. M303 Mold Steel Material Supply Status and Factory Hardness: M303 Mold Steel Steel Bar Steel Plate Round Bar Steel Material Material The supply status of the module is pre-hard, and the factory hardness is about 290-330HBW.
