Problems solved by technology
It can be said that steel is the material basis of modern society. Most of the existing materials are easy to rust and fall off. The technical problem to be solved is to provide a new type of steel for cold work dies with good comprehensive wear resistance and tensile properties and long service life. Material, the main composition reduces or avoids the cracking of the mold, reduces the cost of production and use, prolongs the service life of the mold, and improves the performance

The invention discloses a steel material for a cold working mold. The steel material comprises the following raw materials in parts by weight: 15-25 parts of carbon, 10-20 parts of zinc, 10-12 parts of copper, 6-8 parts of tungsten, 6-10 parts of chromium, 6-8 parts of niobium, 1-3 parts of wear resisting agent, and 1-3 parts of curing agent; the main components reduce or prevent embrittlement and cracking of the mold; the production and use costs are reduced; the service life of the mold is prolonged; and the performance is improved.
Description
technical field [0001] The invention relates to the field of materials, in particular to a steel material for cold working dies. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.06% by mass. The chemical composition of steel can vary greatly. Steel containing only carbon elements is called carbon steel (carbon steel) or ordinary steel; in actual production, steel often contains different alloying elements according to different uses, such as: manganese, Nickel, vanadium, etc. Human beings have a long history of application and research on steel, but until the invention of the Belleville steelmaking method in the 19th century, the production of steel was a high-cost and low-efficiency work. Today, steel is one of the most used materials in the world due to its low price and reliable performance, and it is an indispensable component in construction, manufacturing and people's daily life. It can be said th...
