20CrNi3 is a kind of chromium-nickel alloy steel with hardness between HB180-240 and yield strength≥800Mpa. It is mainly used in the manufacture of medium-sized and small-sized plastic moulds for die-casting, and for the production of various non-ferrous metal alloy die-casting dies.
20CrNi3 steel has good wear resistance and toughness, and can be used in a variety of applications, such as die-casting, extrusion molding, deep drawing, hot pressure re-working, cold heading, spinning, etc. It can also be used in the production of standard parts, such as screws, nuts, washers, shafts, spindles, sleeves, etc. 20CrNi3 steel also has a good cutting performance, which makes it suitable for the production of tools with complex shapes and contours.
20CrNi3 steel has a hard and tough matrix, which allows the production of dies with good surface quality and dimensional accuracy. The alloying elements of these alloy steels can be adjusted for the production of dies with different properties. With an appropriate choice of alloying ingredients, 20CrNi3 steel can be produced to meet the demands of different working environments.
20CrNi3 steel has good corrosion resistance and oxidation resistance. It can be used in damp and corrosive environments, such as salt water and acid solutions. It can also be used to produce components with greater durability, such as pressure vessels, heat exchangers and other components for corrosive media. It can also be used for the production of marine fittings and components.
20CrNi3 steel has good fire resistance and can be used in applications which involve high temperatures, such as furnace and chamber chillers, heating furnaces and other high temperature applications. It also has excellent thermal shock resistance and can be used to produce components with high temperature and thermal shock resistance, such as exhaust valves and oil and gas pipelines.
In conclusion, 20CrNi3 steel is a versatile and high performance alloy steel, which can be used in the production of a variety of components and components for all kinds of applications. It can be used in the production of all types of tools, dies and machine parts, as well as various components for high temperature, corrosion resistant environments and other demanding working conditions. With its good wear resistance, high strength and corrosion resistance, it is an excellent candidate for a range of application areas.
