What does the German brand BF refer to, such as 16MnCr5BF, 20MnCr5E

20MnCR5 carburizing steel, E carburizing quenching

20mncr5 Introduction:

20mncr5 is a kind of alloy structural steel, carburized steel, with high strength, toughness and good hardenability. The performance obtained after heat treatment is better than 20cr. The quenching deformation is small, the low-temperature toughness is good, and the machinability is good; But the welding performance is low.

It is generally used after carburizing, quenching or quenching. It is used for manufacturing and heavy-duty quenched and tempered parts with large cross-section and carburized parts with small cross-section, and can also be used to manufacture small and medium-sized parts with medium load and small impact, instead of 20crni, such as gears, shafts, spindles, friction wheels for transmission equipment, worms, sleeves of governors, etc.

20MnCr5 characteristics and scope of use:

It is a steel grade imported from Germany, which is equivalent to 20crmn steel in China, which is carburized steel and can also be used as quenched and tempered steel. The hardenability is good, the heat treatment deformation is small, the low-temperature toughness is good, the cutting performance is good, but the weldability is poor. It can be used as carburizing parts and quenching and tempering parts with large cross-section and high load, such as gears, shafts, worms, sleeves, friction wheels, etc.

16Manganese-Cr5 is an alloy material! China's market ** This material is relatively small, which is not a common material on the market. This is common in Europe.

16mncr5 belongs to the European standard "guaranteed hardenability carburizing steel", the implementation standard: EN 10084-2008

The chemical composition of 16MnCr5 is shown in the following figure:

In terms of chemical composition, 16MnCr5 is equivalent to the domestic grade "16CrMnH".

16mn CR5 is a German steel grade, which is mainly used in Volkswagen gear manufacturing in Germany. After the introduction of Fushun Special Steel Plant according to German standards, the production process is electric furnace steelmaking, molten steel mold casting into 3 tons of rectangular steel ingots, demoulding, using the red delivery process, directly transported to the 850 branch factory for furnace heating and billet opening. It was found during the production process that the ingots were poured after 2

5 hours of demoulding , about 650 80 0 temperature zone.

16MN-CR5 Executive standard: DIN EN 10084 is a steel grade imported from Germany, which is equivalent to 16CRMNH steel in China (refer to GB T 5216-2004).

According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. Steel is a material of a certain shape, size, and properties that ingots, billets, or steel are made by pressure processing. Most steel processing is carried out by pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.).

According to the different processing temperatures of steel, it can be divided into two types: cold working and hot working.

Steel is an indispensable important material for national construction and the realization of the four modernizations, its application is wide, variety, according to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products, in order to facilitate the organization of steel production, ordering and do a good job in management work, and is divided into heavy rail, light rail, large section steel, medium section steel, small section steel, steel cold-formed section steel, high-quality section steel, wire rod, medium and thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe steel, welded steel pipe, metal products and other varieties.

German standard ST52 is equivalent to Q345 in China, and the old grade is 16MNCR5 steel for cold-rolled work rolls.
