DINI17565-1968, Germany Chrome Iron
Chromium iron, also known as DINI17565-1968, is an alloy of chromium and iron used to produce high-temperature and wear resistant parts. The chromium content of this alloy can range from 2 to 5.5%, and its overall composition consists of about 94% iron, 2-5.5% chromium and 4-5.5% carbon. This alloy’s most common form is a martensitic matrix with a fine dispersion of carbides.
The high chromium content of this alloy offers outstanding resistance to oxidation, carburization and corrosion when used in high temperature operating environments. The properties of DINI17565-1968 make it especially suitable for applications such as gas turbines, gas and oil fired boilers, and hot air furnaces, as it is able to withstand exceptionally high temperatures.
The mechanical properties of DINI17565-1968 depend largely on the metal’s heat treatment procedures and the distribution of carbides in it. This metal often exhibits high tensile strength, resilience, and low-cost compared to other chromium alloys. It also has superior creep characteristics, while its unique balance of properties can also be used in certain elements of high-pressure machines, such as valves and gears.
The wear resistance of this alloy can be further increased by hardening and tempering, a process which involves subjecting the metal to controlled and carefully applied thermal treatments. Parallel and angular failures can also be minimized due to its increased hardness and impact strength.
Although DINI17565-1968 is lightweight, heat resistant, and possesses excellent wear resistance, it is also brittle and relatively susceptible to cracking when incorrectly welded or handled. It is therefore recommended that precautions have to be taken in order to minimize stress or prevent fractures.
Overall, DINI17565-1968 is an alloy of chromium and iron that has proven to be a durable, efficient and cost effective metal for many applications. Thanks to its wear resistance and excellent resistance to oxidation, this metal is extremely versatile, particularly in the areas of gas turbines, boilers and furnaces.
