1.8550 - AT A GLANCE
What kind of steel is the 1.8550?
The steel grade 1.8550 also known under its chemical discription 34CrAlNi7-10 is a nitridable steel and will be delivered in the tempered condition. This steel grade is being used where high wear resistance is needed. Nitriding gives this grade a higher surface hardness which can reach approx. 950 HV (approx. 68 HRC). The 1.8550 finds its use in machine and plant engineering but also in the automotive industry as well as for plastic processing operations.
Properties
The 1.8550 is an CrAlNiMo alloyed steel when processing plastics as well as for the automotive industry.
This steel grade is delivered in the tempered condition and gets used often for parts in mechanical engineering. For even better wear resistance and a better corrosion resistance the 1.8550 can be nitrided. The nitrading process can achive a nitriding hardness of approx. 950 HV (approx. 63 HRC).
