Steel group: Low carbon steels
Properties: Hybrid Steel is a low carbon steel containing a number of carefully controlled alloying elements, most importantly nickel, chromium, aluminium, molybdenum and vanadium. These enable it to develop its full properties after aging at elevated temperature (500–620°C). The chromium and aluminium content also improves corrosion resistance. The variant 197A is offered under the name Hybrid Steel 50 and the variant 297A is offered under the name Hybrid Steel 55 and the variant 397A is offered under the name Hybrid Steel 60.
Applications: No data
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Hybrid Steel 55, 950°C /45 min, hardness 450 HV, air or oil. Hybrid Steel 60, 1020°C/45 min, hardness 550 HV, air or oil.
Aging: See the diagrams.
Diagram note: Ac1=800, Ac3=950 C, Ms=350 C.
