Not quite the same materials but I can think of one hard to hard connection. The rear brake tubing which clips over the rear axle connects directly into the wheel cylinders. That is typically steel to cast iron so both are hard. Whether one of those would be considered a softer material is a question. I'm trying to remember if the fuel tank outlet swaged into the tank is steel or brass but I think at least one of my Packards used steel. If so there would be a steel to steel application. Aren't most high pressure hydraulic connections such as used in lift cylinders steel to steel?
