Landing Gear Alloys adapted for blades?

[SpyderEdgeForever]

Sal and all,

The idea came across to me: since Aerospace vehicles need very strong but resilient alloys to make into landing gear, is that a good possible source for new knife blade alloys?

Google:

"Landing gear uses high-strength, tough alloy steels like 300M, 4340, and maraging steels, or precipitation-hardening stainless steels like Custom465, chosen for their immense strength, impact resistance, and fatigue life to handle massive loads, though titanium alloys are also used for lighter options. These steels are often modified (e.g., 4340M) for even better performance and require specialized, heavy-duty machining and heat treatments to achieve required properties for safety-critical components like main struts, axles, and cylinders. "

No longer paging anyone. Sensible discussion below.

Any of those properties required for aircraft landing gear involve holding an edge while cutting stuff?

Being strong or corrosion resistant doesn't guarantee it'll also hold an edge.

No, of course not. Which OP would have found out immediately if he was actually looking for answers. Google will tell you straight up that 4340 is too soft.

300M can hit 56 HRC. Possibly good enough for axes.

I think we can turn off the Larrin bat signal for this thread

A company that makes landing gear for P40 warbirds asked me this question.

My answer?

The knife shaped object will look nice, but edge holding will be mediocre, and corrosion will be more than what you desire.

If that stuff worked great for a knive blade and how much lighter weight it is, we would have been building rifled barrels from it.

It would cut down the weight on pistols and rifles greatly. They just won't hold the sharp edge of the rifling in a barrel. Darn shame it's not just that easy though.

Air bus uses titanium components in their landing gear whereas domestic airlines use mainly high strength steel. High strength steel would not work, very susceptible to corrosion, easily burned with the machine process and too soft. Commercial airlines shotpeen the landing gear parts to strengthen them. After shotpeen, they are grit blasted with aluminum oxide media to remove any risidual iron so there is no galvanic reaction. After they are grit blasted they receive a unbright cadmium plating followed with a chromate conversion to further reduce corrosion susceptibility. Following the plating process they receive a hydrogen embrittlement relief bake to release any hydrogen gas from the plating process. Following plating, paint is applied prior to bushing installation and build. Long explanation to say high strength steel would not be a good choice.

Landing Gear Alloy blades?
With scales made from Aircraft Grade Aluminum?
I'm sure there would be gas station customers who would be all over that.

[SpyderEdgeForever]

Thank you all for helping me see that strong does not automatically equal good edge.

[Red Leader]

Perhaps a whimsical idea, but I think some of these responses have been a bit harsh.

I'm most curious about what Spyderco might be able to do with S290, personally.

Nobody has spare cash after the gas station for knives Having a car has become the new mortgage.

I hope Boeing doesn't have this guy taken out for blowing the whistle on landing gear steels.

Would H1 and H2 steel make good landing gears?
