Just make sure it's not from China.
A little fact that most people don't know is that while China can make high grade steel as well as most countries, all of it goes to their military and major construction projects. Most of the replacement parts and so on and consumer goods - recycled or second grade steel.
If the axles are made in China, they might as well be stamped steel or aluminum, as far as I'm concerned. (plus it's really not impossible to get all of the grit and grease out of there - just about 15-20 minutes per axle with the trick I mentioned)
Pet peeve of mine I guess, after having metal tear, bearings go out, and bolts just plain snap like a twig in all sorts of machinery from wheelbarrows and gardening tools to car parts.
