Precision Ground mild steel?

[Ken_Shea]

One of the problems with using 12L14, although it machines like a dream, it also is very susceptible to rusting and not particularly weldable if that is a requirement but don't believe there is any by the look of the picture.
That unit could likely also use thick wall precision ground tubing.

Kevin,
What diameter do you require?

There's another chapter to that book. True, Young's is accepted to be 30,000,000 psi for virtually all steel, but the difference comes into the alloy and heat treatment where elastic and plastic deformation occur (different stress/strain curves). Annealed 1010 and 4140 HT will bend just as easily, but the 1010 will take on a permanent bend at a much lower stress point than the 4140. It's stiffness versus springiness.

Thanks for all the replies. Tony, I even understood the "light" reading. I think I will go with the stressproof as that is reasonable in price and available.

For the beginner most places that sells steel has hot roll and cold roll.
Hot is soft... Cold is much stronger.
