SA 516-70, welded with 7018.

1/8 welding rods are a good all round rod for flat, uphill, overhead and vertical positions. 7018 is a 70,000 pound rod. Meaning, 1 inch of weld will hold 70,000 pounds of pressure.

SA 516-70 is used for all kinds of industrial applications - everything from pressure vessels to heat exchangers

How do you hang 70,000 psi from something?

really? You take something that weighs 35,000 lb and hang it from something that has 1/2 in^2 cross sectional area.

AISI 4140 can get you up to 135KSI with the right heat treat. Good metal for repeated impact loads.

Come on, man. You got certifications but you don't get your mistake? You used pounds as a unit of pressure. It should've been psi.

Is there such thing as a Units Nazi?

My point was, you can "hang" 70,000 psi (which you actually can't because you apply a force to achieve the stress) on any size of weld, whether it's a square inch or a square meter.

And my first post was to correct Texashiker's misconception about force and pressure being the same thing. I do love the natural reaction to throw out how much experience one has, though.

Usually with a cable or straps.

When your dealing with something that weighs 35 tons, its best to use a spreader bar and straps. I prefer straps because they do not roll like cables will. And before the straps break, you can see them starting to fray before hand. But then again, some people prefer cables.

Some of the vertical towers I worked on that went to Saudi Arabia, we used 2 overhead cranes along with some straps that were about 14 inches wide. The towers weighed a little over 100 tons each, and we built 2 of them. They were 11 feet 6 inches in diameter, about 100 feet long and 1.625 inches thick steel.

Back on topic please.

Before electric and air powered grinders became popular, chippers where used to remove burs from metal. The chippers where like small jack hammers with a metal cutting tip on them.

So the OP wants to know about chippers, and metal for industrial applications. The bad news is, chippers became outdated in the 1970s.

ahh, I didn't catch the psi instead of lb in his post. I thought you were just surprised that a square inch could take 70 KSI, that's why I mentioned 4140 that's quite a bit stronger. My bad.
