Is it Cast Iron or Cast Steel? 5 ways to help you identify before making your welding repair! One of the first steps in making a cast iron welding repair is to determine if it is in fact cast iron. I explain and demonstrate 5 easy ways to help you identify if it's cast iron or cast steel. ⇨ SUBSCRIBE to Brandon Lund DIY Builds: https://www.youtube.com/brandonlund THE TOOLS & GEAR I USE 🔴 https://www.amazon.com/shop/brandonlund MORE CAST IRON WELDING VIDEOS: https://www.youtube.com/watch?v=9pMbeG7QVZA&list=PLfbf78fMz9VpweFv4IqUfrrNV6Vvro7Cd Any commission earned from the above Amazon affiliate links all goes towards helping to support my channel.

In its molten state cast iron flows better than cast steel. A cast iron piece could be much more detailed than a cast steel piece. In a cast iron part you would see square corners where a cast steel part would have more rounded corners. Cast steel could be used in parts that need more structural integrity because it is more malleable, that would be the opposite for cast iron because it is more brittle. Hope this helps a bit?

You always have such great comments Richard. Thank you. These are the comments that add to our community!

I appreciate the multiple methods to check. I recently purchased some replacement lower shock brackets that are clearly cast. But, I wanted to do some modifications to them, specifically some welding. I was afraid they might be cast iron. But, after watching this, I have confirmed they are cast steel. Thanks!

Glad I could help! If its cast steel now you can just weld it with whatever process you choose :)

I never buy them. I use old ones.

Okay wildman... Before you fix that pan with a coat hanger and a torch I wanna know if cast steel and cast iron can be welded together. Using 1960's technology. May have to go run my spark test at night on account of I can't drill a hole, it's too rusty to file and there's no break to look at the grain. There is grain in steel and it will look different depending on the break with or against it. I've seen it look granular like cast iron before. Thanks for your videos and please... I learn as much from watching an error as I do from watching a correct job.

Cast iron and steel can be joined using 1960's technology. Its beyond my time but folks have been doing it successfully for decades. If you have no ability to test your part than you are limited to trying to weld it and hoping for the best. Cast iron can be a crap shoot to weld depending on its carbon content amongst other things.

Great info ,I have a giant cast iron ( I will test it now) bowl maybe 4 foot across 2 1/2 deep guessing 1 in thick with about a foot long bad crack maybe some day I will try to fix it ,l think it was used to to heat water to dunk pigs and scrap off the hair .

+mashed-\ /-out Because they are affordable and not everyone is wealthy. It makes perfect sense to me. I own Wilton and cheap vices and they both have their place in a fabrication shop.

Why would someone own a damn China inbread cast iron vise? Jeezus Phuc over?

That thing must weigh a ton!

Brandon, you are going laugh at this, I broke my vise, now who breaks a vise, me used a snipe tighten up on some bar and snap. so now to weld it back I will be using cast 80 or 90 rods. Just in case I bought a new vise and heavier.
Brandon Lund (4 months ago)
Cast rods is a good choice for a vise. Those handles are just too short! 😂

Soak that pan in a bucket of used motor oil and do some welding on it for a real world test! = )

​@UCqbOYHe7tmehqnQJnYka-5w I actually have a lot of experience with nodular iron. It's often referred to as Ductile Iron. I've laid miles of Ductile Iron pipe back in the day.

+Just ME Onlyme I think that's a great idea. At first I started out this series with a cast iron exhaust manifold because they can be hard to weld because of exhaust contamination, but a lot of folks will claim that it is made of cast steel (even after all the testing is done proving otherwise) like they did with the exhaust manifold. That's why I decided to keep it fool proof and I picked a cast iron pan.

I'm going to try and do one better, I'm looking for an engine block! Dirty enough for ya! Cheers brother!

Good stuff. From certain things I’ve seen cast steel doesn’t take solid mig as well as stick or flux core w or w/o gas
Brandon Lund (3 months ago)
Thank you! I've had limited success with solid wire. Cast can be fussy
