Im building a go cart.what kind of steel should i get for my fame?(like alloy,stainless steel,ect?

Question

i meant frame,not fame.

Answer 1

just use regular carbon steel tube.  if you are going for low weight get aluminum.

Answer 2

Stainless is only good for not rusting, I would suggest the lightest one,  but stronger steel on the front just in case of a crash.So you should use HSLA steel for the frame and reinforce the front with a strong type of steel like carbon steel.

Answer 3

4130 alloy steel tubing, as is used for race cars and aircraft, is the best. However, it requires considerable skill to weld. If you just cut and bolt, not so bad.

Conduit isn't that strong, but should be strong enough, and the weight probably isn't that critical. It has good availability and price.
