i got some 4140 1.5 dia. for my steering rod will it need to to be heat treated to keep it from bending or will it be fine as it is. I will not have hydro. assist, but the I do hav power steering. any info would help thanks.

:smokin: and:beer: what a life

no one on this sight knows the answer to this question! come on at least rip on the point. I thought I would at least get that from you guys. I guess that I will have to call a profesinal to answer this one cant depend one youal:rasta:

I don't think you'll have a problem but it's not the BEST to use...:D :flipoff2: :beer:

Here's the problem:
90% of the users here (Myself included) don't know shit about metallurgy. You have to wait for a few of the college kids or working professionals to get online before you will get a TRUE answer. Until then, have a :smokin: & a :beer: and catch some :zzz: :zzz: ...:)

You need to delete this and start over.

Misspelled words in the title and you not looking for steering help your looking for 4140 help might get you a better response!:rolleyes: :rolleyes: :rolleyes:

Are you wanting to park the truck on it, or use it as a battering ram????

I've made several tie rods out of 1-1/4 1018 (mild steel) that includes two run on a full size blazer with Rockwells, 44" TSL, and a 2" hydraulic ram. He did manage to bend the first one, but he rolled a large rock (aka bolder) under it. :p

4140 is a 'chromoly' series, it's VERY tough! Don't try to heat treat it, you'd rather it bend than BREAK :nuke: :D.... As it is now, most likely the heims or tie rod ends will break first. ;)

thanks for the input guys I will keep it in mind.

Can't find any specific #s but both yield and breaking strength for un-heat treated 4140 should be a bit higher than HREW, but toughness (amount of deformation before breaking) should be a bit lower, due to the high carbon.
