1018 is one of the most basic of mild steel alloys. but yes, it refers to the grade/classification of the steel.

 

Thats what i thought to ill probably get the pro 105 heavy duty bender towards the end of summer and if it bends it cool if it dosent bend it i will buy some thin wall

 

I agree. 1020 is DOM, so what you bought isnt DOM.

1018 is Cold Rolled which is better than hot rolled but not as strong as DOM.

The carbon content is .18% hence the 1018

Cold Rolled is used in sliders/bumpers/etc

DOM is normally always used in links and most of the time in shock hoops and other critical applications.

 

so im kinda confused did you go to your local scrap yard and get this or what. im wondering if i can do this at a place around here

 

1020 is the most common form of DOM they do offer it a lot of different alloys.

 

would 1018 be okay to extend my radius arms i am also going to plate the whole thing with 1/4" angle iron.

 

Anyone?

 

what size and thickness?

 

2" OD 1/4 wall

 

Can someone answer my question

 

Its called a phone book, open it up. We arent going to know whats in your area you have to do some leg work.

 

what would i look up? thats what im comfused about

 

Junkyard, steel, scrap yard. Open it up and start flipping through the yellow pages.

 

thread jacked
Its 2"od with 1/4 wall red ranger that answers your question and will be plated with 1/4" angle iron also.

 

holy *****, yeah that should be way fine. guys use 2" 0.120 wall for roll cages.... so yeah.

 

Yea that will be fine.

Thats cause rollcages strength isnt from the tube itself so much as it is the actual cage design. 2"x.25" wall is the smallest wall and tube diameter I would use for suspension links.

 

Thats what i was thinking its all in the disign and how everything ties together.
