Is Dom stronger than HREW?
The difference between the HREW (hot rolled electric welded) and DOM (drawn over mandrel) is strength. This process creates a tube that has a yield strength of around 70ksi. The DOM is simply stronger, can take more punishment and is best suited for use against rocks.
Is Dom stronger than ERW?
DOM is typically more expensive and is considered a premium product compared to ERW by some fabricators. In a typical roll bar or roll cage you likely won’t find much difference in strength as both have nearly identical strength characteristics.
Is Dom stronger than pipe?
Pipe doesn’t have the strength of DOM. DOM is typically 1018 steel where pipe is most likely 1010. I have seen people use pipe for cages. I have used HREW tube which isn’t as strong as DOM and it worked fine but I had to replace pieces everytime I rolled cause it would deform pretty easy.
Is chromoly stronger than Dom?
From the research I have done, chromoly is generally 20-25% lighter than DOM. The reason for this is only because chromoly is stronger so you can use a thinner wall tubing and have the same strength.
What’s the difference between a DOM and a hrew?
The HREW is basically mild steel with a yield strength of around 40ksi. The DOM is the same material put through a secondary process where the tube is cold drawn over a mandrel which produces a more consistent and stronger tube. This process creates a tube that has a yield strength of around 70ksi.
What’s the difference between a DOM and an ERW tube?
The product will come in an “as-welded” condition, (often called – flash-in condition) referring to when the flash from the weld is left on the inside of the tubing, it is not normally removed or controlled during the ERW tube production process. Technically, DOM is not a type of steel tube, but rather the process in which the tube is finished.
What’s the difference between a DOM and a mandrel?
(DOM) Drawn Over Mandrel Technically, DOM is not a type of steel tube, but rather the process in which the tube is finished. It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel.
What’s the difference between crew and hrew steel?
This product is typically available in Cold Rolled steel (CREW) for 0.060” wall and lighter and Hot Rolled steel (HREW) for 0.083” wall and heavier.
