DOM vs HREW
What's the difference between DOM and HREW?
The main difference is strength. HREW (hot rolled electric welded) metal is milder steel, which is still plenty strong, with a yield strength of 40ksi.
DOM (drawn over mandrel) steel is the same material which does not have a welded seam, with a yield strength of roughly 70ksi.
Another difference between them, DOM is more expensive of a material to use, so any DOM orders will be made to order, where as we try to keep inventory in stock made from HREW. Usually we can get HREW sliders out quicker than DOM.
