Hot-Rolled Steel & Machining Questions

Sep 24, 2006 · You can anneal the work-hardened skin on cold rolled, but it's a pain -- 1200 F in a heat treat oven for a hour per inch, and you have to wrap it in stainless foil or it will scale-up just like A36. If you're going to machine a large plate, I would suggest using hot rolled. Mill off (or sand-blast off) the scale, and you're ready to go...

Machining hot-roll steel - just complaining - Village Press

Jul 31, 2010 · This morning I squared up a 3" x 3" x 1/2# piece of hot-roll angle on the lather, by clamping it to a faceplate against another square angle that was store bought. I remember reading somewhere that hot-roll was in effect case-hardened by the production process. But I wasn't prepared for exactly how difficult it was to machine. It was throwing off painfully hot chips that kept burning my arm ...

Machining hot-rolled steel? Discover Live Steam Forums

Mar 25, 2008 · The steel I bought has a rough, dark finish that reminds me of cast iron, and slightly rounded edges. From what I can tell on the internet, this is probably hot-rolled steel, usually A-36. When I try to machine this (by abusing my poor little Sherline lathe with milling column), it feels the same as when I was machining stainless steel.

Hot Rolled Seamless (HRS) Steel Tubing - Hot Finished ...

Hot rolled seamless (HRS) tube (also known as HFS or Hot finished seamless) is a lower-cost product than CDS tube and is a good material for applications that do not require the close dimensional tolerances and quality of surface finish that CDS tube provides. If tight tolerances are required, machining is used to finish the product to exact specifications.

Machining - Rolled Alloys, Inc.

Machine tools should be rigid and used to no more than 75% of their rated capacity. Both workpiece and tool should be held rigidly; tool overhand should be minimized. Rigidity is particularly important when machining titanium, as titanium has a much lower modulus of elasticity than either steel or nickel alloys.

Cold rolled steel? The Hobby-Machinist

Oct 15, 2018 · Cold rolled does indeed machine differently that hot rolled steel, which is softer and tends to tear rather than cut freely and smoothly. The cold working of the metal makes it harder and more dense than HR. I disagree with the previous post that finishing makes no difference, that just the material makes a difference; cut a piece of HR, then a ...
