I work for a company who bends/forms large heavy structural steel members (HSS Tubing, WF Beams, Channels, Angles, etc.) on 3 roll section benders often referred to as angle rolls. Most if not all of these machines are Mfg'd in Europe. Link
These machines use large cylindrical dies turned/cut...
@EdStainless
looking further into these alloys 410/420 are Martensitic and Nitronic's are in the austenitic family? Ni-Resist is an Austenitic Ductile Iron...The difference between the two martensitic and austenitic is the corrosion resistance? And isnt martensitic stainless very hard and less...
After much thought research and consideration, my team did agree that the Ni-Resist suggestion was an ideal alloy for our parts....The problem now is who can we get this casting from....The only foundry i found that poured Ni-Resist in the size we need and was willing to do just a single part...
Yes certain surfaces will require machining after casting. We have also begun to consider an austenitic stainless in place of the Ni-Resist Cast Iron if we are unable to find someone to produce for us.
Question with respect to casting vs forging. In talking to these foundries, making a casting...
Hey guys! Hope everyone is doing well today! So in reaching out to a handful of Foundries I am coming short of someone who is constantly producing Ni-Resist Ductile Cast Iron or someone that can sand cast in the size we need. Dura-Bar produces a Ni-Resist but it is a flake graphite. Any...
Yes these parts are of decent size. And if this machine works out there are talks of building an even larger machine! These are all very important considerations to keep in mind. There is an automated high pressure lubrication system pumping grease into grease ways between the eyeball and the...
Wow you all are great! Thank you for the responses on this.
Heat input to these components will be minimal. The machine is an open frame design. The elevated temps are introduced into the steel by way of induction coil...worked then quenched with water to cool/temper. This assembly is after...
@TugboatEng THANKS! For the reply!
Semi corrosive environment.... As these components will be metal and possibly out a carbon steel alloy, rust/corrosion was a concern. The machine works steel and is done so at elevated temperatures. Water is used to quench the steel being worked and as a...
Take a look at the image. I have 3 components making up an "EYEBALL" assembly. The 2 most important are depicted. We are just about ready to cut/machine parts but we need to make a call on what alloy/grade of metal we will be selecting to machine these components from. These components are...
