  • Wanted

    I have a small project in mind that will require a piece of stainless steel shaft that is 2" in diameter and 4" long. If one of you fellows could sell me a piece I would really appreciate it. I would like something that is easy to turn, mill, drill and tap. Please contact me through the new e-mail address in my profile.

    BTW, the e-mail that my server provides (the old address) is very unreliable so I signed on with Google Mail which is much better. Gmail has provided me with 50 invitations to send to others who would like to sign on. If any of you would like an invitation just send me a note to my Gmail address.

    "Stainless" covers about 400 alloys. Do you mean austinetic? Ferritic? Do you need corrosion resistance, heat-treatability, strength, what? What's your application?

    There are alloys that are free machining but that's a relative term. Most of them are tougher than mild steels and a good many annealed alloy steels. You can't add a significant percentage of nickel and chromium to a steel without cranking up its physical properties.

    Tells us what you're going to make from this hunk of stainless and maybe we can advise you on an alloy that best suits your purpose.

          I just checked out the Google mail privacy policy. They have backed off from the universal search. They do however examine your mail in order to target ads to you.

            This outfit http://www.machinist-materials.com/ may have something. (I've never had occasion to order anything from them, but they look reasonable.)

              George,
              I may have a piece of stainless propeller shaft from a yacht, no idea the alloy number. I'll have to measure it, but if its about the size you need you can have a 4" piece if you want to pay shipping from South Florida. Contact me at my posted e mail address if interested.

                Geez Forrest, austinetic???????, I can't even find that one in the dictionary

                All I want is something that won't rust.

                  I have ordered from them and won several of their ebay auctions. Good guys that always combine multiple orders and only charge actual shipping.

                    Ferritic
                    Magnetic stainless steels that have a low carbon content and contain chromium as the main alloying element, usually between 13% and 17%. It is the second most widely used stainless steel. Ferretic stainless steels are generally used in automotive trim and exhaust systems, hot water tanks, and interior architectural trim.

                    Austenitic Stainless Steel
                    Non-magnetic stainless steels that contain nickel and chromium sufficient to develop and retain the austenitic phase at room temperature. Austenitic stainless steels are the most widely used category of stainless steel.

                      Thanks, I definitely need non-magnetic.

                        Side topic: Out of those 400 or so stainless steels, will any of them rust?

                        I got some Sheffield tools. (Sheffield seems to have nothing to do with England in this case. Sheffield is being used by Great Neck as a name for a line of their Chinese made tools.) Right where one of them is stamped 'STAINLESS STEEL' it's rusting.

                          This is what I've found.
                          we are talking "red" rust here.
                          non magnetic ss will not rust.
                          slightley magnetic ss will just get slight surface rust if left outside.....not sure about submerged.
                          think the more magnetic it is the more it will rust. (red rust)
                          as for corrosion resistance in different chemical enviroments ..I dont know...I'm no specialist .only an observor.

                            If stainless is worked with an abrasive that has been used for mild or high carbon steel then it will rust, something to do with contamination.

                              Had a bunch of 416SS left out side it rusted big time but when heat treated it hardly rusted at all, is a free machining type cuts well even after heat treating.You really need to get the 303SS it cuts easy, will not rust can be polished etc.
