Mudsimus Posted July 3, 2007 Share Thats one stupid experiment. Like the one guy said "the strengh of the tube is in its ability to support weight vertically, not horisontaly. Link to comment Share on other sites More sharing options...

WorcesterWheelers Posted July 3, 2007 Share Anybody notice that the Van reversed to just before the cement cerb before atempting to ride over the Ti tubing..... Link to comment Share on other sites More sharing options...
MintSauce Posted July 3, 2007 Share Tensile strenght is more important than compression strenght in bicycle design. Anyone heard of the new Reynolds 953 stainless steel tubing? http://www.reynoldscycles.co.uk/steel953.html TUBING: Materials Q- What is 953? It is a maraging stainless steel, manufactured for Reynolds by Carpenter SpecialtyAlloys, USA. This material undergoes a double vacuum remelt process to get achieve the necessary properties and purity. It has a very low carbon content, which has an advantage that machinability compared to e.g. AerMet 100 which is improved due to low carbide content. Key features are:? Made from welded, cold-drawn tube with a highly homogenous welds to avoid a potential weak point (manufactured by a specialist aerospace weld mill). Although a departure from Reynolds' preference of using seamless materials for high-end tubing, the cost factor would make seamless material very expensive for a steel frame although this remains a future option. ? Ultimate tensile strength - 1750 to 2050MPa depending on process used.? Yield strength 1500-1900 MPa depending on the combination of cold-working, butting, and ageing temperature. (1500 MPa is approx. twice the yield strength of Cold-worked, Stress relieved 3-2.5 titanium). ? Stiffness Modulus (E) is 200 GPa, similar to other steel alloys. Although Reynolds do not have frame design expertise, we assume that if higher stiffness is required when lighter tubes are used, advantage can be taken of the higher strength by using slightly oversize but thin wall tubes with a lower overall weight.? Can be TIG welded with AWS ER630 wire or silver brazed using recommended filler wires. ? High tensile / impact strength and fracture toughness? Corrosion resistance superior to type 410 stainless steels. Note that under some conditions e.g. sulphuric acid, prolonged submersion in sea water 953 will show signs of pitting and corrosion. In use near e.g. coastal areas, staining can occur on the surface, but these can be easliy removed as for stainless cutlery taken out of a dishwasher.? Cold worked butted wall profiles from 0.65mm down to 0.3mm (e.g. .65/0.4/0.65, 0.5/0.30/0.50mm) depending on diameter? Full range of stainless steel fittings / BB shell / head tube will be available in compatible alloys including 953 BB shell, 953 rear drop-outs. ? Tube diameters 28.6, 31.75, 34.9 & 36.4 mm for the main triangle Also see http://www.ifbikes.com/frames2/953.shtml Link to comment Share on other sites More sharing options...

no.one.knows Posted July 4, 2007 Share well im not exactly planning on leaving my carbon bike conveniently parked under a 2ton truck. but very interesting thank you! i just dont have the money for a titanium bike and besides, carbon looks way hotter!

AndreZA Posted July 4, 2007 Share but very interesting thank you! i just dont have the money for a titanium bike and besides' date=' carbon looks way hotter![/quote'] You say WHAT? I guess you think Paris Hilton is also hot then? The only time carbon looks hot is when it's bonded to a Ti frame in a Titus Exogrid or Merlin Cielo.
