the problem is the metal is proprietary, so it tends to be abit harder to find information readily about the metal tubing products. Anyways....strida said:does anyone have any information including the:
of each of these materials iam soo stuck cant find anythin on the net about em
- strengths
- fatigue resistance
- resistance to bending
- ease in which they can be joined
thanks!My report is uploaded on the website
Note: some of the stuff in it is bullshit, be carefull if you have a really cluey teacher
lols one of the students in my school is handing in your direct report :mad1:My report is uploaded on the website

Really what a dick. Dont worry too much though about his mark, even if he beets you in this i guarentee he will do bad in the exams. Thanks for the rep haha. I would post my crane hook one up, which is form the lifting devices mod, but the site wont let me. So give me your email and i will send it to you =)lols one of the students in my school is handing in your direct report :mad1:
Pretty bs though, he said he cbf changing it...plagiarism to the max for hsc GG. I've used your report for a lot of referncing though, added you in the acknowledgement section too :uhhuh:
Note: No it is not me.
If you still have the report could you please send it? Engineering has pretty much stayed the same in the HSC for almost 20 years. I would appreciate if you could send it.My report is uploaded on the website

Thanks, the info on welding helped out quite a bit.Reynolds 853 is a low-carbon steel alloy containing manganese, chromium, molybdenum, copper and silicon. 853 tubes are manufactured in very thin wall thicknesses, like 0.5 mm to 0.4 mm. They are weldable by conventional tungsten-inert-gas (TIG) welding and gas-metal-arc-welding (GMAW). Tubes are seamless (no joints) and cold worked to increase the tensile strength by work-hardening. Reynolds 853 tubes are also available in the quenched and tempered condition.
The resistance to bending of a steel tube is a function of the Ultimate Tensile Strength (UTS) and the geometry of the tube (diameter, wall thickness and ovality).
There is only so much that the tube manufacturer can do to reduce fatigue cracking. Fatigue resistance of steel bicycle frames is a function of the quality control exercised during frame manufacture, in particular elimination of any sharp corners or notches that act as stress raisers, careful blending of welds, and double-butting of tubes so that extra thickness is provided at the joints where it is needed most. Reynolds 853 tubes are double-butted.
The chemical composition of Reynolds 853 is fine-tuned to the rapid thermal cycle of TIG welding to produce an austenite to bainite phase transformation in the heat-affected zone (HAZ) upon cooling between 800oC to 400oC. This ability to air-harden in the HAZ gives frame builders an economic advantage, and removes the need for any subsequent heat treatment.
Here is a chart taken from Reynolds website comparing the mechanical properties of their products. Notice that the stiffness (Young's Modulus) of steel alloys are all the same. That is because Young's Modulus is determined by the iron content and not by the alloying elements or the heat treatment.
