What is Reynolds 631 tubing?
The 631 tubing was developed as a weldable tubeset with the characteristics of a 531 tubeset. It is air hardened so it was designed to be welded. 853 tubing is along the same lines, a progression of the 753 tubing designed to be welded. Just about any tubeset can be built into a harsh or comfortable frame.
What is 631 steel?
Reynolds 631 The alloy is a development on our famous 531 range with 10% higher strength. For cycling use, this provides tough, durable and comfortable frames particularly suitable for long distance riding, MTB and BMX . It has recently become available for touring and race fork blades.
What type of aluminum is used in bikes?
The 6061 aluminium alloy is traditionally used in the extrusion of tubes for bicycle frames.
What type of steel is used in bikes?
Steel is the most commonly used material in bike frames. Carbon or high-tensile steel is a good, strong, long-lasting steel, but it isn’t as light as its more high-tech brother, the steel known as chromoly. A workhorse of the industry, chromoly is a light, strong steel.
Is chromoly stronger than steel?
Chromoly is a chrome-alloy steel with a medium carbon content and . 8% – 1.1% molybdenum for strength. It is a steel that is stronger than carbon steel (more commonly used in bike manufacturing), so we can use thin wall tubing, giving you a lightweight frame that will last through years of riding.
Where are Reynolds tubes made?
Birmingham
Of all the cycling companies that have come and gone, one that has remained a steady fixture is Reynolds. The name has been synonymous with the British cycling industry since 1898, and it still manufactures tubing in its Birmingham factory today.
Where are Reynolds bikes made?
In a market place that’s experienced dramatic change, we’re proud that Reynolds remains British-owned and is still manufacturing products in Birmingham, where our story began almost 120 years ago.
Is Reynolds 531 still available?
Reynolds 531 is now only available by special order. The nearest available stock material is BS4t45 to Bs5T100 in accordance with BS6S100 conditions. (T45) Reynolds has superseded this tube set with a number of innovations such as Reynolds 753 and the more current 853.
Why Reynolds 631 tubes?
Why Reynolds 631 works: UTS: 800-900 MPa, density 7.78 gm/cc. As 853 in composition but tube strength results from the extensive cold-working of the seamless billet without a final heat-treatment. The TIG welded part of the tube still benefits from the air-hardening feature that results in a fine grain structure within the heat-affected zone.
Do Reynolds still make 531 frame tubing?
Reynolds make 531 frame tubing to special order only, as our innovative 631 air-hardening steel has allowed Reynolds to update this range Reynolds 631 – cold drawn.Following on from the success of 853, Reynolds have added 631 to the range of AIR HARDENING STEEL tube sets.
What is the difference between Reynolds 520 and Reynolds 631?
Reynolds 520 (note- all of the Reynolds tubing listed is butted): Reynold’s version of the standard butted Cro-Mo, their entry level butted tube set Reynolds 631: the next level up, air hardened, with higher strength and thinner wall thicknesses available
What is the difference between 631 and 853 tubing?
