- Reynolds 531
Reynolds 531 is a
brand name , registered toReynolds Cycle Technology ofBirmingham in theUnited Kingdom , for a manganese-molybdenum, medium carbon steelbicycle tubing.Introduced in 1935 and for many years at the forefront of alloy steel tubing technology, 531 tubing has been replaced and superseded by ever more complex alloy mixtures and heat-treatment/cold work cycles as Reynolds has continued to compete with other manufacturers of steel for the bicycle industry.
The approximate alloying composition of 531 tubing is 1.5% Mn, 0.25% Mo, 0.35% C, and is similar to the old British BS970 En 16/18 steel. Its mechanical properties and response to heat-treatment are broadly similar to the AISI 4130 standard alloy steel, also used for bicycle frames, among other applications. This material was used to form the front subframes on the famous
Jaguar E-Type car of the 1960s.Reynolds 531 is now only available to special order. But in the past was used by the
Raleigh Bicycle Company ofNottingham, England for their racing cycles.ee also
