Reynolds 531
Reynolds 531 is the brand name for steel tubes made by Reynolds Technology Ltd. in Birmingham , England , which were used for various chassis designs. The tubes are made of steel with a medium carbon content, which with manganese and molybdenum alloyed. The name is traced back to the original proportion of alloy elements (5: 3: 1).
History and technology
The tubes were used in the aerospace industry from 1935 and in other industries for various high-quality frame structures from the late 1950s. Frames and forks for commercial racing bikes, delivered with a wall thickness of 1.6 mm to 2.3 mm, became internationally known. Six Tour de France winners competed with Reynolds 531 frames from 1958 to 1991. Motorcycle frames made of Reynolds 531 tube were built by BSA , Hesketh and the frame builders Seeley and Rickman , among others . Reynolds 531 tubes were also used in sports cars, such as the Jaguar E-Type , as well as in airplanes and the record-breaking Thrust2 . Reynolds 531 tubing is still shipped to order today.
Composition and strength
The alloy of the tubes consists of 1.25 to 1.45% manganese, 0.15 to 0.25% molybdenum, 0.23 to 0.29% carbon , 0.15 to 0.35% silicon, and a maximum of 0 , 45% sulfur and phosphorus. The ultimate tensile strength after brazing was found to be 686 N / mm².
"The values show how well this material retains its strength after brazing - a blessing for every frame builder."
