Reynolds 853
The Reynolds 853 is a steel alloy created by Reynolds Cycle Technology, a manufacturing company based in Birmingham, England. It is composed of several elements solely including iron, carbon, chrome and molybdenum but also includes silicon, copper and manganese.
The Steel’s physical properties include a stiffness level similar to mild steel. With the addition of chrome and molybdenum the steel can be strong enough to butt or be thinned down in the middle, thus making the material lighter.
It has an excellent strength to weight ratio obtained from heat-treatment used in its formation. The heat treatment used for this steel does not use quenching rather uses air cooling or air hardening. This results in the steel having a finer grain and raises the yield strength in the material. Subsequently due to air hardening the material’s strength increases as the materials temperature cools. This unique air hardening property of Reynolds 853 provides additional stiffness through reduced micro-yielding at the joints, allowing stiffer products with excellent fatigue strength. This gives it an added resistance to all loads put on it and a resistance from damage.
In assembly Reynolds 853 steel is suitable for TIG welding and brazing, using lugged or lugless construction. The production process ensures tight tolerance, gauge tubes. The strength to weight ratio of 853 is close to that of quality titanium frames. It however can not be brazed.
The cost of the material can be relatively cheap once equipment used for making the product is obtained, i.e. casts, assembly lines, elements, etc. Maintenance to production equipment is the only other factor needed to take into account
Reynolds X100
Like the 853 steel alloy, Reynolds X100 is a product of Reynolds Cycle Technology, based in Birmingham, England. It is an aluminum alloy composed of both aluminum and lithium. The material was derived from aerospace projects and commonly
