MATERIAL
853 steel is Reynolds’ premium grade of ferrous steel. Renowned for producing light, stiff, yet supple frames, 853 is the frame builder’s choice when only the best will do.
Available in a range of lengths up to 850mm, diameters up to 44.2mm and a wide range of butt profiles 853 finds a home in the rowdiest of mountain bikes and the most responsive of road and gravel bikes.853 is an air-hardening steel. The benefits of this are particularly noticeable in the weld area, where, unlike conventional steel alloys, strength can actually increase after cooling in air immediately after welding. 853 is heat-treated to give high strength and damage resistance, and the steel properties allow thin walls to be used so that lower-weight but fatigue-resistant structures can be made.
Why Reynolds 853 steel works:
UTS: 1250-1400 MPa, density 7.78 gm/cc. The chemistry includes carbon, manganese, chrome, molybdenum, silicon, and copper. The interaction between the alloys results in a fine grain structure that forms with air-cooling without the traditional “quenching” (fast cooling in water or oil) process. High strength from bainitic phase steel after a series of cold-working operations.
Additionally, heat treatment to the 853 specification raises the yield strength for the entire tube, increasing dent and impact resistance.
Reynolds has two specific variations in 853 steel:a) ProTeam: the thinnest wall tubes made for road bikesb) DZB: for Double Zone butted tubes, which are particularly suitable for ATB and 29er frames. This helps reduce or eliminate the gussets normally required to pass the stringent EN fatigue testing standards.
