Chromoly steel is medium-carbon ultrahigh-strength low alloy steel that gets its name from abination of the words “chromium” and “molybdenum” – two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steelease in cost.Oct 19, 2019 · Both carbon steel and alloy steel are considered alloys, but one differentiates from another by the fact that alloy steel contains non-metals such as manganese and aluminum in significant quantities, while carbon steel only contains a trace amount of them. The nonmetals will give steel special characteristics.Alloy steel may be defined as steels to which elements other than carbon are added in sufficient amounts to produce improvements in properties. The mostmon alloying elements added to steel are chromium, nickel, manganese, silicon, vanadium, molybdenum, tungsten, phosphorus, copper, titanium, zirconium, cobalt, columbium, and aluminium.Nov 08, 2021 · The AL3 2.5V alloy (containing 3% aluminium and 2.5% vanadium) is the mostmon grade used for titanium frames. 6AL 4V tubing is notably stronger – and more difficult to work with, as a result – and is sometimes used for high-performance frames or individual areas where stiffness is key, such as the head tube and bottom bracket sleeve.
