A519 4140 seamless tube equivalent material & EN grades are EN# is 1.7223, EN name is 42CrMo4, DIN is 41CrMo4, BS 970 is 708M40, UNI is 41CrMo4 and JIS is SCM 440.
A519 4140 seamless tube corrosion resistance is excellent because of the presence of molybdenum and chromium in it. The molybdenum in A519 4140 tubing is very useful as it helps immensely in the resistance of corrosion due to chlorides. The manganese that is present in A519 4140 seamless tubes is extremely helpful as it acts like a deoxidizer and it also increases the hardenability of the material. Plus, the manganese that is present in A519 4140 tubes combines with sulfur and improves the machinability of the material, also making the process of carburizing much more effective.
A519 4140 seamless tube application: A519 4140 tubing has high impact resistance, high fatigue strength, superb torsional strength, excellent toughness and very good abrasion. This steel has many applications such as connecting rods, steel ejectors, sprockets, torsion bars, tool holders, steel couplings, pump shafts, mold bases, holder blocks, forks, pinions, chuck bodies, drill collars, bolsters, motor shafts, crow bars, strippers, valves, fixtures, boring bars, lathe spindles, reamer bodies, tool holders, rams, conveyor pins & rolls, crankshafts, steel collets, milling spindles, steel conveyors and rolls, etc.
