AISI 4140 Pipe

4140 Tubing

4140 Seamless Pipe

AISI 4140 is a low steel alloy that consists of manganese, molybdenum and chromium. AISI 4140 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. There are very few grades of steel that have the capacity to match the usefulness and the versatility of AISI 4140. Material properties of AISI 4140 include it having superb ductility, superior toughness and in tempered condition or quenched condition, it shows excellent wear resistance. AISI 4140 has a Density of 0.284 lb/in³ (7.85 g/cm3) and it has a Melting Point of 2580 °F (1416 °C).

4140 steel uses are many because of its properties and characteristics. AISI 4140 has high impact resistance, high fatigue strength, superb torsional strength, excellent toughness and very good abrasion. AISI 4140 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.

AISI 4140 steel tube corrosion resistance is excellent because of the presence of molybdenum and chromium in it. The molybdenum in AISI 4140 is very useful as it helps immensely in the resistance of corrosion due to chlorides. The manganese that is present in AISI 4140 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 AISI 4140 combines with sulfur and improves the machinability of the material, also making the process of carburizing much more effective.

Carbon steel is a large category of steel that encompasses many varying chemical compositions. Each type of carbon steel requires different considerations when welding. For example if you choose Low carbon steel to weld which is typically the most readily welded steel in a room temperature environment. These low carbon steel suitable for welding include C1008, C1018, A36, A1011 and A500. Medium carbon steel such as C1045 typically requires preheat and post-heat treatment to avoid weld cracking. High carbon steel is even more prone to weld cracking than the other two groups of carbon steel. Welding high carbon steel will most likely require very thorough preheating and post-heating processes to avoid this. It could also require special welding filler metals.

AISI 4140 Pipe welding is used extensively for pipe welding, aerospace, aviation, biomedical implants, fabrication of race cars, choppers, etc.
