AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components,like axles,shafts,bolts,gears and hydraulic applications.Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content.42CrMo4,1.7225,DIN,AISI,Alloy Steel Translate this page42CrMo4,1.7225,DIN,AISI,Alloy Steel .STEELMAX Steel Story .42CrMo4 0.42% 1% .Molybdenum .42CrMo4 DIN-EN . . 42. 0.42%
AISI 4140 is a chromium molybdenum quality alloy steel.AISI 4140 is primarily supplied in the hardened and tempered condition to 18-22HRc range.AISI 4140 offers good ductility,shock resisting characteristics combined with resistancee to wear.AISI 4140 is suitable for a variety of applications in the oil and gas sector.AISI 4140 PipesA519 AISI 4140 PipesAISI 4140 Alloy AISI 4140 Seamless Pipe is tubing made to the pipe schedule.Alloy pipe in the power industry generally refers to A335 material,but in the oil and gas market,4140 Pipe is used.This product is made to the pipe schedule but uses A519-4140 as the controlling Seamless specification.
Alloy steel 4140,hot rolled heat treated round bar AISI 4140 SCM440 42CrMo Cold drawn steel bar steel shafts.AISI4140 cold drawn steel bar; CD 4140 / 4142 alloy bar's chromium content provides good hardness penetration,and the molybdenum imparts uniformity of hardness and high strength.This alloy responds well to heat treatment.

Therefore,these JIS SCM440,SAE 4140 and 42CrMo alloy steel pipes are used in the form of the steel skeleton in large buildings,stadiums,bridges,and large supporting structures.In the same way,these are also important in the manufacturing of smaller equipment like bolts,nuts,screws,and many more.
