- IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingStress RelievingAnnealingNormalizingNitridingAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition. The AISI 4140 cold finished annealed chromium-molybdenun alloy Grade Guide:AISI 4140 Steel Metal Supermarkets - Steel Jun 19, 2018 · AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel. The additions of chromium and molybdenum are why AISI 4140 is considered a
AISI 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered. 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. Annealed 4140 Cr-Mo Steel ::MakeItFromMay 30, 2020 · Annealed SAE-AISI 4140 is SAE-AISI 4140 steel in the annealed condition. It has the highest ductility compared to the other variants of SAE-AISI 4140 steel. The graph bars on the material properties cards below compare annealed SAE-AISI 4140 to:SAE-AISI wrought steels (top), all iron alloys (middle), and the entire database (bottom).
AISI 4140 steel is categorized as low alloy steel which contains some significant levels of manganese, molybdenum, and chromium elements. This metal is applicable in a wide range of industries thanks to its physical and structural toughness. What does the number 4140 mean in this type of steel metal?
