AISI 4140 Alloy Steel (UNS G41400) - AZoMAISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating it at 913°C (1675°F) for a long period of time, followed by air cooling.
AISI 4140 Pipe, 4140 Tube Stock, 4140 Tubing SupplierAISI 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.
The alloy steel pipe is specified by the AISI four digit number. They contain different types of steel, and their composition exceeds B, C, Mn, Mo, Ni, Si, Cr and Va limits set for carbon steel. AISI 4140 alloy steel is low alloy steel containing chromium, molybdenum and manganese.

AISI 4140 steel seamless pipe is an engineering alloy steel containing chromium and molybdenum. EN 19 pipes comes under the class of low alloy steel. EN 19 seamless pipe has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.
How To Weld 4140 Steel WELDING ANSWERSAISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a
SAE AISI 4140 Steel Properties, Material Heat Treatment Dec 14, 2019 · 4140 alloy steel is typically normalized at 870 °C (1600), and should be cooled at a specified temperature in still air. Spheroidizing Annealing For spheroidizing annealing of 4140 alloy steel, it needs heat treated to 749 °C (0 °F), followed by slowly cooling to 666 °C (1230 °F) at a rate of 6 °C (10 °F)/hour, or rapid cooling to 675 °C for isothermal annealing.
ScopeCharpy V Notch TestingReference DocumentsASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing. It is manufactured by hot working and then cold finishing the steel into round, square, rectangle or special shapes. AISI 4140 is a steel formula designation indicating medium carbon content with strengthening alloys that include chromium, manganese, silicon, molybdenum, sulfur and phosphorus.4140 Tube - AISI 4140 Steel Tubing - Seamless Alloy Steel Properties And Characteristics Of The 4140 Steel Pipe & Tube 4140 Steel Tubing Has Thicker Walls And Also Have The Good Resistance Which Make It More Compatible With The Industry Machineries And Pipeline Transmission Systems. And Also If We Compare It With Cold Drawn Products It Seems Much Better Than In Properties & Performance.
