Web5 Feb 2024 · 02-05-2024, 10:36 AM. I am assuming that when you say heat treated 4140 you are referring to 4140 pre hardened. Commonly available 4140 pre hardened is around Rockwell C 28-30 and intended to be machined fairly easily as is. I recently turned some of it just recently and it was no problem and gave a outstanding finish, far far better than 1018. All common arc welding processes, such as (SAW, SMAW, FCAW, GMAW, GTAW) can be used to weld 4140 alloy steel, but in order to prevent cracking, it must be preheated to 170-350 °C (350-650 °F) before welding, preheating interpass temperature depends on the section thickness of the steel. See more SAE 4140 (AISI 4140 steel)is a Cr-Mo series (Chrome molybdenum series) low alloy steel, the material has high strength and hardenability, … See more AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel plate, steel tube, and has many uses in the aerospace, oil … See more Below are 4140 alloy steel datasheets including chemical composition, properties and equivalent chart, etc. See more Web10 Apr 2024 · The AISI 4140 steel is recommended to preheat: Up to ½ inch (12 mm) thickness: 400- 500℉ (200- 250℃ approx.) Above ½ inch (25 mm) thickness: 500- 600℉ (250- 300℃ approx.) The above preheat temperature is based on the recommendation given in Welding handbooks such as ASM and AWS. alloggio re di roma
