4140 hollow pipe singapore Heat treatment

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 other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content. The higher carbon content of AISI 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy 4140 HIGH TENSILE STEEL - InterlloyHeat Treatment Annealing Heat to 800 oC - 850 C, hold until temperature is uniform throughout the section and cool in furnace.

Oct 15, 2019 · Oct 15, 2019 · Heat treatment is thermal cycling involving one or more reheating and cooling after forging the purpose of obtaining desired microstructure and mechanical properties in a forging. Few forgings of the types are produced without some form of heat treatment.Untreated forgings are usually relatively low carbon steel parts for noncritical applications or are parts intended for further hot mechanical work and subsequent heat treatmentHow is AISI 4140 alloy steel seamless pipe produced?Considered to be a mechanical tube, the aisi 4140 steel pipe is produced by either cold finishing or by means of hot finishing, which is usually cast in ingots or if required, strand cast. Once the pipe has been hot worked, it could be cold finished, and finally, they are coated with oil prior to being formed.See all results for this questionHow to heat treat 4140 - The Home Machinist!Mar 11, 2011 · Mar 20, 2011 · Re: How to heat treat 4140. Heat to 1500-1600° F and hold 1-1/2 hour per inch of greatest thickness. Quench into 150° F oil. Temper immediately after quenching, before the part has cooled to below 150° F. Parts should be held 1 hour per inch of thickness, 2 hours minimum. A single temper is sufficient.
