What is the equivalent of 4130 steel?

What is the equivalent of 4130 steel?

AISI 4140
AISI 4130 steel is commonly referred to as Chromoly steel or chrome moly steel. It resembles the AISI 4140 (1.7225 / 42CrMo4) but has a lower carbon content (0.28-0.33%), giving the 4130 material improved weldability.

What does the designation of SAE 4130 mean?

4130 is a designation for a steel alloy that contains chromium and molybdenum among other elements. The exact composition range is defined in the standard SAE J404 [affil. link to spec at Techstreet] “Chemical Compositions of SAE Alloy Steels”.

Can 4130 be hardened?

AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment.

How hard can you heat treat 4130?

approximately 48 HRC
4130 is a medium-carbon (nominal 0.30%C) chromium-molybdenum alloy steel. Due to its carbon content, it is most often water quenched to attain a maximum as-quenched hardness of approximately 48 HRC.

What material is SAE 4140?

chromium molybdenum alloy steel
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.

Can 4130 be welded?

For instance, the approximate strength for annealed 4130 steel is 90 ksi, while the material in a normalized condition is around 100 ksi; quenched and tempered 4130 steel is stronger, offering strength up to 200 ksi. In addition, several types of filler metals can be used to successfully weld 4130 steel.

Do you need to heat treat 4130 after welding?

basically speaking 4130 has a high carbon content therefore the need for heat treatment is much higher than mild steel. it would be best to pre heat the material to prevent as much shrinkage and warpage as possible during the cooling process, then post weld heat treat the whole part.

Is 4130 easy to weld?

As one of the most common of the heat-treatable low-alloy steels, 4130 steel can be found in a number of industries and applications. It is also among the most likely to cause confusion when it comes to welding. Its high hardenability is the key to 4130 steel responding to heat treating.

Does 4130 need to be heat-treated?

Because of its high hardenability, 4130 steel responds well to heat treating, which offers advantages for many applications. But, this material can also vary in mechanical properties as a result, making it challenging to select a filler metal that matches its strength in a given condition.
