Inconel Axles

As you rightly identified the material is chosen to avoid corrosion (and partly the erosion) becuase of the exposure of the vehicle bottom exposed to.

Inconel is a very common material in process industries.

Are there weight savings whilst achieving same strength??

In this application, a weight savings doesn't make a large difference in performance. Flex in the axle is the most important aspect. That being said, it never hurts to lower the rotating weight.

Inconnel is nickel based alloy and has different alloy combinations to suit the applications. some are ni-cu, ni -cr, ni-cr-mo. ni-fe-cr, ni-cr- al- ti etc.,

Aprat from its resistance to corrosion , they have good mechanical strength, chemical resistance at high temparature,high toughness and ductility at low and high temparature.

Hence the use of it for as pipes to avoid sea water corrosion as well as in automobile sector.

INCONEL® INCOLOY® MONEL® NILO® NIMONIC® UDIMET® are special alloys to withstand heat, corrosion, erosion, abrasion, wear, and retain high strength and resistance to oxidation at high temperatures.

MONEL is a nickel-copper alloy. The two types of monel are 400, and K-500. Monel alloy 400 has approximately 2/3 nickel and 1/3 copper. Monel alloy K-500 is similar, except that it has 3 % aluminum. Monel 400 has exceptional qualtities of strength, versatility, and resistance to heat and corrosion. K-500 is heat treatable, and is, in effect, a high strength version of the 400 alloy.

INCONEL is a nickel-chromium alloy. Alloy 600 contains about 76% nickel, 16% chromium, and 7% iron. This alloy is an outstanding material for applications where fastenings must retain high strength and resistance to oxidation at high temperatures ranging up to 1600 degrees.
