Maraging 250 is an intense, moderately delicate and in this manner promptly machined and formed. Full properties accomplished through martensitic precipitation aging. Full Maraging 250 is a piece of the 18% Nickel Maraging Steel family close by Maraging 200 and Maraging 300. When mulling over Maraging steels, despite the fact that some of them contain Cobalt and some Titanium as their reinforcing compound, one must recall that their physical properties are similar.
So comparative are they that the number in the review name (250 for this situation) relates, moderately, not 100% but rather by and large, to the rigidity with most different properties the same. Generally outfitted in the strengthened condition Maraging 250 is moderately delicate and simple to machine. Anyway after warmth treating and by means of precipitation solidifying the hardness increments extraordinarily which makes this steel adequate for tooling applications. Maraging Steel 250 is available in Round Bar in AMS 6512 and MIL-S-46850.
