Maraging 300 is a promptly machined while in the tempered condition. Full properties accomplished through martensitic precipitation aging. Maraging 300 is a piece of the 18% Nickel Maraging Steel family close by Maraging 200 and Maraging 250. When working with Maraging steels despite the fact that some of them contain Ti (Titanium) and some contain Co (Cobalt) as their reinforcing combination, it's essential to recollect that their physical properties contrast just marginally and are quite similar.
The number in the grade name (300 for this situation) compares, generally, not 100% but rather much of the time, to the rigidity of that combination. Regularly outfitted in the toughened condition Maraging 300 can be anything but difficult to machine and relatively soft. However after warmth treating by means of a precipitation solidifying position the hardness increments enormously which makes this steel adequate for some tooling applications. Maraging Steel 300 is available in Round Bar. On the off chance that there's a Maraging item not recorded in the size or shape you require please call Michlin today.
