Product Description

High Elasticity Martensite Stainless Steel Maraging300 Rod Forging Cold Wire

 

Introduction

Maraging 300 is a 18% nickel, cobalt strengthened steel (C-type), with excellent mechanical properties, workability and heat treatment characteristics. It is also called 18Ni300.

 

Applications

Typical applications for maraging include missile and rocket motor cases, landing and takeoff gear, munitions, aerospace, extrusion tooling, die casting, high performance shafting, gears and fasteners.
