1.What
is 18ni300

18ni300 is an ultra-high strength steel
based on non carbon (or micro carbon) martensite, which can produce
intermetallic compound precipitation hardening during aging. Different from
traditional high strength steel, it is strengthened by the dispersion of
intermetallic compounds instead of carbon. This makes it have some unique
properties: high strength and toughness, low hardening index, good formability,
simple heat treatment process, almost no deformation during aging, and good
weldability. Therefore, maraging steel has been widely used in the departments
that need this property.
