Abstract

The present invention relates to a martensitic stainless steel as used in tableware, knives, scissors and the like, which contains, as percentages by weight, from 0.10 to 0.50% of carbon and from 11 to 16% of chromium, and relates to a production method therefor; and the invention relates to a production method for mid-carbon martensitic stainless steel in a strip-casting device comprising a pair of rollers which rotate in opposite directions, an edge dam which is provided so as to form a molten steel pool at both side surfaces, and a meniscus shield for supplying inert nitrogen gas to the upper surface of the molten steel pool, wherein steel for stainless steel containing, as percentages by weight, from 1.10 to 0.50% of carbon and from 11 to 16% of chromium is supplied from a tundish, via a nozzle to the molten steel pool in such a way that a stainless-steel thin sheet is cast, and the cast stainless-steel thin sheet is made into hot-rolled annealed strips using in-line rollers to a rolling reduction of from 5 to 40%, and relates to martensitic stainless steel produced by means of the production method. The present invention suppresses lamination defects by reducing carbide centre segregation and makes it possible to obtain martensitic stainless steel with little difference in hardness between carbide-segregated zones and non-segregated zones and hence with uniform hardness overall.
