Kind Code:
B2
Abstract:
A martensitic stainless steel for use in tableware, knives, scissors and the like, containing in % by weight, 0.10 to 0.50% carbon and 11 to 16% chromium, and a production method therefore. A production method for mid-carbon martensitic stainless steel in a strip-casting device comprising a pair of rolls rotating in opposite directions, edge dams respectively provided to both sides of the rolls so as to form a molten steel pool, and a meniscus shield for supplying inert nitrogen gas to the upper surface of the molten steel pool, wherein a stainless-steel thin sheet is produced by supplying a molten stainless steel of the above composition to the molten steel pool via a nozzle from a tundish, and a hot-rolled annealed strip is produced to a rolling reduction of 5 to 40% using in-line rollers, and relates to martensitic stainless steel produced by the production method
