Abstract

PURPOSE: To obtain an alloy cast steel with superior high temp. strength and hardness for a piercer and a plug mill used in a Mannesmann seamless steel pipe manufacturing system by adding a specified amount of N to a high-Mn high-Cr low-Ni steel.
CONSTITUTION: An alloy cast steel having a composition of 0.25W0.45% C, 0.25W 2.0% Si, 8.0W18.0% Mn, 6.0W19.0% Cr, 0.1W7.0% Ni and 0.02W0.45% N is used as a material for a piercer and a plug mill used in the manufacture of a seamless steel pipe from a red-hot billet by a Mannesmann system. To the steel may be added Co, Mo, V, W, Nb, Ta, Zr, Cu, Al, etc. This steel has characteristics such as superior hardness and strength at a temp. as high as 1,200°C.
