Title:
HIGH PROOF STRESS AND HIGH CORROSION RESISTANT AUSTENITIC STAINLESS CAST STEEL
Document Type and Number:
Japanese Patent JPH0770700
Kind Code:
A
Abstract:
PURPOSE: To provide high proof stress and high corrosion resistant austenitic stainless cast steel in which strength at a high temp. is close to double of that of SCS13 and SCS14, deterioration in toughness hardly occurs and corrosion resistance is equal to that of WCS13 and SCS14 as well.
CONSTITUTION: This steel has a componental compsn. contg., by weight, ≤0.1% C, ≤2.0% Si, 4.0 to 15.0% Mn, 4.0 to 10.0% Ni, 15.0 to 23.0% Cr, 0.2 to 4.0% Mo and 0.1 to 0.4% N, and the balance substantially Fe. This alloy may furthermore contain one or ≥ two kinds among ≤3.0% Cu, ≤3.0% W, ≤3.0% Co, ≤2.0% Nb and ≤0.5% Ti.
