ABSTRACT:
Ferritic stainless steel having excellent machinability and local corrosion resistance comprises 21-30% chromium, less than 0.020% carbon, less than 0.050% nitrogen, 0.4-3.5% silicon, less than 3.0% manganese, 1.0-5.0% molybdenum, 0-3.0% vanadium, 0-5.0% nickel, and at least one element selected from the group consisting of 0.05-0.20% sulfur, 0.05-0.30% selenium, 0.05-0.30% tellurium, 0.01-0.20% lead, 0.01-0.20% bismuth and 0.005-0.065% calcium. When from 0.3-3.0% vandium is included the Si content should be 0.4-0.7%. When no vanadium is included the Si content should exceed 1% but not 3%.
