Abstract: Ferritic stainless steel consisting essentially of, in % by weight, 0.0050 to 0.0500 of C, 10.00 to 18.00 of Cr, up to 0.50 of Si, up to 0.50 of Mn, more than 0.040 but not more than 0.200 of P, up to 0.030 of S, up to 0.60 of Ni, 0.005 to 0.200 of Sol. Al, and 0.0020 to 0.0050 of B, the balance being Fe and impurities, and having a longitudinal cracking transition temperature of not higher than -10.degree. C. as determined by the cup expansion test hereinbefore described. The steel has excellent formability and secondary workability.

Abstract: A novel iron based alloy is disclosed which is characterized by high resistance to wear and corrosion. The alloy consists essentially of 0 to 40% chromium, 1 to 40% molybdenum, 1 to 15% copper, 0.2 to 5% boron, and 0.01 to 2% carbon; the balance being incidental impurities and at least 30% iron, with the molydenum being at least 10% if the boron is greater than 2%. The alloy is preferably in the form of a powder for thermal spraying, and coatings produced thereby may have an amorphous structure.

Abstract: A process for preparing an iron group sintered compact involves forming an admixture of an iron group metal alloy powder additive and iron powder wherein the melting point of the alloy additive is at least about 50.degree. C. lower than that of the iron, compacting the admixture to form a green compact, and sintering the green compact at a temperature of from about 20.degree. C. above the solidus to about 100.degree. C. above the liquidus of the alloy additive whereby a sintered compact is formed. A compact having an iron group alloy additive as a continuous phase and iron as a discontinuous phase wherein the continuous phase has a melting point of at least about 50.degree. C. lower than that of the discontinuous phase can be prepared at lower sintering temperatures than a typical iron powder.

Abstract: Manganese-iron base and manganese-chromium-iron base austenitic alloys designed to have resistance to neutron irradiation induced swelling and low activation have the following compositions (in weight percent): 20 to 40 Mn; up to about 15 Cr; about 0.4 to about 3.0 Si; an austenite stabilizing element selected from C and N, alone or in combination with each other, and in an amount effective to substantially stabilize the austenite phase, but less than about 0.7 C, and less than about 0.3 N; up to about 2.5 V; up to about 0.1 P; up to about 0.01 B; up to about 3.0 Al; up to about 0.5 Ni; up to about 2.0 W; up to about 1.0 Ti; up to about 1.0 Ta; and with the remainder of the alloy being essentially iron.
