High-strength, notch-ductile precipitation-hardening stainless steel

Free-machining austenitic stainless steel

An age hardenable nickel base chromium, molybdenum, alloy as well as intermediate products and articles made therefrom are disclosed which, in the solution treated and age hardened condition, have a 0.2% yield strength greater than 100 ksi combined with resistance to pitting and crevice corrosion and to stress corrosion cracking in chloride and sulfide environments at elevated temperatures up to about 500.degree. F. without requiring working below the recrystallization temperature of the alloy. Broad and preferred ranges are disclosed as follows:

Corrosion resistant age hardenable nickel-base alloy

An austenitic, stainless steel alloy having a unique combination of machinability and a low magnetic permeability, especially in the cold worked condition, is disclosed consisting essentially of, in weight percent, about

A process for making a clad article of a densified metal powder core and a compatible metal cladding metallurgically bonded thereto results in a significantly reduced concentration of metal oxides in the core so as to prevent embrittlement of the core at and adjacent the core/cladding interface that results in rupture between the core and the cladding along the interface during working or forming. In carrying out the process, the temperature of the undensified metal powder and/or the temperature of the compatible metal container into which the metal powder is filled are closely controlled so as to avoid adsorption of moisture during the filling step.

Process for making clad articles and article made thereby

A workable, boron-containing, stainless steel alloy and an article formed therefrom are disclosed together with a process for manufacturing same. The alloy consists essentially of, in weight percent, about

Workable boron-containing stainless steel alloy article, a mechanically

A stainless duplex ferritic-austenitic steel with improved corrosion resistance. The steel consists essentially of about: 0.03 w/o Max. carbon, 3.0 w/o Max. manganese, 1.0 w/o Max. silicon, 26.0 to 29.0 w/o chromium, 3.5 to 5.2 w/o nickel, 3.5 w/o Max. molybdenum, 0.15 w/o Min. nitrogen and the balance essentially iron. The steel preferably contains about 0.17 to 0.35 w/o nitrogen for improved pitting resistance and for increased austenite content. Welds of the steel preferably contain at least about 17% austenite in the as-welded condition for improved pitting and intergranular corrosion resistance.
