A ferritic stainless steel alloy is disclosed having a unique combination of machinability, cold-formability, weldability, and corrosion resistance. The disclosed alloy has the following weight percent composition. ______________________________________ wt. % ______________________________________ Carbon 0.08 max. Manganese 1.00 max. Silicon 1.00 max. Phosphorus 0.045 max. Sulfur 0.030-0.30 Chromium 10.5-11.75 Molybdenum 0.50 max. Copper 0.50 max. Nickel 0.50 max. Aluminum 0.10 max. Columbium 10 .times. C to 0.80 ______________________________________ The balance is essentially iron. The novel alloy is particularly suited for components used in automotive fuel and exhaust systems. A number of such components made from the aforesaid alloy are also disclosed.
A ferritic stainless steel alloy having a unique combination of cold-formability and machinability, said alloy consisting essentially of, in weight percent, about:
An article of manufacture comprising a metallic body having an axial bore formed therein and a plurality of threads formed on said metallic body whereby said metallic body can be threaded onto a second article having a mating thread, said metallic body being formed of a corrosion resistant, ferritic steel alloy having the following weight percent composition:
