| 摘要 |
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: Carbon 0.08 max. wt.percent, Manganese 1.00 max. wt.percent, Silicon 1.00 max. wt.percent, Phosphorus 0.045 max. wt.percent, Sulfur 0.030-0.30 wt.percent, Chromium 10.5-11.75 wt.percent, Molybdenum 0.50 max. wt.percent, Copper 0.50 max. wt.percent, Nickel 0.50 max. wt.percent, Aluminum 0.10 max. wt.percent, Columbium 10 x C to 0.80 wt.percent. 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.
