| 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 ma x. wt.%, Manganese 1.00 max. wt.%, Silicon 1.00 max. wt.%, Phosphorus 0.045 max . wt.%, Sulfur 0.030-0.30 wt.%, Chromium 10.5-11.75 wt.%, Molybdenum 0.50 max. wt.%, Copper 0.50 max. wt.%, Nickel 0.50 max. wt.%, Aluminum 0.10 max. wt.%, Columbium 10 x C to 0.80 wt.%. 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 a re also disclosed.
