Rustfrit Rundt Skaldrejet EN 1.4305

Grade 1.4305 is a free-machining stainless steel. In common with other austenitic grades like 1.4301 and 1.4307, it contains about 18% chromium and 9% nickel but the steel is also alloyed with sulphur for improved machinability. In general, stainless steels are regarded as more troublesome to machine than carbon steel but in 1.4305, the sulphur addition improves machinability to a degree that it is not so far removed from that for a free-machining carbon-manganese steel.

In comparison with 1.4301 and 1.4307, the sulphur addition to 1.4305 results in somewhat impaired corrosion resistance. However, the steel withstands atmospheric corrosion rather well at the same time as it is reasonably resistant to attack by rain water and less aggressive chemicals.
