JIS G4305: 2005 / JIS G4304:2005 SUS890L stainless steel
JIS G4305 SUS 890L is a full martensitic stainless steel material. Compared with other high Mo element grades of martensitic stainless steel materials,JIS G4305 SUS 890L is not sensitive to the ferrite. The typical character of JIS G4305 SUS 890L is that, its C element is low to 0.02%. So after heat treatment and weldeding, no carbide is separated out.
JIS G4305 SUS 890L is mainly used for petroleum and petrochemical equipment, and storage devices of sulphuric acid, and so on. This material is not common used. So the MOQ to produce is about 100 tons.
