Readily formed and welded,used mainly in domestic, dairy and decorative appliances general purpose grade for corrosion resistant applications.
This grade is the most widely used of all stainless steels. Its chemical composition,provide the best all-round performance S. It has excellent low temperature properties.
Lower Carbon grades S15 and less have improved weldability. It offers high resistance to corrosion. Generally machined components and pipe fittings. This grade is almost as popular as the grade the increased M o content makes the steel more suitable for resisting pitting and crevice then Grade.
Grade Titanium stabilized, which offers improved welding properties. Pocesses good resistance to scaling at high temperatures. For continuous high temperature service in the range oC. The values below are not comprehensive and must be used with extreme care.
