Ferritic & Martensitic Stainless Steel

Ferritic and martensitic stainless steel heat transferring tubing is produced to applications where better mechanical properties, hardness, chloride induced pitting, crevice and stress corrosion cracking may be considered. And the high quality tube and pipe with such material can be also used for other specific applications as petro/gas industry, bearing machining …Typical Grade: 410/S,430,439,446,444,440C,L80/13Cr,17-4PH,1.4418,S41426…
