Rostfria Stålsorter
Våra Rostfria Kvaliteter
Här hittar du en enkel tabell för innehållet i dom mest förekommande stålsorterna samt jämförande beteckningar.
Dom flesta Stålverken använder interna benämningar vilket ibland kan kännas lite vilseledande.
Ferrit / Kromstål = Magnetisk mycket krom och lite nickel , känslig för korrosion och används oftast inomhus typ Storkök m.m.
Martensit = Ett Härdbart stål
Duplex = Ett känt begrepp för Rostfritt stål med högsträckgräs samt bra motstånd mot korrosion.
Austenitic = Dom mest vanliga stålsorterna på marknaden här finns 1.4301 ,1.4404 m.m.
Heat and Creep = Värmetåliga stål där den mest förekommande är 1.4835 / 253 MA en produkt från Outokumpu.
