2507
Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.
Surface Finished Of Stainless Steel Sheet :
Surface finish | Characteristics & Application |
NO 1 | Hot-rolled surface,annealed and pickled,can be used as cold-rolling material,industial tanks and chem i cal devices. |
2D | Cold-rolled, an nealed and pick led with out skinpassing the dull prod ucts can be used as auto mo bile parts, build ing materrials and pipings. |
2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surfacetreament to improve its mechamical properties, N02B could nearly satisfy comprehensive uses. |
NO.3 | Polished with abra sive belt of grit #100#120,have bet ter bright ness with dis con tin u ous coarsestria, used as in ner and ex ter nal or na ments for building, elec tri cal ap pli anc es and kitchen uten sils etc. |
NO.4 | Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3, are used as bathtud buildinginner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |
#320 | Polished with abrasive belt of grit #320, have better brightness with discontinuous coarse stria,but thinner NO.3, are used as bathtub building inner and external ornaments electrical appliances kitchen utensils and food lprocessing equipment etc. |
HL | Polished with abrasive belt of grit #150-320 on the No.4 finish and has continuous streaks,mainly used as building ornaments, elevators, door of building, frontal plate etc. |
BA | Cold rolled, bright an nealed and skin-passed, the prod uct has ex cel lent bright ness and good re flex iv i ty like mirror,used for lectrical appliances, mirror, kitch en apparatus, or na ment ma te ri als etc |
