Duplex Stainless Steel Plate Supplier

Duplex stainless steels are called "duplex" because they have a two-phase microstructure consisting of ferrite and austenitic stainless steel grains. When a duplex stainless steel is melted, it solidifies from the liquid phase into a fully ferrite structure. When the material cools to room temperature, about half of the ferrite grains transform into austenite grains ("islands"). The result is a microstructure that is approximately 50% austenite and 50% ferrite.

Duplex stainless steels are approximately twice as strong as ordinary austenitic or ferritic stainless steels. As with all stainless steels, corrosion resistance is largely dependent on the composition of the stainless steel. For resistance to chloride pitting and crevice corrosion, its chromium, molybdenum and nitrogen content is most important. Duplex stainless steel grades have a range of corrosion resistance similar to that of austenitic stainless steels, i.e., from type 304 or 316 (e.g., LDX 2101©) to 6% molybdenum (e.g., SAF 2507©) stainless steels.

Hongguan Steel is an ISO 9001:2008 certified company and a leading stockist, supplier and exporter of ASTM A240 duplex stainless steel sheet.

Duplex Stainless Steel Plate Surface

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.
NO.2D Cold-rolled,   an nealed and pick led with out skinpassing the dull products can be used as   automobile parts, building materrials and pipings.
NO.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   discontinuous coarse stria, used as in ner and ex ter nal or na ments for   building, electrical appliances 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.
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 annealed and skin passed, the product has excellent brightness   and good reflexivity like mirror, used for lectrical appliances, mirror,   kitchen apparatus, or nament materials etc.
