Duplex Steel Scrap
Duplex Steel Scrap comes under stainless steel category
but with some special charachtristics it is a second-generation, nitrogen-alloyed
duplex stainless steel (ferritic-austenitic). It offers an excellent
combination of both strength and corrosion resistance over a wide
range of applications. The approximate 50/50 ferrite-austenite structure
provides excellent chloride pitting and stress corrosion
cracking resistance, with roughly twice the yield strength of the
standard austenitic stainless grades.
The high chromium and molybdenum content, coupled with the nitrogen addition in 2205, provides general corrosion, pitting, and crevice corrosion resistance superior to Stainless Steel rades like 316L and 317L. Duplex steel demonstrates superior erosion-corrosion resistance when compared to 316 stainless steel. It is not subject to intergranular corrosion in the as-welded condition. Duplex Steel metals can be machined by conventional methods. Being widely used in Oil and Gas Industries, Pulp & Paper Industries, Power Generation, Construction Industries, Offshore Industries, Water destilation Industries etc..Some of the common or regular Duplex Steel grade Scrap are as following :-
Grades of Duplex Steel Scrap
There are few grades in Duplex Steel with minor difference in chemical composition or mechanical properties.
2205 (UNS S31803) Duplex Stainless Steel Scrap
2205 (UNS S32205) Duplex Stainless Steel Scrap
Type of Duplex Steel Scrap
Normally there are two basic categories in metal scrap and that is the same here with Duplex Stainless Steel Scrap i.e. Plate Cut Duplex Steel Scrap and Industrial Duplex Steel Scrap. For component casting founderiesDuplex Steel Plate Cut Scrap is in major demand where as Duplex Steel Industrial Scrap isbeing demanded in melting and con casting jobs.
