Duplex Steel S31803 / S32205 Angle, Channel

The steel has great resistance to chloride stress oxidation crevice, low coefficient of thermal expansion, and high thermal conductivity. The higher levels of nitrogen, molybdenum, chromium offers great resistance to general oxidation, crevice, and pitting. There are various kinds of duplex steel angle & channel are available such as Duplex 2205 U Channel, SAF 2205 Lifting Chain, Duplex Steel S32205 C Shape Channel, High-Quality S31803 Duplex Steel H Beam, Duplex 2205 Equal Leg Angle, and many more.

Features of Duplex S32205/S31803 Angle/Channel
Grade 2205 is duplex stainless steel with equivalent extents of austenitic and ferrite steel.

These microstructures make it more resistant to stress oxidation crevice than grade 304 and 316L stainless steel. Grade 2205 contains high nitrogen, molybdenum, and chromium that increased crevice and pitting oxidation resistance in the existence of chlorides. The Duplex S32205/S31803 has yield strength that is twice compare to austenitic stainless steel. It is very appropriate for use in chlorides and hydrogen sulfide environments such as marine applications.

Corrosion resistance-
Because of its high nitrogen, molybdenum, and chromium content, grade 2205 determines excellent oxidation resistance properties compare to 316L and 316 in most environments. These contents also offer crevice corrosion and pitting even in an acidic and oxidizing atmosphere. The toughness of chloride stress oxidation crevice and temperature up to 150 degrees C (302 degrees F). It also contains the ferrite which offers the great performance of duplex 2205 grade in corrosive environments.

Heat resistance-
Like to another duplex stainless steel, this duplex 2205 grade is offering excellent corrosion resistance at high temperature. The substance to embrittlement for short time period, grade 2205 is hence not suggested for use above 300 degrees C (572 degrees F).

Welding characteristics-
Duplex S32205/S31803 Angle/Channel should not usually weld without filler metal as this might affect in extreme ferrite. Its process of weldability is good.
