AISI ASTM A269 Tp Ss 304 304L 316 316L Stainless Seamless Steel Pipe/Welded Tube

Stainless Steel Pipe Pipeline API DIN EN ASTM Seamless Steel Tube Round Pip

• High resistance to pitting and crevice corrosion

• Excellent in most caustic environments

• Good weldability

To be considered Duplex 2205, a stainless steel must have a chemical composition that includes:

• Cr 21-23%

• Ni 4.5-6.5%

• Mn 2% Max

• Mo 2.5-3.5%

• N 0.08-0.20%

• P 0.30% max

• C 0.030% max

This unique mix of materials makes Duplex 2205 the right choice for a number of different critical applications in a range of industries, including:

• Chemical processing, transport, and storage

• Marine and Land cargo tanks

• Biofuel production

• Food processing

• Pulp and Paper manufacturing

• Oil and gas exploration and processing

• Waste management

• High chloride environments

• Surface Finish	Definition and Application
  No.1	The surface is finished by heat treatment and pickling or processes corresponding theretoafter hot rolling
  2D	The finishes after cold rolling, by heat treatment,  pickling or other equivalenttreatment
  2B	The finish after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to give an appropriate luster
  BA	Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror
  NO.3	Polished with abrasive belt of grit#100~#200,have better brightness with discontinuous coarse stria
  NO.4	Polished with abrasive belt of grit#150~#180,have better brightness with discontinuous coarse stria
  HL	Polished with abrasive belt of grit#150~#320 on the NO.4 finish and has continuous streaks
  8K	The product have excellent brightness and prefect reflexivity can be the mirror
