S32707 1.4658 Duplex Stainless Steel

UNS S32707 is a hyper-duplex stainless steel, a high-alloy duplex steel with a PRE value of min. 48*. The grade is characterized by excellent chloride corrosion resistance, combined with very high mechanical strength.

S32707 is particularly suited for use in aggressive environments such as hot chlorinated seawater and for highly acidic, chloride containing media. S32707 has better resistance to pitting and crevice corrosion and higher mechanical strength than all super-duplex stainless steel grades available on the market.

Stainless Seamless Fluid Pipe Quality Control

  1. Raw materials pipe blank quality classification: high quality, medium, economical
  2. Raw materials inspection after receive in factory
  3. After pickled, tube will be grinded careful to less defect
  4. Multiple cold drawn/rolled process for precision dimension
  5. Standard heat-treated of continuous annealed/solution for better property, intergranular corrosion
  6. Full Inspection: ET, UT, Hydraulic Test, Penetration Test, Grinded, Sand Blast, Print Making

General corrosion

General corrosion can limit the service life of a stainless steel component in contact with a process solution. S32707 is highly resistant to corrosion by organic acids,e.g.formic acid and acetic acid.It also remains resistant in contaminated acid.The alloy is,therefore,a competitive alternative to high alloyed austenitic stainless steels and Ni-base alloys in applications where standard austenitic stainless steels corrode at a high rate.

Stress corrosion cracking

Stress corrosion cracking (SCC) is perhaps the most serious form of corrosion encountered in industrial processes as it can lead to rapid material failure.Standard austenitic grades can crack even at very low chloride levels.The risk of SCC can be eliminated with the use of more resistant

materials,such as high nickel alloys or duplex stainless steels.While the austenitic steels in many cases become resistant at Ni levels above 25%,the duplex alloys will have the same or higher resistance at much lower alloying levels,due to the dual phase structure .The SCC resistance of S32707 in chloride solutions at high temperatures is illustrated.An autoclave SCC test,where the samples are loaded to the yield strength R level,was conducted.The pressure was approximately 100 bar and the oxygen content 8 ppm.Fresh NaCl solution was pumped constantly into the chamber and duration of the test was 1000h (6 weeks).There were no signs of SCC up to 1000 ppm CI /300 C and 10000 ppm CI /250C.

Localized corrosion

In chloride containing waters under oxidizing conditions, pitting or crevice corrosion are perhaps the most common failure modes for stainless steels.Modern duplex stainless steels,such as 2507,were developed explicitly to have high resistance to pitting and crevice corrosion. All the experience gained from this grade has been utilized
