1.4529, UNS N08926 - Super Austenitic Stainless Steel
UNS N08926 equivalent, 1.4529, is a high corrosion resistant stainless steel with high contents of chromium and molybdenum, and provides excellent corrosion resistance under severe environments such as high temperature seawater and flue gas desulfurization plants. Depending on the environment, it is a highly economical stainless steel with corrosion resistance comparable to that of Nickel alloy and pure titanium. Shanghai Bozhong Steel supplies this product in plate, sheet, strip and pipe form.

작업 성
Cold and hot workability are approximately equal to those of Type 304, 316, and other standard austenitic stainless steels. However, care is necessary for both cold and hot worked materials because they have high strength.
용접성
Possible welding methods include shielded metal arc welding, TIG welding, and plasma welding, in the same manner as with standard austenitic stainless steels. As welding consumables, Alloy 276 should be used. Preheating and post-welding heat treatment are not necessary.
가공성
As a distinctive feature of high Ni stainless steels, machinability is difficult in comparison with the austenitic stainless steels, but is easier than with Ni-based alloys. Use of a superhard tool whenever possible, together with a slow feed speed and large cut depth, is advised.
열 치료
Because N08926 is an austenitic stainless steel, heat treatment also conforms to that of standard austenitic stainless steels. The heat treatment conditions normally used with this material are as follows:
- 용액 열처리 : 1125 ~ 1175 ℃; 수냉
산세
질산과 불산의 혼합물은 산세에 사용됩니다. 그러나 N08926의 높은 내 부식성으로 인해 304 유형에 비해 스케일을 제거하기가 다소 어렵습니다. 따라서, 산세 전에 재료를 알칼리 용액에 담 그거나 가능하면 샷 블라스팅이 매우 효과적입니다.

- Seawater environments: Seawater desalination equipment, heat exchangers using seawater, condenser tubes, etc.
- High concentration chlorine ion environments: Flue gas desulfurization systems, pulp and papermaking industries, various types of bleaching equipment, etc.
- High concentration salt-containing environments: Resin manufacturing equipment, chemical reactors and piping, etc.
