Especificación, química y rendimiento mecánico
UNS N08367 - Super Austenitic Stainless Steel
UNS N08367 equivalent 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 Group supplies this product in plate, sheet, strip, bar, rod form.
Other form, kindly send us the artwork, we will produce basing on your request.
trabajabilidad
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.
soldabilidad
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.
maquinabilidad
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.
Tratamiento térmico
Because N08367 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:
- Tratamiento térmico en solución: 1125 ~ 1175 ℃; Refrigeración por agua
Decapado
Una mezcla de ácido nítrico y ácido fluorhídrico se utiliza en decapado. Sin embargo, debido a la alta resistencia a la corrosión de N08367, la incrustación es algo difícil de eliminar en comparación con el Tipo 304. Por lo tanto, el material debe sumergirse en una solución alcalina antes del decapado, o si es posible, el granallado es extremadamente efectivo.
Aplicaciones
- 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.
