UNS N08020
UNS N08020 is a stainless steel with extremely high corrosion resistance to sulfuric acid. It can be used in a wide range of sulfuric acid environments, including high concentration, high temperature environments. It possesses excellent intergranular corrosion resistance and stress corrosion cracking resistance.

작업 성
The hot workability and cold workability of UNS N08020 are basically the same as those of standard austenitic stainless steels.
용접성
TIG welding, MIG welding, and shielded metal arc welding are applicable in the same manner as with standard austenitic stainless steels. However, because N08020 is an Nb-added stainless steel, the welding heat input should be reduced as far as possible.
Use of ER320 or ER320LR welding electrodes is recommended.
가공성
The machinability of N08020 is basically the same as that of standard austenitic stainless steels. In machining, a high speed steel tool or ultrahard tool should be used. It is also advisable to use a slower feed rate and deeper cutting depth.
열 치료
Stabilizing heat treatment: 925~1010℃ (conditions provided in ASTM A480/A480M) and quenching.
산세
Pickling is performed under the same conditions as with Type 304, using a mixture acid of nitric acid and hydrofluoric acid.
