Ferritic-austenitic stainless steel |
摘要 |
A duplex stainless steel alloy has been provided which contains in % by weight: -C max. 0.05 -Si max. 0.8 -Mn 0.3-4 -Cr 28-35 -Ni 3-10 -Mo 1.0-4.0 -N 0.2-0.6 -Cu max. 1.0 -W max. 2.0 -S max 0.010 -Ce 0-0.2 the remainder being Fe and normally occurring impurities and additives. The ferrite content is 30-70% by volume, balance austenite. The steel alloy is very suitable in the environments that exist at the production of urea, in which it may advantageously replace the austenitic steels used so far.
