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 0-0.2the 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.
