EN 1.4558 (X2NiCrAlTi32-20) Stainless Steel Tube Sch80S intended for pipelines
Introduction to products:
EN 1.4558 stainless steel is a superaustenitic (highly alloyed)
stainless steel formulated for primary forming into wrought
products. Cited properties are appropriate for the solution
annealed (AT) condition. 1.4558 is the EN numeric designation for
this material. X2NiCrAlTi32-20 is the EN chemical designation.
It has a very low tensile strength among wrought superaustenitic
stainless steels. In addition, it has a moderately low base cost
and a moderately low embodied energy.
APPLICATIONS :
The 1.4558 grade is used in the chemical industry equipment
manufacturing nitric acid and derivatives, salts and fertilizers.
Also used in cryotechnics, in the pharmaceutical industry, in the
food industry - in food processing plants, dairies, sugar
factories, breweries, in the fuel industry, i.e. in refineries and
petrochemical plants.
Steel intended for pipelines, autoclaves, transport tanks, heat
exchangers, absorption towers, pumps, coolers, and reactors.
