  • UNS N08028/DIN W. NR. 1.4563 SEAMLESS PIPE

  • Huashang

  • 7507120000

Alloy 028 is a highly alloyed austenitic stainless steel providing resistance to both oxidizing and reducing acids and salts due to its contents of chromium and molybdenum.

And the presence of copper increases its resistance to sulfuric acid.


APPLICATIONS

Equipment handling reducing chemical environments and chemical process industry involving hydrochloric, sulfuric, phosphoric and acetic acids.


Our pipe factory has 296 employees ,including 4 senior engineers,18 engineers and 38 professional technicians.
