Felkis The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with HT. Download Asmt statement concerning the use of stainless steels as food contact surfaces of equipment. Incoloy HT has further modifications to the combined titanium and aluminum levels. Humble, Texas fax Chemical and petrochemical processing industries use the alloys for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required.
