MEXICO CITY Lázaro
Cárdenas SA de CV, ArcelorMittal SAs Mexican slab
and flat steel subsidiary, has recently started producing slabs
that will be used in pipelines transporting sour gas.
Such natural gas contains
"significant quantities of toxic gases, such as hydrogen
sulfide, carbon dioxide or similar contaminants," the company
The steel slabs must present
very stringent technical specifications, including a high
resistance against hydrogen-induced cracking (HIC).
"For this reason, best
technological practices were implemented at Lázaro
Cárdenas for the site to be able to produce defect-free
slabs with a reduced center segregation rate in order to
increase its share of the growing market for API (American
Petroleum Institute) pipes," the company said.
After undergoing several tests,
ArcelorMittal Mexico met all the requirements of its customers
in this project, Indian tube manufacturer Welspun Corp. and
Mexican coil plate producer Ternium SA, it said.
