Sandvik Materials Technology will present its advanced corrosion resistant alloys including duplex, super-duplex and hyper-duplex stainless steels at the NACE Foundation’s CORROSION 2014 exhibition in San Antonio, Texas.

“NACE 2014 is an invaluable occasion for us to connect with industry professionals and demonstrate our ability to address critical corrosion resistance issues which lead to material failure, plant breakdowns and costly lost production time.
Our full portfolio of corrosion resistant alloys offer extreme resistance to corrosion caused by chlorides, aggressive chemicals and media in varied applications,” said Magnus Brodin, Sandvik Group Sales Development Manager Tube.

Sandvik material grades have demonstrably superior corrosion resistance in the kinds of harsh environments withstood by hydraulic and instrumentation as well as heat exchanger tubing, over standard steel grades like ASTM 316 and 316L
which have proved insufficient in such applications. Products displayed at CORROSION 2014 include umbilicals, hydraulic and instrumentation tubes, coiled workover tubing, composite tubes, finned tubes and thermocouples.

In industry corrosion tests, Sandvik SAF 2507TM proved to be one of the best materials for replacing 316L for hydraulic and instrumentation tubing in offshore platforms. The super-duplex stainless steel has very high resistance to pitting
and crevice corrosion, with excellent resistance to stress corrosion cracking in chloride bearing environments.

Sanicro™ 28, a high-alloy austenitic stainless steel for demanding conditions, exhibits superior resistance to pitting and crevice corrosion, while the nickel alloy Sanicro™ 41 provides improved resistance to acidic media such as sulphuric acid.

Magnus Brodin added: “Materials like Sandvik 3R60 Urea Grade, a high purity variant of ASTM 316L with a low ferrite content for greater resistance to general, intergranular and pitting and crevice corrosion, are crucial in helping our customers
achieve today’s cost efficiencies, higher output and reduced maintenance.”
