Slick Zeron

Very high strength and excellent corrosion resistance makes this a world class, first class product

slick zeronIs a super duplex stainless steel available in all wire diameters that has high mechanical properties whilst retaining good ductility. The alloy has excellent resistance to chloride and sulfide stress corrosion cracking, acid corrosion and crevice corrosion, making it suitable for use in many environments. Due to its high strength, ZERON®100 also exhibits excellent resistance to abrasion and high resistance to fatigue and corrosion fatigue. ZERON®100 has a low coefficient of thermal expansion that is similar to ferritic steels. Further information on any of these properties, or advice on the use of ZERON®100 is available on request.

CORROSION

In addition to excellent mechanical properties ZERON®100 Very High Strength (VHX) wirelines have exceptional corrosion resistance.

In sweet wells, ZERON®100 VHX wirelines are very resistant to corrosion by CO2, irrespective of chloride levels, up to high temperature (> 200°C). In sour wells, the main concern is failure by sulfide stress corrosion cracking (SSCC). ZERON® 100VHX wireline has been demonstrated to resist cracking in sour, condensed waters with 0.4 bar partial pressure of H2S. Produced waters have a higher pH, but also higher chloride content; and ZERON®100VHX wireline resisted cracking in 0.4 bar partial pressure of H2S. It therefore has applications in many sour wells.

The performance of ZERON®100VHX is similar to that of 6% Mo austenitic alloys at around 100°C, but it is superior at elevated temperatures, where the 6% Mo austenitic alloys are restricted to low chloride concentrations with high H2S levels by NACE MR0175/ ISO 15156.

Another important consideration for wireline users in marine atmospheres is atmospheric corrosion during storage as some of the failures of wireline in service are due to corrosion that has occurred during storage between uses. This corrosion acts as a local stress raiser that can lead to wire fracture in use. ZERON®100 VHX has exceptional resistance to corrosion in storage, even when tight crevices occur, so preventing premature failure.
