Full-supply risers destined for North Sea
For a recently completed project for full-supply risers completed for Aquaterra Energy, the ends of the flanges were inlaid with an extremely hard, corrosion resistant Inconel 625 alloy. Now in place offshore, the risers are proving to be working reliably in the North Sea

Back on track: nuclear power emerges from its post-Fukushima blues
For a while, the earthquake-induced nuclear accidents in Japan in 2011 put a dent on the development of nuclear power. However, following a period when several countries carried out reassessments and national safety reviews, output has increased and delayed projects are being resumed. Research is flourishing and many technologies are being developed to make nuclear power safer. Good news for suppliers of special materials and equipment.

The last defence against corrosion: Alloy 945 & 945X
Incoloy® Alloy 945 and 945X are relatively new alloys in the pantheon of nickel alloy materials available in the market. This incredibly strong, age-hardenable nickel-iron-chromium alloy is the latest defence in the battle against corrosion.

Materials challenges in oil & gas exploitation 
National Oilwell Varco (NOV) is a vast organisation covering almost every aspect of oil and gas drilling and production activities onshore and offshore for both surface and subsea activities. With more than 60,000 employees in 69 countries, NOV has a wealth of knowledge and experience in the field of specifying and using stainless steel and other corrosion resistant alloys. Stainless Steel World spoke to two members of the NOV Completion and Production Solutions team to learn about the impact of low oil prices on business and some of the challenges that must be overcome through material selection in this demanding application.

50 year evaluation of St. Louis’ Gateway Arch
Stainless steel’s corrosion resistance made it a natural choice to achieve the desired longevity and aesthetic requirements to the exterior of the Gateway Arch in St. Louis, USA. While celebrated for its elegant symbolism and amazing size, many people do not realize that it was also visionary and innovative as the world’s first large structural application for stainless steel.

Duplex families and applications: a review
Part 1: From Duplex Pioneers up to 1991
This two-part article by Jacques Charles summarizes a review paper devoted to the key developments and main applications of duplex stainless steels presented at Duplex World Seminar & Summit 2014. Part 1 looks at the early ages and developments up to 1991.

ACHEMA ends on a high note
ACHEMA 2015, held 15 – 19 June, welcomed over 166,000 participants and a record number of exhibitors from the chemical, pharma and food industries.

Maximizing belt life performance & production in powdered metal sintering operations
Woven wire mesh belts are an ongoing cost associated with the operation of a continuous powdered metal sintering furnace. The life of a T314 stainless steel belt operating in one of these units is typically measured in months. A pretreatment to extend the belt life had been developed and tested and initial results have demonstrated a 25% increase in belt life and reduction in downtime.

TIG welding proves productivity
Following the success of its welding Symposium two months earlier, Polysoude hosted Open Days on 23rd and 25th June. With over 200 attendees, workshops and demonstrations highlighted the surprising scale of TIG applications for welding, cladding and buttering.
