Nickel: production, use, exports and imports
By David Sear | 27 January 2020
Nickel is a hot topic at the moment because the next generation of batteries for electric vehicles is likely to have a higher nickel and lower cobalt content. This is good news in that the supply of cobalt is rather price inelastic but the plentiful supply of nickel oxide ore means this is not an issue for nickel. WBMS’s Peter Cranfield digs into the data.

China: imports of key raw materials for stainless
By David Sear | 15 October 2019
The World Bureau of Metals Statistics (WBMS) has just published China trade for the first half of 2019. In this edition of stats corner we are looking at the results for two of the most important raw materials for stainless – chrome and nickel. It is traditional for the chrome industry to talk in volume terms of gross weight for ore and ferroalloy. So we adhere to that and the stats are gross weight.

Sandvik has opened a state-of-the-art coiled tubing line for premium grades of seamless stainless steel products in smaller dimensions at its Zhenjiang tube mill near Shanghai, China. The commitment to produce longer lengths of weld-free coiled tubing locally will enable customers in the Asia Pacific region to receive deliveries within 28 days, instead of waiting four to six months for longer length reels to arrive from abroad.
Transition to renewables doesn’t rule out interest in offshore O&G
By David Sear | 17 September 2019
Renewed urgency over global warming, combined with faster than expected growth in the renewable energy sector, is forcing the oil and gas giants to rethink their goals and strategy. This transition is far from easy, and for the time being, most companies remain very active in on- and - especially - offshore exploration and exploitation, as James Chater reveals in this abridged article.

Indonesia: production and export leap in 2018
By David Sear | 30 April 2019
The World Bureau of Metal Statistics (WBMS) now has extensive 2018 trade data for stainless steel. In that year WBMS estimates that Indonesia produced 2.2 Mt of stainless slabs or 4% of global production. Compared to 0.6 Mt in 2017 this represents a near four-times increase: an important consideration as production is expected to continue to increase strongly. And as mentioned in a previous ‘stats corner’, production in Indonesia tends to be ‘low cost’.
How stainless supports communications
By David Sear | 15 April 2019

Molybdenum-containing stainless steel lashing wire is used particularly in coastal areas to avoid premature corrosion failure of this essential support structure…
No 1 AOD converter start-up at Outokumpu Tornio works
By David Sear | 08 April 2019
The project involved fitting the converter with a new tilting drive, trunnion ring and other associated equipment, including the electrical installations and automation. The Vaicon Drive Damper system developed by Primetals Technologies was also installed on the tilting drive. It reduces the vibrations produced by the blowing processes and thus the mechanical loads acting on the entire system from the converter down to the foundations. The patented system reduces wear and maintenance costs while
Scrap is a valuable raw material for stainless
By David Sear | 11 March 2019
It is said that virtually all the gold ever produced is still in existence. It is a valuable metal that does not degrade. The same should be said of stainless. It is a valuable resource that does not degrade with time. Of course some does go to landfill, but more is being recovered at end of life and long may this continue.

‘HFree’ - Hydrofluoric acid free pickling
By Roy van IJzendoorn | 26 September 2017
A new pickling process which does not require the use of hydrofluoric acid has been developed as part of a project funded by the EU through the LIFE programme (project code: 13 ENV/IT/000440). The process is beneficial in terms of both the environment and energy consumption. This article analyses the characteristics of the wastewater treatment process deriving from the new pickling process which eliminates once and for all the presence of hydrofluoric acid in the base solution.
