A lot has happened since the Nippon Steel Corporation and Sumitomo Metal Industries, Ltd. merged to form the Nippon Steel & Sumitomo Metal Corporation (NSSMC) in October 2012. The integration of the two companies not only led to the formation of a world-leading integrated steel producer but also safeguarded it as a world leader in the market of special tubes. Stainless Steel World recently revisited the company to talk about the impact of the integration, the advantages it has brought and is bringing, as well as continuing company ambitions with Mr. Tomohiko Ogura, Head of Division, Specialty Tubular Products Marketing Division, Pipe and Tube Unit; Mr. Takeo Watanabe, Head of Department, Chemical & Shipbuilding Tubular Products Marketing Department, Pipe and Tube Unit; and Mr. Satoshi Matsumoto, Head of Department, Specification & Quality Control Department, Quality Control & Technical Service Division, Amagasaki Works.
Aerospace and power generation drive nickel market
In early 2014, Indonesia’s export ban was expected to lead to a supply squeeze. However, the sluggish economy and deflationary forces put paid to this. But the aerospace and power generation sectors are performing better than the economy as a whole, and nickel alloys are crucial for their future development. Alloys originally developed for aircraft construction are spreading to other sectors, such as auto and oil and gas. Meanwhile 3D printing is boosting the use of Ni alloys.
Duplex Stainless Steels – a happy marriage between austenite and ferrite
Jan-Olof Nilsson worked for Sandvik for over 35 years as a materials expert and was Adjunct Professor of Physics at Chalmers University of Technology for 9 years. He is now an independent consultant specialized in duplex. In this article, Mr Nilsson looks at how the 2 building blocks of duplex work together to give the alloy its properties.
Value for money. Edwin Prinse gives an insider’s view on procurement
A properly structured procurement strategy is a key element for success in any industry, but especially in oil and gas. It requires flexibility, reliability, accuracy and common sense, to name just a few characteristics of a procurement professional. Procurement has grown to become a specific task for dedicated officials and department. Mr Prinse is one such professional who, despite his busy schedule as Procurement Manager at Iv-Oil & Gas, he found some space in his agenda to talk to Stainless Steel World about his work.
Laser creates super-hydrophobic metals
Scientists at the University of Rochester in the US have used lasers to transform metals – including stainless steel – into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings. These super-hydrophobic properties could lead to applications in solar panels, sanitation and in anti-icing applications. Stainless Steel World contacted Professor Guo to find out more.
Corrosion resistance of copper bearing Ni Alloy (UNS N06845) for chemical plants
Stainless steels and nickel alloys are widely used in chemical plants for equipment in contact with very corrosive solutions such as sulfuric and hydrochloric acids. As molybdenum and nickel are beneficial to improving corrosion resistance, high Mo containing Ni alloys have been successfully used, although these do increase material costs. Researchers have found that copper, which is less expensive, can also improve corrosion resistance.
MTI members exchange knowledge at EuroTAC
The MTI is a global network of materials specialists founded in 1977. Its mission is to maximize member asset performance in a number of ways, for example by providing additional education opportunities for professionals in materials technology and by sponsoring research and development. Another valuable objective is to provide networking opportunities, like the EuroTAC Spring 2015 meeting that recently took place in Aachen, Germany.
Rising by fits and starts: India’s stainless steel market remains strong
After a period of high growth rates, the Indian economy has slowed. The country is still saddled with considerable obstacles to growth, yet it is still high compared with western countries, and several stainless steel suppliers are emerging on the global scene as if from nowhere. The country has several mature industries that consume large amounts of stainless steel: nuclear and coal power generation, petrochemical. Meanwhile other sectors such as water treatment, architecture and transport, can be expected to grow rapidly in the future.
Properties of HIPed Hyper Duplex Stainless Steel
Duplex stainless steels have a matrix consisting of approximately 50/50 austenite and ferrite. These alloys are known for their good corrosion resistance combined with a high mechanical strength within a service temperature of -50°C to 250°C. At lower temperatures, the ferrite becomes brittle due to the ductile to brittle transition and at higher temperatures it becomes brittle due to spinodal decomposition. But what happens at even higher temperatures?
Stainless Steel World 2015 Conference taking shape
With only seven months to go before this year’s Stainless Steel World Conference & Expo takes place in Maastricht, things are beginning to hot up with regard to preparation of the conference for the event. The Steering Committee recently came together to select paper presentations and discuss workshops and plenary lectures. We bring you an update on our preparations and reasons why you should be there.
The 3D evolution: from prototyping to mainstream manufacturing
Held in Berlin on 3rd and 4th March, 2015, the Inside 3D Printing Conference and Expo attracted around 1,000 professional visitors from 46 countries, eager to learn if and how so-called 3D techniques could benefit their own businesses. Equally curious about this emerging technology Stainless Steel World also travelled to Berlin, to see if 3D prints can be made using corrosion resistant alloys.
