Bankruptcy of China Bohai Steel Threatens Chain Reaction in Industry (US)

Bohai Steel is the third-largest state-owned steel enterprises to go bankrupt in the last two years. Dongbei Special Steel filed for bankruptcy in 2016 after Chairman Yang Hua committed suicide in March 2016. Chongqing Iron and Steel went bankrupt in July 2017.

With nearly $28 billion in unpaid debts, China Bohai Steel has begun to file for bankruptcy, in a process that will affect 48 factories and 105 creditors in Tianjin, a port city of 15 million people located near Beijing.  Bohai Steel’s bankruptcy process, which began in September, could have serious repercussions for the Tianjin financial sector, as it owes debts to seven major regional banks, including the Beijing Bank, Tianjin Bank, Tianjin Binhai Rural Continue reading

The U.S. Navy’s Naval Sea Systems Command (NAVSEA) has  approved the first metal part created by 3-D printing for shipboard installation. A prototype, 3-D printed-metal drain strainer orifice for a steam line will be installed on the carrier USS Harry S. Truman for a one-year test and evaluation trial. The DSO assembly is a steam system component that allows the drainage of water from a steam line while in use. Huntington Ingalls Industries – Newport News Shipbuilding (HII-NNS) proposed installing the prototype on an aircraft carrier for test and evaluation. “This install marks a significant advancement in the Navy’s ability to make parts on demand and Continue reading

Purdue University Raises $800,000 to develop high-performance propellant that uses an aluminum, lithium alloy for missile, space launch systems (US)

Static fire stand for a rocket test using a propellant called ALITEC that uses an aluminum, lithium alloy.   A test fire by Adranos Inc. of a high-performance, solid propellant for long-range missile and space launch systems. Adranos officials say the novel propellant has more thrust and is less corrosive than traditional solid propellants.  The propellant could be used by the Army, Navy, Air Force, NASA, and other Department of Defense agencies as well as U.S.-allied nations.

Titanium pipework at 100 bars for the UK’s first electric propulsion system for satellites (US)

 

The first electric satellite propulsion system to be entirely designed and built in the UK is in the final stages of manufacturing and should be shipped out before the end of the year. The Xenon Propulsion System (XPS) module is a key part of Thales Alenia Space’s Spacebus platform for geostationary telecommunications satellites.  Electric propulsion, which uses and is often called “ion thrusters”, is increasingly being used by the commercial spaceContinue reading

Derrière Ascoval, un écosystème local (FR)

Métiers de la ferraille, services à l’industrie, tuberie voisine… : un millier d’emplois sont liés au destin de l’aciérie nordiste, selon les élus et les syndicats.

 Si tout le monde joue le jeu jusqu’au bout, Ascoval peut être sauvée et nous garderons une filière des aciers spéciaux en France », a lâché le président de la région Hauts-de-France Xavier Bertrand, à l’issue de la réunion à Bercy mercredi,  au terme de laquelle le gouvernement s’est accordé un délai d’un mois pour peaufiner le plan de reprise. De fait, au-delà de la seule aciérie nordiste et de ses 281 salariés, c’est tout un écosystème industriel qui Continue reading

Rhenium : A Critical Rare Metal for the Military Engines For Jet Fighters (US)

Roughly 52,000 kilograms, or 52 metric tons, of rhenium was produced worldwide during 2017. The United States is by far the largest consumer of this critical mineral, accounting for 42,600 metric tons, or nearly 82 percent, of last year’s global production. Nearly 80 percent of the rhenium consumed in the United States is used in superalloys vital to highly efficient jet turbine engines. “The high-temperature properties of rhenium allow turbine engines to be designed with closer tolerances, thus enabling increased thrust and higher operating efficiency,” the USGS explains. The turbine engines in older generation U.S. military aircrafts, such as the F-15 and F-16 fighters, were made from a nickel-based superalloy containing 3 percent rhenium. The turbines in newer generation fighters, such as the F-22 and F-35, contain 6 percent rhenium. The higher rhenium content alloys and limited supply pushed the price of rhenium to a high of US$10,600 per kilogram before the markets crashed in 2009.

Enormous copper-gold deposit in Alaska contains enough of this superalloy metal to supply global needs for 40 years. With a melting point of 5,756 degrees Fahrenheit and a heat-stable crystalline structure, rhenium is extremely resistant to both heat and wear. This durability makes it a vital element in superalloys used in jet and industrial gas turbine engines. “The high-temperature properties of rhenium allow turbine engines to be designed with finer tolerances and operate at temperatures higher than those of engines constructed with other materials,” the United Continue reading
