Rising demand to push steel production in Saudi Arabia

The Saudi Gazette reported that Saudi Arabia's domestic steel production will grow at a CAGR of around 14% to 2013 on the back of rising steel demand. The report provides a detailed study of the steel industry outlook in Saudi Arabia till 2015. The report noted that the consumption of steel is anticipated to gain an uninterrupted momentum from the government backed massive infrastructure projects. Government sources said that an estimated USD 400 billion investment will be spent on large infrastructure projects during the next 5 years. This will further boost the steel demand in the country and take iron and steel consumption to over 26 million tonnes by 2015. The Kingdom has shown strong resilience against the economic slowdown, the report said. As a result, Saudi Arabia's steel industry is once again striving hard to achieve exponential growth trajectory and many steel manufacturers have started formulating capacity expansion strategies in response to the fast growing dome...

Brief summary of effects of alloying elements on Steel

The following information on brief summary of effects of alloying elements on steel is provided for practicing engineers, NDT trainees and ndtians/technicians and quality control engineers in order to understand and apply these uses for practical related case studies. S teels are among the most commonly used alloys. The complexity of steel alloys is fairly significant.  Not all effects of the varying elements are included. The following text gives an overview of some of the effects of various alloying elements.  Additional research should be performed prior to making any design or engineering conclusions. Alloying Elements: Carbon: has a major effect on steel properties.  Carbon is the primary hardening element in steel.  Hardness and tensile strength increases as carbon content increases up to about 0.85%.  Ductility and weldability decrease with increasing carbon.  Manganese:   Is generally beneficial to surface quality especially in resulfu...

Earths Magnetic North Pole Shifts - Runway closure at Florida Airport

Image
An airport in Tampa, Florida, has had to temporarily close its runways to keep up with Earth's magnetic north pole, which is drifting toward Russia at a rate of 40miles per year .    Fox News Reports that the international airport was forced to adjust the signs on its busiest runway Thursday because pilots depend on the magnetic fields to navigate. The runway will be closed until Jan. 13, and will re-open with new taxiway signs that indicate its new location on aviation charts, the Tampa Bay Tribune Reports. Paul Takemoto, a spokesman for the FAA , says the Earth's magnetic fields are constantly in flux -- but rarely so much so that runway signage needs to be changed. "You want to be absolutely precise in your compass heading," he told Fox. "To make sure the precision is there that we need, you have to make these changes." "The Earth's poles are changing constan...

Down the Memory Lane - 'KANISHKA' lecture by Former Deputy Director & Emeritus Scientist

An interesting lecture "Down the Memory Lane - 'KANISHKA'  Revisited" is delivered on 01st July 2010 by Mr. Dr.V.Ramachandran,  Former Deputy Director & Emeritus Scientist, National Aerospace Laboratories, Bangalore at Indian Institute of Science, Bangalore, India. It has been organized by Indian Institute of Metals, Bangalore Chapter. The completed session is quite interesting and has been attended by many research scholars and industry experts. Some of the excerpts are as follows On June 23, 1985, Boeing 747 aircraft “KANISHKA” of Air India, on a scheduled flight from Montreal to London en route to Delhi and Bombay, suddenly plunged, from an altitude of 31000 feet, into the Atlantic Ocean, at a spot about 110 miles west of Ireland, killing all the 329 occupants on board. It was the worst accident in the history of Indian civil aviation. The investigation of the accident posed many challenges in management, coordination and technical. The speaker, as a Member o...
