Types of alloy steelThere are two kinds of alloy steel – low-alloy steel and high-alloy steel. As mentioned earlier, the composition and proportion of alloying elements determine the various properties of alloy steel. Low-alloy steels are the ones which have up to 8% alloying elements whereas high-alloy steels have more than 8% alloying elements. Alloying elements There are around 20 alloying elements that can be added to carbon steel to produce various grades of alloy steel. These provide different types of properties. Some of the elements used and their effects include: Aluminium – can rid steel of phosphorous, sulfur and oxygenChromium – can increase toughness, hardness and wear resistanceCopper – can increase corrosion resistance and harnessManganese ...

New disordered materials show exceptional hardness and heat toleranceA new class of complex ‘high-entropy’ metal carbides that incorporate five different metals has been developed by researchers in the US, who have shown the new materials can be significantly harder and more heat resistant than simple carbides.Metal carbides such as tungsten or titanium carbide are valued for their toughness and high melting points, and are widely used in mining tools and thermal protection coatings. But most carbides used today consist of just one metal cation combined with carbon. ‘These “binary” carbides ar...

Tungsten, also known as wolfram, has many uses. It is commonly used to produce electrical wires, heating and electrical contacts.But it is also used in welding, heavy metal alloys, heat sinks, turbine blades and as a substitute for lead in bullets.According to the most recent US Geological Survey report on the metal, world tungsten production came in at 95,000 MT in 2017, up from 2016’s 88,100 MT.This increase came despite reduced output from Mongolia, Rwanda and Spain. A large boost in production came from the UK, where production increased around 50 percent.The ...

Booth Number:C090Shimadzu has announced the release of three models of the GCMS NX series gas chromatograph mass spectrometers. The new NX series, which consists of the GCMS-TQ8050 NX, the GCMS-TQ8040 NX, and the GCMS-QP2020 NX, combines the features of high accuracy and high sensitivity, with ease of maintenance, and improved operating efficiency. The GCMS NX series will be exhibited at JASIS, which will be held at Makuhari Messe from September 5 to 7.Gas chromatograph mass spectrometers (GC-MS) are used for quantitative analyses to check for the presence of environmental contaminants and res...

The Japanese MIM industry has reported its first growth in output for seven years, with sales rising to Yen 11.74 billion ($103.5 million) in 2017 – a healthy increase of 14.5% compared with the previous year (Fig. 1). According to the Japan Powder Metallurgy Association, which collects statistical data from the twenty-one companies involved in MIM production in the country, the rise in sales can be attributed to the generally healthy state of the global economy, and several of Japan’s MIM producers have indicated plans to expand production capacity to meet increasing demand. FIG 01&...
