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 ...

Sandia researchers Michael Chandross (left) and Nic Argibay, overseeing the testing of the platinum-gold alloy that's now the world's most durable alloy(Credit: Randy Montoya)Engineers at Sandia National Laboratories have developed what they say is the most durable metal alloy ever created. Made up of a combination of platinum and gold, the new material is apparently 100 times more wear-resistant than high-strength steel, which makes it the first metal alloy to join the same class as diamond. Even better, it naturally produces its own lubricant that, under normal circumstances, ...

Manganese ore imports continue to growGrowing imports of manganese ore continued to buoy supplies of raw materials in 2018, even as environmental issues weighed on domestic production. Imports of manganese ore reached 22.08 million mt in January-October, compared to 21.26 million mt of total imports in 2017. This is likely to increase ore supplies by 15% year on year in 2018. Output of manganese oxide ore shrinks furtherEnvironmental and safety inspections hampered production across medium-sized and small manganese oxide miners in 2018. Even with high profits in the st...

China is getting a step closer to exploring the bottom of the Mariana Trench, the largest crack in the Earth's surface, after the welding of the spherical shell of the submersible's capsule was completed on Saturday.According to Lei Jiafeng, research fellow of the Institute of Metal Research affiliated with the Chinese Academy of Sciences, China is the first country to build such a large deep-sea manned submersible with titanium alloy materials able to last for over 30 years.Upon completion, the submersible, capable of diving to depths of over 10,000 meters, will become one of the most advance...
