European standard steel grade names fall into two categories: [1] Steel specified by purpose of use and mechanical properties. Steel specified by chemical composition. The inclusion of a letter 'G' before the code indicates the steel is specified in the form of a casting.

A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, [1] copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell and engages the barrel's ...
Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese , medium-carbon steel or high-carbon steel with a very high yield strength .
For the study, the researchers analyzed 284 tissue samples from 83 people between the ages of nine and 70. Overall, they looked at five types of tissue samples and stacked them up against seven ...
John Sykes, a veteran hard-rock guitarist who was a member of Whitesnake, Thin Lizzy and the Tygers of Pan Tang, has died, according to a post on his official Facebook page. He had battled cancer ...
Schematic of a slip band, relative to the measurement axes (𝑥 1, 𝑥 2, and 𝑥 3), and axes related to the slip-band (𝑥, 𝑦, and 𝑧), showing the angles that describe the relationship between these axes and the traces of the slip band (𝛼, 𝜃), and the inclination angle (𝜓) of the slip trace (𝑥) and Burgers vector (𝑏 ...
Electrical steel is usually coated to increase electrical resistance between laminations, reducing eddy currents, to provide resistance to corrosion or rust, and to act as a lubricant during die cutting. There are various coatings, organic and inorganic, and the coating used depends on the application of the steel. [11]
