Abrasion loss is determined by measuring the amount of degraded material passing a 1.18mm (No. 16) or 75µm (No. 200) sieve after the test. Materials yielding a low loss in the test are unlikely to show significant degradation during handling, mixing, or placing, and will …Read more

Mangalloy was created by Robert Hadfield in 1882, becoming the first alloy steel to both become a commercial success and to exhibit behavior radically differing from carbon steel.Thus, it is generally considered to mark the birth of alloy steels. Benjamin Huntsman was one of the first to begin adding other metals to steel. His process of making crucible steel, invented in 1740, was the first ...Read more

The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these factors are significant.Read more
