Abrasion (mechanical) - Wikipedia

Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index). The former is the amount of mass lost per 1000 cycles of abrasion. The latter is the ratio of former with the known abrasion rate for some 【Get Price】

species, properties and uses - Hyne Timber

Hardness is a measure of a species resistance to indentation, wear or abrasion. It also gives an indication of the difficulty of sawing and planing. It is measured in kN and is determined by the Janka hardness test (the higher the number, the greater hardness). TOUGHNESS. Toughness is a measure of timbers ability to resist 【Get Price】

What is Abrasion Resistance? - Definition from Corrosionpedia

Abrasion-resistant materials are handy in inhibiting mechanical wearing and damage. They can be used in the construction of space shuttle components. The abrasion resistance of high-performance concrete is high. This concrete containing silica-fume is useful for concrete pavement overlays where heavy or abrasive 【Get Price】

High Carbon Abrasive Resistant Steel - AR400, AR450, AR500 O

Abrasion Resistant Steel. High carbon abrasive resistant alloy steel plates generally offer good resistance to sliding and impact abrasion. The high carbon content in the alloy increases the hardness and toughness of the steel, making it an ideal material for applications that require high impact or high abrasion resistance. 【Get Price】
