Hardness is a measure of a material’s ability to resist abrasion and indentation. For carbon steels Brinell & Rockwell hardness testing can be used to estimate tensile strength. Toughness is a material’s ability to absord impact or shock loading, and is rarely a specification requirement. Ductility is the measurement of a material to deform before it fails and … Read more
It is a process utilized to change certain characteristics of metals and alloys in order to make them more suitable for a particular kind application Heat Treatment can greatly influence mechanical properties such as strength, hardness, ductility, toughness, and wear resistance of the alloys. Heat Treatment of Carbon Steels and Carbon Alloy Steels: Heat Treatment … Read more
There are six things that can be told by looking at the head of a bolt :the type of fastener or drive type ,the grade of the fastener, the manufacture, the material ,the plating or coating and if it is a fractional or metric fastener. These are broken down into groups called grades that classify … Read more
