The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material.The scale was created in 1822 by German geologist and mineralogist Friedrich Mohs; it is one of several definitions of hardness in materials science, some of which are more ...

· The Brinell Hardness of Gray Cast Iron constant displays the value of the Brinell hardness of gray cast iron ASTM A48 Class 40 (235 BHN). Brinell hardness test determines the ability of a metal to resist permanent indentation deformation through the scale of penetration of an indenter that is loaded onto a material sample.. Brinell hardness is one of several definitions of hardness for materials
Brinell hardness of wrought iron is approximately 100 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching. Hardness of Wrought Iron. Many products described as wrought iron, such as guard rails, garden furniture and gates, are actually made of mild steel.
Brinell hardness is a typical hardness specification for cast iron products, especially for ductile iron and gray cast iron. However, in the most international standards, cast iron hardness is not a necessary inspection specification. Only in Chinese standards, we could see the normal Brinell Hardness (HBS) range for common cast iron grades.
The Shore durometer is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials. The term is also used to describe a material''s rating on ...
