Hardness Testing of Materials

Summary. Hardness testing is a test to measure the resistance and stress of the material for bending, penetration, scratching, or abrasion. the most commonly used hardiness tests are those that measure the resistance to penetration of the material. Some of the testers and scales that can be use for hardness testing are Rockwell BC, Shore AD,...

Mechanical Properties of Gray Cast Iron Tensile Strength ...

Mechanical Properties of Gray Cast Iron. The American Society for Testing Materials ( ASTM) numbering system for grey cast iron is established such that the numbers corespond to the minimum tensile strength in kpsi. Thus an ASTM no. 20 cast iron has a minimum tensile strength of 20 kpsi. Note particularly that the tabulations are typical values.
