compressive strength of chrome ore

Investment strength as a function of time and temperature

Baseline compressive strength values were determined for each material at room temperature and compressive strength measurements were made for all materials at 700 degrees C, and at 872 degrees C only for phosphate-bonded investments. Each material was tested at 2, 6, 12, and 24 h after mixing. Specimens were heated at 15 degrees C/min and heat ...

What Are The Strongest Metals? - Industrial Metal Supply

Tungsten has the highest tensile strength of any pure metal - up to 500,000 psi at room temperature. Even at very high temperatures over 1,500°C, it has the highest tensile strength. Tungsten is so dense that it resists melting, even under extremely high heat. However, tungsten metal is brittle, making it less useable in its pure state.
