Heat Resistance

 

the ability of building materials (mainly metal, but also ceramic and polymeric materials) to withstand mechanical stress without substantial deformations and without failure at high temperatures. Heat resistance is determined by a group of properties, including resistance to creep, prolonged distortion, and oxidation. It is characterized as the longterm strength limit (the greatest mechanical stress endured by the material without failure at a given temperature, test duration, and working atmosphere), the creep limit (the stress that causes a given rate of deformation for some particular period of time at a given temperature), and sometimes the period of time before failure for a given stress, temperature, and working atmosphere.
