Objects made of electrical insulators like rubber tend to have very high resistance and low conductance, while objects made of electrical conductors like metals tend to have very low resistance and high conductance. Webfor high-temperature service. The characteristics that make some of the stainless steels particularly useful in high-temperature environments are described, and typical engineering data are presented. Also discussed, but as a secondary consideration, are the corrosion-resistance qualities of stainless steels at elevated temperatures. rlink gps tracking system
