Short-Term Creep in Electrical-Engineering Steel

摘要

On the basis of experiments on the short-term creep of 33 A electrical-engineering steel strip during heating to 1000 deg C, we obtain approximate formulas for the conditional creep limit as a function of the temperature and for the creep rate as a function of the temperature and tensile stress. These results may be used to determine the tensile stress and extension coefficient of strip in drying units for electrically insulating coatings on steel strip.
