Abstract: The heat transfer coefficient at the contacting surface of two specimen was calculated. In laboratory, the temperatures of some points on surface of 1Cr18Ni9Ti were measured under the condition of hot non-deforming press. From these data, the heat trans-fer characters of the speciman were analysed. By finite difference technique, the heat trans-fer coefficient of 1Cr18Ni9Ti stainless steel could be obtained.-
