Table 1: Maximum allowable operating temperatures for common materials used in rupture disks and sealing films. Maximum allowable operating temperature of rupture disk materials (°C): Aluminum – 100; Copper – 200; Nickel – 400; Austenitic stainless steel – 450; Monel 430; Inconel – 480; Hastelloy – 480; Graphite – 200. Note: When the surface of a rupture disk is covered with a sealing film or protective layer, the effect of such covering materials on the operating temperature must be taken into account. Table 2 Allowable temperature range for common sealing film materials used in explosives. Allowable temperature range for sealing film materials (°C): Polytetrafluoroethylene – 40–260; Perfluoroalkoxyethylene – 40–200; Aluminum – 196–400; Nickel – 196–530; Austenitic stainless steel – 196–530
