TIMETAL 35A is equivalent to ASTM Grade 1. It has the highest purity, lowest strength, and best room-temperature ductility and formability of the four ASTM commercially pure grades. TIMETAL 35A should be used where maximum formability is required such as in explosive bonding and plate type heat exchangers. It exhibits excellent corr osion resistance in highly oxidizing to mildly reducing environments, including chlorides. TIMETAL 35A is typically used in continuous service up to 800°F (425°C) and in intermittent service up to 1000°F (540°C). It also has good impact properties at low temperatures. In addition TIMETAL 35A can be easily welded, machined, cold worked, hot worked, and cast.
