ASTM B753-07(2018)

Annotation of standard text ASTM B753-07(2018) :

This specification details the requirements for alloys to be used as components in the manufacture of bonded multi-component thermostat metal strip. It describes alloys having composition, and thermal expansion suitable for application in thermostat metal sheet and strip. The material shall be free of scale, slivers, cracks, seams, corrosion and other defects as best commercial practice will permit. Surfaces shall be uniform and sufficiently clean. Product surface condition can be agreed upon between supplier and purchaser since surface condition can vary for different alloys and because bonding practices vary. The material shall be made of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, copper, aluminum, cobalt, and iron. This product shall be supplied in the condition agreed upon by purchaser and seller. Hardness shall be measured on representative samples from each heat treat lot.
