ASTM A436 - 1997 / ASTM A439 - 1999 for Austenitic Cast Iron
This is an America standard for the physical
properties, mechanical properties and chemical analysis of
austenitic cast iron. The types of austenitic cast iron include
austenitic gray cast iron and austenitic
ductile cast iron.
Austenitic gray cast iron has good machinability, corrosion
resistance, heat resistance, acid resistance and alkali resistance.
Austenitic gray castings are widely used in the valve, pump body and
pipe fitting etc. Austenitic ductile cast iron containing 20% - 30%
Ni and it has higher strength and toughness, its tensile strength
can reach 1000 Mpa. Austenitic ductile castings are widely used in
gear and structural components, such as brackets, frameworks and
bases, etc.
The following is the main content of ASTM A436-1997/ASTM A439-1999
