ASTM A148 Standard for High
Strength Cast Steel
ASTM A148/A148M-1998
This
sheet is providing the chemical components and
physical properties for the high strength cast steel
by standard of ASTM A148. Moreover, we listed the
old steel grades as the comparison for you.
Chemical Composition
The steel shall conform to sulfur and phosphorus
requirements as the following.
The
content of carbon, manganese, silicon, and alloying
elements may be agreement, be prescribed by the
purchaser. If not specified, the content may be
selected by the manufacturer to obtain the required
mechanical properties.
When
the analysis of carbon, manganese, silicon, or any
intentionally added alloying element is specifically
requested in the contract or order, it shall be made
by the manufacturer and reported to the purchaser.
The results of these analyses shall not be used as a
basis for rejection except by prior agreement.
