ASTM A487 A487M for
Steel Castings made by Steel Foundry in China
ASTM A487 grades include 1, 2, 3, 4,
5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, CA15, CA15M, CA6NM, the
following is their chemical requirements.
This specification covers low-alloy steel and martensitic stainless
steels in the normalized and tempered, or quenched and tempered
conditions, suitable for pressure-containing parts.
All castings shall receive the specified heat treatment requirement:
austenitizing temperature, medium, quenching cool, and tempering
temperature.
The steel shall conform to the required chemical composition for
carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium,
molybdenum, vanadium, boron, and copper. Residual elements include:
copper, nickel, chromium, tungsten, molybdenum, and vanadium.
Tensile properties of the steel shall conform to the requirements
for tensile strength, yield strength, elongation, reduction of area,
hardness, and maximum thickness. Product analysis tolerance is
specified. Repair by welding may be done.
