When all elements in Table 1 are analyzed, their sum shall be as follows: Steel ingot is the cast metal with porosity and blow-holes.
Nickel additions in these alloys allow designers to benefit from attractive color options ranging from light rose to silver. This standard has been approved for use by agencies of the Department of Defense. The B and F scale hardness values apply to metal 0.
Offering unique properties such as excellent resistance to biological fouling, corrosion and stress corrosion cracking, these alloys are used in a range of applications from heat exchangers, ship components and condenser tubes of power plants to coinage and even touch surfaces on medical equipment. C 3 65 10 Cupro-Nickel are among the most attractive, durable and versatile copper alloys available.
This specification also contains information on the standard tempers for and tensile strengths of hot-rolled, cold-rolled, and annealed tempers. Siddhagiri Metals and Tubes Rating: A billet is rolled out of bloom, has at least 40 mm X 40 mm cross-section. C are required, see appropriate table.

Limits may be established for unnamed elements by agreement between manufacturer or supplier and purchaser.
C 2 65 18 asmt A number in parentheses indicates the year of last reapproval. Billets are rolled into bars, rods. Materials and Manufacture 6. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Each product should be manufactured by hot or cold working, and annealed if required, to produce a uniform wrought g122 that meets the specified temper properties. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service qstm. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Cupro Nickel Alloy with small amounts of iron and manganese improves corrosion resistance in high-velocity waters, including seawater.

Both processes can produce ingots which are rolled into blooms or billets or strand cast blooms or billets. A slab, also from ingot, has a rectangular cross-section, with an area of at least cm2 and width at least three times the thickness.
