Cupro Nickel (UNS C, ASTM B)

Mechanical Property Requirements The molten iron is commonly referred to as hot metal or, in its solid form, as pig iron. The first stream is referred to as the integrated mill stream, which uses mostly iron ore to feed a blast furnace, which in turn supplies hot iron to a steel making operation.

B Scale 68—82 80—90 87—94 89—96 Super? C 8 59 12 Current edition approved May 10, Each product should be manufactured by hot or cold working, and annealed if required, to produce a uniform wrought structure that meets the specified temper properties.

A billet is rolled out of bloom, has at least 40 mm X 40 mm cross-section. Special or nonstandard tempers are subject to negotiation between manufacturer and purchaser See 5. Although no minimum grain size is required, this material shall be fully recrystallized.

When all the elements in Table 1 are analyzed, their sum shall be as follows: C 1 72 18 C 4 55 18 The second is the electric arc furnace EAFwhich primarily uses steel scrap as b1122 raw material. Materials and Manufacture 6. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Nickel additions in these alloys allow designers to benefit from attractive color options ranging from light rose to silver. The values stated in each system are not exact equivalents; therefore, each system shall 1 This speci? Cupro-Nickel are among the most attractive, asmt and versatile copper alloys available.


The ingot is soaked at the hot rolling temperature and then rolled into blooms or billets or slabs. Originally published as B — 39 T. 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.

In case of disagreements, the chemical composition is determined following appropriate methods listed here. C Rockwell hardness values apply as follows: Required properties for other tempers shall be agreed upon between manufacturer and purchaser at the time of placing the order.
