Combining values from the two systems may result in non-conformance with the standard. There are two main production streams that is used to produce rolled bar products. C 5 70 A slab, also asym ingot, has a rectangular cross-section, with an area of at least cm2 and width at least three times the thickness.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. 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. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

b212 Both processes can produce ingots which are rolled into blooms or billets or strand cast blooms or asstm. The following alloys are covered: Current edition approved May 10, C M20 H01 H02 H04 H06 H08 A B as hot-rolled quarter hard half hard hard extra hard spring 60 [] 69 [] 78 [] 92 [] [] [] 80 [] 87 [] 95 [] [] [] [] D Standard designation de? 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.

Dimensions, Mass, and Permissible Variations C 1 72 18 Asttm and Manufacture 6. 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.

Cupro Nickel Alloy with small amounts of iron and manganese improves corrosion resistance in high-velocity waters, including seawater. A superscript epsilon e indicates b212 editorial change since the last revision or reapproval. Such Sheet or Plate is manufactured by hot or cold working, and annealed if required in order to produce a uniform wrought structure to meets the specified temper properties.

Required properties for other tempers shall be agreed upon between manufacturer and purchaser at the time of placing the order. Limits may be established for unnamed elements by agreement between manufacturer or supplier and purchaser. Mechanical Property Requirements C Rockwell hardness values apply as follows: Up to 85 70—90 75—90 80—95 85—95 87—95 92 and over C 6 80 Within the text, the SI units are shown in brackets.
