Standard Specification for Pressure Vessel Plates, Alloy Steel, Quenched and Tempered Nickel-Chromium-Molybdenum
|Publication Date:||1 October 2009|
|ICS Code (Steels for pressure purposes):||77.140.30|
This specification2 covers nickel-chromiummolyb
Material under this specification is available in two types, B and C.
The maximum thickness of plates is limited only by the capacity of the chemical composition to meet the specified mechanical property requirements.
The minimum plate thickness is 3⁄16 in. [5 mm].
These alloy steel plates in the as-rolled condition are sensitive to cracking during flame cutting, transit, and handling. They should be shipped in the as-rolled condition only with the mutual agreement of the manufacturer and the purchaser or fabricator.
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
