(Specification)Standard Specification for Steel, Sheet, Carbon, for Pressure Vessels
Standard Specification for Steel, Sheet, Carbon, for Pressure Vessels
SCOPE
1.1 This specification covers hot-rolled carbon steel sheet for pressure vessels involving fusion welding or brazing. Welding and brazing technique is of fundamental importance and shall be in accordance with commercial practices.
1.2 The following grades are included in this specification: Mechanical RequirementsGradeYield Strength, minTensile Strength, minksiMPa ksiMPaA2517045310B3020550345C3323055380D3524060415E3826065450F4229070485G4531075515
1.3 Hot-rolled carbon steel sheet is generally furnished in cut lengths and to decimal thickness only. Coils may be furnished, provided tension test specimens are taken to represent the middle of the slab as required by . The purchaser should recognize this requires cutting the coils to obtain test samples and results in half-size coils. The sheet is furnished to the following size limits: Width, in.

A For thicknesses greater than 0.230 in. [6.0 mm], the thickness tolerances of Specification A 635/A 635M apply.
1.4 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 shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
