(Specification)Standard Specification for Steel, Sheet, Carbon, and High-Strength, Low-Alloy for Pressure Vessels
Standard Specification for Steel, Sheet, Carbon, and High-Strength, Low-Alloy for Pressure Vessels
ABSTRACT
This specification covers hot-rolled carbon steel sheet for pressure vessels involving fusion welding or brazing. Tensile and yield strengths shall be determined after a tension test of the sheets. The material shall be furnished without removing the hot-rolled oxide or scale. When required, the material may be specified to be pickled or blast cleaned. When specified to be pickled or blast cleaned, the material shall be furnished oiled. When required, pickled or blast-cleaned material may be specified to be furnished dry.
SCOPE
1.1 This specification2 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.

1.3 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 6.1.3. The purchaser should recognize this may require cutting the coils to obtain test samples and results in half-size coils. The sheet is furnished to the following size limits:
Width, in. [mm]
Thickness, in. [mm]
Over 12 [Over 300]

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.
1.5 Tolerances are found in General Requirements Specifications A568/A568M and A635/A635M. The appropriate General Requirements specification is applied based on the thickness and width of the product ordered.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

provided tension test specimens are taken to represent the middle of the slab as required by 6.1.3. The purchaser should recognize
this may require cutting the coils to obtain test samples and results in half-size coils. The sheet is furnished to the following size
limits:

1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions—For definitions of other terms used in this specification refer to Terminology A941.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 lot, n—all coils of one thickness and width combination from one heat and one rolling on the hot mill, up to 100 tons [90
tonnes] total mass.
4. Ordering Information
4.1 Orders for material under this specification shall include the following information, as required, to describe the material
adequately:
4.1.1 Designation or specification number, date of issue, and grade,
4.1.1.1 Grade H may be substituted for Grade G upon agreement between the purchaser and producer,
4.1.2 Copper bearing steel, when required,
4.1.3 Special requirements, if required,
4.1.3.1 Charpy impact properties may be specified for Grade H at the time of order,
4.1.3.2 Strength levels at other than room temperature may be specified for Grade H at the time of order,
4.1.4 Condition—pickled (or blast cleaned), if required (material so ordered will be oiled unless ordered dry), and
4.1.5 Dimensions, including type of edges.
4.1.5.1 When the purchaser requires thickness tolerances for 3⁄8 in. [10 mm] minimum edge distance (see Supplementary
Requirement in Specifications A568/A568M or A635/A635M, as applicable), this requirement shall be specified in the purchase
order or contract.
NOTE 1—Not all producers are capable of meeting all of the limitations of the thickness tolerance tables in Specification A568/A568M or Specification
A635/A635M. The purchaser should contact the producer regarding possible limitations prior to placing an order.
4.1.6 Cast or heat analysis, or test report request, or both, if required.
NOTE 2—A typical ordering description is as follows: “ASTM A414, Grade A, Hot-Rolled Sheet, 0.100 in. [2.54 mm] by 36 in. [914.4 mm] by 96
in. [2438 mm], cut edges.”
5. Chemical Requirements
5.1 Cast or Heat Analysis—The analysis of the steel shall conform to the requirements prescribed in Table 1.
5.1.1 Each of the elements listed in Table 2 shall be included in the report of the heat analysis. When the amount of an element
present is less than 0.02 %, the analysis may be reported as “<0.02 %.”
5.2 Product, Check, or Verification Analysis—Analyses may be made by the purchaser from finished material representing each
heat.
5.3 Deoxidation—For all grades, killed steel is required. See Table 1 and footnote B.
6. Mechanical Property Requirements
6.1 Tensile Strength:
6.1.1 Requirements—Material as represented by the test specimen shall conform to the tensile requirements specified in Table
3. One coil per lot shall have test specimens taken from locations representing the front end, middle, and back end of the coil. If
all tensile results conform to the requirements, other coils of that lot may be tested only at the middle position.
6.1.2 Location and Orientation (see Fig. 1):
