(Specification)Standard Specification for Forged Steel Rolls Used for Corrugating Paper Machinery
Standard Specification for Forged Steel Rolls Used for Corrugating Paper Machinery
SCOPE
1.1 This specification2 covers two kinds of rolls used in machinery for producing corrugated paperboard. Rolls are fabricated of forged bodies and trunnions. The trunnions may be bolted or shrink assembled on one or both ends of the body. A seal weld may be made at the body/trunnion interface. Roll shells are made of carbon/manganese, or low alloy steel as hereinafter described, and are heat treated prior to assembly. Pressure rolls may be ordered surface hardened as Condition H, or without surface hardening as Condition S. Provision is made in Supplementary Requirements S1 and S3 for the optional surface hardening of corrugating rolls.
1.2 Corrugating and pressure rolls made to this specification shall not exceed 30 in. [760 mm] in inside diameter. The wall thickness of the roll body shall not be less than 1/12 of the inside diameter or 1 in. [25 mm], whichever is greater, but shall not exceed 4 in. [100 mm]. The wall thickness of the corrugating roll is measured at the bottom of the corrugations in the location of the trunnion fit. The maximum design temperature (MDT) of the roll is 600°F [315°C] and the maximum allowable working pressure (MAWP) is 250 psi [1.7 MPa]. The minimum design temperature shall be 40°F [4°C] for roll wall thicknesses up to 3 in. [75 mm]. For roll wall thicknesses over 3 in. [75 mm] to 4 in. [100 mm], the minimum design temperature shall be 120°F [50°C]. The maximum stresses on the roll bodies from the combined internal and external loading are limited to 18 750 psi [129 MPa] for the Class 2 pressure roll bodies, and 20 000 psi [138 MPa] for Class 1A, 1B, or 5 pressure or corrugating roll bodies in Grades 1 or 2. For the trunnions, the maximum stresses from the combined internal and external loading are limited to 15 000 psi [103.4 MPa] for Classes 3 or 4, or 20 000 psi [138 MPa] for Classes 1A, 1B, or 5 in Grade 2 only. The Grade 1 strength level is not permissible for trunnions.
1.3 Referring to Table 1, material to Classes 1A, 1B, or 5 shall be used for the manufacture of corrugating or pressure roll shells, and Class 2 shall be used only for pressure roll shells. Trunnions shall be made from forgings in Classes 1A, 1B, or 5 in Grade 2 strength level as restricted by Footnote B in Table 2 or in forgings in either Class 3 or 4. (A) When vacuum carbon deoxidation (VCD) is used the silicon content shall be 0.10 % maximum. (A) 0.2 % offset.(B) For trunnion application, a maximum tensile strength of 125 ksi [860 MPa] applies for Grade 2 of Classes 1A, 1B, or 5.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.
1.6 Except as specifically required in this standard, all of the provisions of Specification A788/A788M apply.

1. Scope*Scope
1.1 This specification covers two kinds of rolls used in machinery for producing corrugated paperboard. Rolls are fabricated
of forged bodies and trunnions. The trunnions may be bolted or shrink assembled on one or both ends of the body. A seal weld
may be made at the body/trunnion interface. Roll shells are made of carbon/manganese, or low alloy steel as hereinafter described,
and are heat treated prior to assembly. Pressure rolls may be ordered surface hardened as Condition H, or without surface hardening
as Condition S. Provision is made in Supplementary Requirements S1and S1 and S3 for the optional surface hardening of
corrugating rolls.
1.2 Corrugating and pressure rolls made to this specification shall not exceed 30 in. [760 mm] in inside diameter. The wall
thickness of the roll body shall not be less than ⁄12 of the inside diameter or 1 in. [25 mm], whichever is greater, but shall not
exceed 4 in. [100 mm]. The wall thickness of the corrugating roll is measured at the bottom of the corrugations in the location of
the trunnion fit. The maximum design temperature (MDT) of the roll is 600°F [315°C] and the maximum allowable working
pressure (MAWP) is 250 psi [1.7 MPa]. The minimum design temperature shall be 40°F [4°C] for roll wall thicknesses up to 3
in. [75 mm]. For roll wall thicknesses over 3 in. [75 mm] to 4 in. [100 mm], the minimum design temperature shall be 120°F
[50°C]. The maximum stresses on the roll bodies from the combined internal and external loading are limited to 18 750 psi [129
MPa] for the Class 2 pressure roll bodies, and 20 000 psi [138 MPa] for Class 1A, 1B, or 5 pressure or corrugating roll bodies
in Grades 1 or 2. For the trunnions, the maximum stresses from the combined internal and external loading are limited to 15 000
psi [103.4 MPa] for Classes 3 or 4, or 20 000 psi [138 MPa] for Classes 1A, 1B, or 5 in Grade 2 only. The Grade 1 strength level
is not permissible for trunnions.
1.3 Referring to Table 1, material to Classes 1A, 1B, or 5 shall be used for the manufacture of corrugating or pressure roll shells,
and Class 2 shall be used only for pressure roll shells. Trunnions shall be made from forgings in Classes 1A, 1B, or 5 in Grade
2 strength level as restricted by Footnote B in Table 2 or in forgings in either Class 3 or 4.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
1.5 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound
units.
1.6 Except as specifically required in this standard, all of the provisions of Specification A788/A788M apply.

3. Ordering Information
3.1 Material supplied to this specification shall conform to the requirements of Specification A788/A788M, which outlines
additional ordering information, manufacturing requirements, testing and retesting methods and procedures, marking, certification,
product analysis variations and additional supplementary requirements.
3.2 In addition to the ordering requirements of requirementsof Specification A788/A788M, the purchaser shall include the
maximum design temperature (MDT), if lower than 600 °F [315 °C], 600°F [315°C], and the maximum allowable working
pressure (MAWP), if lower than 250 psi [1.7 MPa] as allowed in 1.21.2 of the Scope.
3.3 When ordering pressure rolls the purchaser shall stipulate the required condition, either surface hardened (Condition H) or
as heat treated (Condition S). In the event that the condition is not specified the default condition is H.
3.4 If a corrugating roll is required to be surface hardened by the forging supplier, prior to forming the flutes by the purchaser,
the requirements of Supplementary requirement S1 shall apply.
3.5 If the requirements of this specification are in conflict with the requirements of Specification A788/A788M, then the
requirements of this specification shall prevail.
4. Materials and Manufacture
4.1 Forging Process:
4.1.1 Roll body forgings may be made as solid forgings and subsequently bored.
4.1.2 Trunnions or gudgeons which are to be subsequently assembled to form the roll shall be made as a solid forging or where
practical upset from segments cut from billets or bars.

mechanical properties instead provided the forging is tested in accordance with 6.1.2.2.
4.2.1.2 Roll bodies shall be normalized, liquid quenched, and tempered to produce the required mechanical properties, except
that for Class 2 forgings, and when Grade 2 strength requirements are specified, a normalize and temper heat treatment may be
