7.0 MECHANICAL PROPERTIES
7.1 Tensile Properties - (Specimen 1E0552-X1, X2, X6, or X9) shall be as follows:
Yield Strength
207 MPa MIN
7.2 For sheet and strip that “MAY BE FULFILLED BY 1E0166”, the minimum yield strength
will be approximately 170 MPa.
8.0 SAMPLES
A random sample 450 mm long from each heat of special rolled channel sections may be
required to be shipped suitably identified, to the metallurgical division of the procuring Caterpillar
Inc. plant.
9.0 SUBSTITUTE MATERIALS
9.1 Substitute materials allow the chemical compositions of certain National Standard grade
steels to be used in place of 1E specification chemistries, per the guidelines of 1E0024 and
1E2349 - Substitute Materials Application. When procuring any of the following substitute
grades, all other quality requirements of the original 1E Specification shall be met, such
as approved mill, reduction ratio, caster class, tensile strength, DI, grain size, etc.
9.2 If steel purchasers do not understand these issues, they shall buy materials to the 1E
material specification or employ the services of Caterpillar Global Purchasing to assist in
material acquisition.
9.3 1E2349 governs approval requirements and procedures. This specification shall be read
and understood before using any of the substitute materials listed below.
