Marking of Metal Products

Scope

This specification covers the requirements for minimum identification marking of metal products. These marking requirements are in addition to ASTM A700 and other marking requirements that may be specified in the purchase order or in separate shipping instructions.

Conflicts and Deviations

2.1

Any conflicts between this document and other applicable Mandatory Saudi Aramco Engineering Requirements (MSAERs) shall be addressed to the EK&RD Coordinator.

2.2

Any deviation from the requirements herein shall follow internal company procedure SAEP-302.

References

The selection of material and equipment, and the design, construction, maintenance, and repair of equipment and facilities covered by this specification shall comply with the latest edition of the references listed below, unless otherwise noted.

General

4.1

Objective

Since the use of metals other than those specified for any given application may lead to rapid failure, resulting in a hazard to both life and property, it is essential that the risk of incorrect identification of the metals be reduced to a minimum by marking in accordance with this specification.

4.2

General Requirement

Metal products ordered to ASTM or equivalent other specification shall, as a minimum, be marked in accordance with such specification and, in addition, as further specified below.

4.3

Specification References

Reference is made in this specification to standards mentioned in paragraph 3.2.

Marking Terms

5.1

Vendor’s Name or Trade Mark

The vendor’s name or registered trade mark used shall be that of the manufacturer who performs the final processing or finishing operation prior to marketing the product.

5.2

Commercial Designation

5.2.1 The commercial designation shall include a designator of material type,

grade and a designator of physical conditions, temper and/or quality.

5.2.2 The material designations shall include the applicable ASTM, AISI,

DIN, JIS, ISO, BSI, or EN specification numbers or numbers of equivalent specifications.

5.2.3 Each product or secured lift shall be tagged or marked with the heat number, the size, and customer’s name and order number.

Marking of Metal Products

Marking Requirements and Applications

6.1 Marking Methods and Legibility

6.1.1 The area of the metal products to be marked shall be clean and dry.

6.1.2 Markings on metal products shall be legible and sufficient to resist effacement by contact incidental to normal handling, shipment and outside storage. Quick drying, permanent waterproof ink, paint, other suitable marking substances or electrochemical marking may be used. Marking substances (ink, paint, etc.) shall be compatible with the chemistry of the marked component. Stamping is permitted on carbon steel products except ground bars.

6.1.3 The size of the lettering shall be consistent with the space available to be

marked on metal products.

6.1.4 When tags are used they shall be made of a durable non-corroding material with markings that remain legible after prolonged outdoor storage. Stamping is the preferred method for marking on metal tags.

6.1.5 Generally, there is no recognized color code for identification of steel grades, color marking to denote special grades can be applied. In such cases, a dash of color on one end of loose pieces is sufficient.

6.1.6

In the case of secured lifts, the grade is shown on a tag attached to the lift. If specified, the lift is marked additionally on one end of the lift with sizes of 0.05 meter and over with not more than two colors.

6.2

Deleterious Effect

Marking on metal products shall be placed in a manner which will not affect the usefulness of the product and will not be easily vanished by contact.

6.3 Marking Frequency

The following requirements for frequency of metal identification marking consider handling, packaging, and the likelihood of identification problems when metal products are cut in the storehouse or at the construction site. Minimum marking frequencies are given in the following paragraphs.

6.3.1 Mild carbon steel plate shall be marked at one location on each piece as shown in Figure 1. High-strength low-alloy steel plate shall be marked on one place on each piece. Alloy and stainless steel plates, and nonferrous plates shall be marked in rows of recurring marks at intervals not greater than 1 meter on one face and one end of each plate.

Marking of Metal Products

6.3.2 Coated and uncoated mild carbon steel sheet and strip shall be marked at

one location on the top piece of each lift or shipping unit. Alloy steel and stainless steel sheet, and strip and non-ferrous sheet metals shall be marked at each corner of one face of each piece or in rows of recurring marks at intervals not greater than 1meter on one face and one end of each piece.

6.3.3 Alloy steel, stainless steel and non-ferrous bar, tube stock and keystock

shall be marked at intervals not greater than 1 m throughout the length of each bar.

6.3.4 Bundled carbon steel bars and shapes shall be marked with two tags

firmly attached to each end of the bundle as shown in Figure 1 of this specification.

6.3.5 Carbon steel bars and shapes that are not bundled shall be marked at one

end of each bar.

6.3.6 Castings shall be marked in at least one location on the surface of each

piece; such markings may be cast in place.

6.3.7 Single and slit coils, and sheets in banded shipping units shall be tagged

as shown in Figure 1 of this specification and marked with a dash of color, if specified, as explained in 6.1.5.

Revision Summary

18 June 2014

1 July 2019

Major revision to update the requirements of marking for metal products. These changes enhance the identification of procured materials and traceability. Major revision to address e-Standards comments and internal committee review. In addition, modified Section 2 to address EK&RD for any conflict between SAMSS and MSAERs, and to follow SAEP-302 for any deviation. Added ASTM A700 in the main text. Added AISI to the Industry Coded and Standards Terminology. Eliminated the dual numbering and used the SI units per SAEP-301.
