A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. Values in inch-pound and SI units are not necessarily equivalent.
Within the text, SI units are shown in brackets. Each system shall be used independently of the other. These notes and footnotes excluding those in tables and gures shall not be considered as requirements of the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Referenced Documents 2. Current edition approved April 1, Published May Originally approved in Terminology 3. Classication 4. It is intended principally for heatresisting applications and also for uses where corrosion resistance and heat are involved. It is available as a coating on each of the designations of steel sheet listed in 4. Because of the many variables and changing conditions that are characteristic of continuous hot-dip coating lines, the weight [mass] of coating is not always evenly divided between the two surfaces of a sheet, nor is the coating evenly distributed from edge to edge.
B No minimum means that there are no established minimum requirements for triple- and single-spot tests, but aluminum coating shall be present.
It is intended principally for use in applications requiring corrosion resistance and is available only as a coating on Commercial Steel, Forming Steel, Structural Steel, and High Strength-Low Alloy Steel. Ordering Information 5. The following, as required, shall be used to adequately describe the product required.
Chemical Composition 6. When the amount of vanadium, titanium, or columbium is less than 0. Mechanical Properties 7. These mechanical property values are nonmandatory. CbC 0. The sum of copper, nickel, chromium, and molybdenum shall not exceed 0. When one or more of these elements are specied, the sum does not apply; in which case, only the individual limits on the remaining elements shall apply. This requirement does not apply to Types and C For steels having a carbon content of 0.
E CS Type B describes the typical commercial quality product previously included in this specication. F When a deoxidized steel is required for the application, the purchaser has to option to order CS to a minimum of 0.
I Shall be furnished as a stabilized steel. J Shall contain silicon 1. K Shall contain silicon 1. The sum of copper, nickel, chromium and molybdenum shall not exceed 0.
When one or more of these elements are specied the sum does not apply; in which case, only the individual limits on the remaining elements shall apply. D For steels having a carbon content of 0. E Steel conforming to this designation commonly contains the strengthening elements columbium, nitrogen, phosphorus, or vanadium added singly or in combination.
Values outside these ranges are to be expected. There are many interrelated factors that affect the ability of a steel to cold form over a given radius under shop conditions. If the hardness result is 85 HRB or higher, no tension test is required. C As there is no discontinuous yield curve, the yield strength should be taken as the stress at 0. D If a higher tensile strength is required, the user should consult the producer.
They are intended solely to provide the purchaser with as much information as possible to make an informed decision on the steel to be specied. Values outside of these ranges are to be expected.
The purchaser may negotiate with the supplier if a specic range or a more restrictive range is required for the application. B These typical mechanical properties apply to the full range of steel sheet thicknesses. The yield strength tends to increase and some of the formability values tend to decrease as the sheet thickness decreases. E No typical mechanical properties have been established. This is not considered to be a fault of the steel but is rather a function of the induced cold-work.
Coating Properties 8. For all designations the coating bend test inside diameter shall be equal to twice the thickness of the specimen. Flaking of the coating within 0. Dimensions and Permissible Variations 9.
Keywords All other values in Table X2. B Weight [mass] to thickness conversions are reliable to only two signicant gures.
Inch-pound to SI conversions are reliable to ve signicant gures. A greater number of digits are shown in Table X2. A One ounce of Type 2 aluminum coating per square foot of surface corresponds to an average coating thickness of 0.
The former designations also did not reect the availability of new steels that are the result of the use of new technologies, such as vacuum degassing and steel ladle treatments.
The new designations are dened with technical information, such as specic chemical composition limits and typical nonmandatory mechanical properties. These steel characteristics are important to users concerned with the weldability and formability of the coated steel products.
The typical mechanical properties included in the new designation system are those indicated by the tension test. These properties are more predictive of steel formability than other tests, such as the hardness test, which may not compensate adequately for product variables such as substrate thickness and coating weight. Some of the reasons for this limited relationship are the following: the addition of steels not previously described in ASTM specications; restrictions placed on ranges of chemical composition; the addition of typical mechanical properties; and the enhanced capability of steel producers to combine chemical composition and processing methods to achieve properties tailored to specic applications.
Continuing dialogue between users and producers will have to be maintained to assist in the transition to the new designation system. A user with concerns about the appropriate coated steel to order for a specic application should consult with a steel supplier or producer. April 1, 1 Revised 4.
