ASTM A792 / A792M-097

Standard Specification for Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot Dip Process>

Scope

• This specification covers 55% aluminum-zinc alloy- coated steel sheet in coils and cut lengths.
• This product is intended for applications requiring corrosion resistance or heat resistance, or both.
• This product is produced in a number of designations, types, and grades which are designed to be compatible with differing application requirements.

Terminology

• Definitions-See Terminology A902 for definitions of general terminology relating to metallic-coated hot-dip products.
• Definition of Term Specific to This Standard.
• Regular spangle-the unaltered 55% aluminum-zinc(Al-Zn) crystal structure that occurs during normal solidification of a hot-dip coated steel sheet.

Classification

• The material is available in several designations, as follows;
• Commercial Steel-CS Type A, B, and C,
• Forming Steel-FS
• Drawing Steel-DS
• High Temperature Steel-HTS, and}
• Structural Steel-SS.
• Structural steel is available in several grades based on yield strengths and tensile strength.
• The product is available in several coating weights [masses]with the coating designation.

Coating Designation and Minimum Coating Test Limits

EN 10215/1995

Continuously Hot-Dip Aluminum-(AZ)Coated Steel Sheet and Strip(Technical Delivery Conditions)

1. Grades and Mechanical Properties of Low Carbon steels for Cold Forming

1) The values apply to transverse test pieces
2) The yield strength values apply to the 0.2% proof stress if the yield point is not pronounced, otherwise to the lower yield strength(ReL)
3) For all steel grades a minimum value of 140 N/mm2 for the yield strength (Re) and of 270 N/mm² for the tensile strength (Rm) may be expected
4) For product thickness <0.7mm the minimum elongation values(A80)shall be reducedby 2 units
5) This value applies to skin passed products only(surface qualities B and C)

2.Grades and Mechanical Properties of Structural Steels

1) The values apply to transverse test pieces
2) The yield strength values apply to the 0.2% proof stress if the yield point is not pronounced, otherwise to the upper yield strength(ReH)
3) For product thickness < 0.7mm the minimum elongation values(A80) shall be reduced by 2 units

3. Coating Mas

1) A coating mass of 100 g/m2 corresponds go a coating thickness of approximately 13.3µm on
