ASTM A568 Standard Specification for Steel, Sheet, Carbon, Structural, andHigh-Strength, Low Alloy, Hot-Rolled and Cold-Rolled

    What is ASTM A568?

    ASTM A568 describes general standards for coils and cut lengths of steel sheets. These specifications cover structural steel, carbon steel, and hot-rolled and cold-rolled high-Strength low-alloy (HSLA) steel. It’s crucial to remember that hot-rolled, thick carbon sheet coils are not covered by this specification. Should there be any inconsistencies, the requirements listed in the specific material specification will take precedence over the general specification.

    MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM A568 tests for our clients. It’s crucial to remember that hot-rolled, thick carbon sheet coils are not covered by this specification. Should there be any inconsistencies, the requirements listed in the specific material specification will take precedence over the general specification.

    What is the Scope of ASTM A568 Testing? 

    • The test sample must be supplied hot-rolled rather than annealed or pickled.
    • Cold reduction to thickness is followed by annealing a cold-rolled sheet.

    ASTM A568 Testing Procedure and Sample Requirements Guide

    ASTM A568 outlines several test methods, including ASTM A370 for mechanical testing procedures for steel products, ASTM A414 for steel and sheet specification, and ASTM A659 for commercial steel application.

    • Specimen Detail: Steel sheets in cut lengths and coils are specimens used for ASTM A568. 
    • Specimen Size: Hot-rolled sheets should be 0.027 to 0.230 inches in thickness. Cold-rolled sheets should be 0.142 inches in thickness.

    ASTM A568 Result and Interpretation

    ASTM A568 offers detailed rules regulating the overall specifications for coil and cut lengths of steel sheets. It functions as a foundational document that outlines the fundamental standards that apply to different kinds of steel sheet goods. Through the establishment of comprehensive guidelines for steel sheets, ASTM A568 guarantees consistency and uniformity in the production, handling, and application of these materials in a range of industries and uses.
