This specification covers the requirements for continuous cast sheet steel with specified minimum yield strengths from 180 MPa through 550 MPa applicable to uncoated and coated, cold or hot rolled low carbon, solid solution strengthened, bake-hardenable, high strength low alloy, or dual phase substrates with good formability. Continuously hot or cold rolled flat products shall be supplied as coils or sheet. Hot rolled flat products are usually supplied in thicknesses greater than 1.75 mm. These flat products are used for cold forming and for manufacturing of welded tubes. Cold rolled flat products with the appropriate surface type and surface finish are suitable for the application of surface coatings (metallic hot dipping, electrolytical plating, hot spray painting, organic coatings and/or other coatings). This specification does not apply to steel for case hardening and cold reduced, work hardened strips.
