High Strength Sheet Steel, 180 MPa through 700 MPa Yield Strengths
|Publication Date:||1 April 2019|
This standard covers the requirements for continuous cast sheet steel with specified minimum yield strengths from 180 MPa through 700 MPa.
Material Description. This specification applies to uncoated and coated, cold (CR) or hot rolled (HR) bake hardenable (BH) and high strength low alloy (HSLA) substrates. Continuously hot or cold rolled flat products shall be supplied as coils or sheet. Hot rolled flat products are usually supplied in thicknesses > 1.75 mm. These flat products are used for cold forming and for manufacturing of welded tubes. Cold or hot rolled flat products with the appropriate surface type and surface finish are suitable for the application of surface coatings, metallic hot dipping, electrolytic 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.
Symbols. Not applicable.
Applicability. Typical applications include body panels, body structure members, chassis components, reinforcements and bumpers.
