SAE J2340 550X HSLA 80 — COLD ROLLED / HOT ROLLED Steel

SAE J2340 550X is a hsla 80 grade cold rolled / hot rolled steel conforming to the sae standards. At 550 MPa minimum yield strength, this is ultra-high-strength steel for door intrusion beams, bumper reinforcements, and tunnel structures.

The X suffix denotes solution-hardened (micro-alloyed) HSLA steel with niobium, vanadium, or titanium additions for grain refinement and precipitation strengthening.

Ameristeel maintains inventory of SAE J2340 550X in various gauges and widths, available as coils, sheets, or custom blanks. Our ISO 9001:2015 certified processes ensure consistent quality from prototype through production volumes.

Available coating options for SAE J2340 550X include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

SAE J2340 550X at 550 MPa yield compares to SAE J2340 490X (60 MPa higher yield at 490 MPa) and SAE J2340 420X (130 MPa higher yield at 420 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
