SAE J2340 380X HSLA 55 — COLD ROLLED / HOT ROLLED Steel

SAE J2340 380X is a hsla 55 grade cold rolled / hot rolled steel conforming to the sae standards. At 380 MPa minimum yield strength, this is high-strength steel for front-end structure components, rocker inners, and A-pillar reinforcements.

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

SAE J2340 380X represents the mid-tier solution-hardened HSLA designation within the J2340 standard, engineered with micro-alloying additions for grain refinement and precipitation strengthening. At this strength level, the 380X grade balances formability with structural performance for front-end module brackets, seat track reinforcements, and suspension tower gussets where controlled stretch flanging is required during stamping operations.

Ameristeel maintains inventory of SAE J2340 380X 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 380X include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

SAE J2340 380X at 380 MPa yield compares to SAE J2340 340X (40 MPa higher yield at 340 MPa) and SAE J2340 420X (40 MPa lower yield at 420 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
