DIN EN10346 HX380LAD HSLA 55 — COLD ROLLED / HOT ROLLED Steel

DIN EN10346 HX380LAD is a hsla 55 grade cold rolled / hot rolled steel conforming to the other international standards. Under the European standard, this designation is minimum yield strength of 380 MPa, micro-alloyed for structural automotive applications.

DIN EN 10346 HX380LAD delivers higher structural capacity than HX340LAD through increased micro-alloy precipitation and controlled rolling practices, meeting European hot-dip coated steel standards. This grade targets higher-stress chassis and body applications including longitudinal tunnel reinforcements, rear floor cross-members, and suspension mounting interfaces where European specification compliance and weldability to coated substrates are essential design requirements.

Ameristeel maintains a deep inventory of DIN EN10346 HX380LAD in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled / hot rolled product, DIN EN10346 HX380LAD offers the tight thickness tolerances and controlled surface finish critical for visible and semi-exposed automotive applications. Every coil is third-party tested under our ISO 9001:2015 quality system.

DIN EN10346 HX380LAD is supplied with the following coating options: hot-dip galvanized (zinc) for general corrosion resistance; galvanneal (zinc-iron alloy) for superior paint adhesion and weldability; aluminized for high-temperature oxidation resistance. The right coating choice for DIN EN10346 HX380LAD depends on your forming process, paint system, and end-use corrosion environment.

DIN EN10346 HX380LAD is listed alongside DIN EN10346 HX340LAD and DIN EN10346 HX420LAD within this specification family. As a hsla 55 designation, DIN EN10346 HX380LAD addresses specific cold rolled / hot rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

DIN EN10346 HX380LAD is widely used across structural construction, heavy equipment manufacturing, pressure vessel fabrication, bridge and infrastructure components, and automotive chassis applications. Ameristeel sources and stocks this grade at our Fraser, MI steel processing center, with the ability to supply production quantities, prototype runs, and custom-processed orders. Whether you need full coils, slit-to-width coils, cut-to-length sheets, or precision blanks, our team can fulfill orders to DIN EN10346 HX380LAD specifications with complete mill test reports and material certification.

Ameristeel offers in-house processing for DIN EN10346 HX380LAD at our Warren and Fraser, Michigan facilities. Available processing capabilities include precision slitting to custom widths on our multi-cut blanking line, cut-to-length sheet processing for exact dimensional requirements, laser cutting of high-strength profiles on our TRUMPF fiber laser with up to 4kW power, press brake forming on our TruBend series with up to 110-ton capacity and 120" bend length, shear processing for rapid sheet production.
