DIN EN10346 HX340LAD HSLA 50 — COLD ROLLED / HOT ROLLED Steel

DIN EN10346 HX340LAD is a hsla 50 grade cold rolled / hot rolled steel conforming to the other international standards. Under the European standard, this designation is minimum yield strength of 340 MPa, micro-alloyed for structural automotive applications.

DIN EN 10346 HX340LAD is a micro-alloyed structural steel with controlled niobium and titanium additions for fine-grained strengthening, produced under European hot-dip coating standards. This grade offers balanced formability and structural performance for moderately loaded automotive body members, cross-car beams, and underbody reinforcement panels where European OEM specifications govern material selection and testing protocols.

Ameristeel maintains a deep inventory of DIN EN10346 HX340LAD in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled / hot rolled product, DIN EN10346 HX340LAD 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 HX340LAD 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 HX340LAD depends on your forming process, paint system, and end-use corrosion environment.

DIN EN10346 HX340LAD is listed alongside DIN EN10346 HX260LAD and DIN EN10346 HX380LAD within this specification family. As a hsla 50 designation, DIN EN10346 HX340LAD addresses specific cold rolled / hot rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

DIN EN10346 HX340LAD 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 HX340LAD specifications with complete mill test reports and material certification.

Ameristeel offers in-house processing for DIN EN10346 HX340LAD 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. From raw material sourcing through finished part delivery, Ameristeel provides a single-source solution — eliminating the need to coordinate between separate steel suppliers, service centers, and fabrication shops.
