JAH400W Low Carbon — Hot Rolled Steel

JAH400W is a low carbon grade hot rolled steel conforming to the other international standards. JAH400W is a hot rolled product with a base tensile strength of 400 MPa. The "W" suffix designates structural quality with 400 MPa minimum yield strength for load-bearing applications, defining specific elongation and mechanical property requirements under the JIS G 3302 / G 3313 family.

Ameristeel maintains inventory of JAH400W 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 JAH400W include Galvannealed, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

JAH400W is listed alongside JAH370W and JAH440W within this specification family. As a low carbon designation, JAH400W addresses specific hot rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.
