Supplied Forms

Grade 409 / 1.4512 is a rolled product (sheet, coil and strip) material usually available up to a maximum of 2.5mm thickness.
Grade 1.4003 is similar though not a direct equivalent but is available in thicker sheets and plates.

  • Sheet


Weldability of grade 409 is good up to about 2.5mm thick. 

If welding of thicker material is necessary, then grade 1.4003 should be selected.
