ANSWER:JAC440R is a steel grade in Japanese standard JFS A 3011 , it is hot-dip galvannealed steel sheet or strip for automobile use. JAC440R is a generial use quality steel material.The coating of JAC440R is Zinc and Iron alloy. The base material product is cold rolled steel sheet. The “C” in “JAC440R” means cold rolled. The “R” mean high yield ratio.
JAC440R material steel have coil, strip, sheet condition, thickness is from 0.4mm-2.3mm.
JAC440R steel Coil/strip/sheet surface quality:
A (As coated surface), B (Improved surface),C (Best quality surface)
JAC440R steel Coil/strip/sheet surface treatment:
Chemical treated or not chemical treated, Oiled or not oiled, Phosphatized or not Phosphatized.
JAC440R steel Coil/strip/sheet coating mass:
Alloy Zinc+Fe: A01(ZF001), A25(ZF75), A40(ZF120), A60(ZF180)
JAC440R steel yield strength should be 345MPa-470MPa
JAC440R steel tensile strength should be not less than 440MPa
JAC440R steel Elongation should be not less than 22%.
