What is SAPH440 Steels? SAPH440 steel is a structural Hot Rolled steel in the form of plates, sheets & strips for automobile structural applications. SAPH440 is a material grade and designation defined in JIS G 3113 standard. JIS G 3113 is a Japanese material standard for Hot Rolled steel plates, sheets, strips for automobile structural usage. The structural quality hot rolled SAPH440 steel is more reliable in its tensile strength than SAPH400 steel. It can be used in automobile applications where more strength is needed & the material does not fail under exceeding loading.
Dimensional Characteristics of SAPH440 Steels: The applicable thickness for this SAPH440 material as defined in the JIS 3113 starts from 2 mm to 14 mm. However the width of SAPH440 material ranges to 950 to 2000 mm.
he Chemical Composition of SAPH440 Steels: JIS G3113 defines the chemical composition of SAPH440 steels as under:
Carbon (C) is not identified in the standard.
Manganese (Mn) is not identified in the standard.
Maximum percentage of Phosphorous (P) is 0.040 percent.
Maximum percentage of Sulphur (S) is 0.040 percent.
Remaining is iron (Fe) percentage and with few negligible impurities.
