SPHE steels are deep drawing quality hot rolled steels. SPHE steel is a material grade and designation defined in JIS G3131 standard. It also lies in the category of dead mild steel. For more related information examine SPHD & SPHC steels, since there is a slight difference of chemical composition between SPHE & SPHD & SPHC steels so as to ensure even better mechanical properties in SPHE steels than SPHC & SPHD steels.
SPHE steel plate/sheet is in JIS G 3131 standard. It's grade Number is 1.0398.
JIS G3131 SPHE steel is mainly used as stamping and cold forming steels. It is used for non-structural presswork and forming
SPHE Steel Chemical Composition :
SPHE steels are composed of following chemicals with given proportion.
Carbon is less than or equal to 0.10%.
Manganese is less than or equal to 0.5 %.
Maximum range of Phosphorous & Sulphur is 0.03 & 0.035 %.
Rest percentage is of iron in the chemical composition of SPHE steels.
SPHE Steel Mechanical Properties :
The tensile strength of SPHE grade is same as of SPHC steel grade i.e. at-least 270 N/mm2 (MPa). The elongation of this grade is different for different ranges of thicknesses. Looking at the lower tolerable elongation for the lower gauge of 1.2 to 1.6 mm is 31 % minimum. The bend-ability of material is 180 degrees on itself.
