SPHE is under the standard of JIS G3131 carbon low alloy steel, SPHE belongs to typical high hardness, high toughness and high strength steel, with the yield strength of 270 mpa. SPHE steel is used to make more H - beam, I - beam, channel building profiles, such as auto parts, and cold extrusion mould, etc.

SPHE features:
1, reduce costs, instead of cold-rolled plate pickling plate, cost savings for the enterprise.
2, good surface quality, compared with ordinary hot-rolled plate, hot-rolled pickled plate removes surface scale, improve the surface quality of steel, easy welding, oiled and painted.
3, high dimensional accuracy, after formation, can make certain changes occur plate, thereby reducing unevenness deviation.
4, to improve the surface finish and enhanced appearance.

SPHE steel application:
SPHE has high strength, good toughness, easy processing molding and good weldability and excellent performance, which is widely used in the automotive industry, machinery industry (excluding motor vehicles) including textile machinery, mining machinery, general machinery as well as some fans, light industrial electronics, bicycle parts, all kinds of pipe, electrical cabinets, highway guardrail, supermarket shelves, storage shelves, fence, iron ladder and stamping parts of various shapes.
