For decades, IBC (Tianjin) Industrial Co..Ltd has manufactured JIS G3131 SPHC steel. SPHC hot rolled steel plate under standard JIS G3131 is primarily used for stamping and forming. Steel plates designated as SPHC, SPHD, SPHE and SPHF by the Japanese Industrial Standards. In addition to widely used in the manufacture of pipes and tubes, this steel is also used in numerous construction applications, including ship plates, wear-resistant steels and container plates.

What is JIS G3131 SPHC Steels?

The Japanese hot roll steel standard JIS G3131 specifies technical requirements for mild steel sheets, sheets, and strips. SPHC is its material grade and designation; it is a commercial grade hot rolled steel that used in sheet metal as well as forming. Due to its high strength, SM570 Steel is also a hot roll steel, but it is intended for use in welded structures.

Material grades designated as hot rolled steel are those that have undergone a manipulative process of hot rolling in which a metal bar passes through high tension rollers above the temperature at which the input material will re-crystallize. Besides reducing sheet thickness, the roller also alters the grain structure of the steel.


Dimensional Specs of SPHC Steels

The applicable thickness for this SPHC material as defined in the JIS 3131 starts from 1.2 mm to 14 mm. However the width of SPHC material ranges to 2000 mm. We can supply many specifications of SPHC steel structure based on the customer’s requirement.

Chemical Composition of SPHC Steels

JIS G3131 SPHC hot rolled steel plate is stamping and forming steels. JIS G 3131 defines the chemical composition of SPHC steels as under:

Symbol of GradeCMnPS
SPHC0.15 max.0.60 max.0.050 max.0.050 max.

Mechanical Properties of SPHC Steels

The tensile strength of the SPHC Steels expressed in Newton per millimeters and it must be at least 270 N/mm2 (MPa). The elongation property of SPHC steel varies with the ranges of thickness.  The minimum percentage ranges for elongation is from 27 to 31 percent starting from 1.2 mm to 4 mm and over.

Applications of SPHC & Commercial Hot Rolled Steels

The SPHC steel commonly used to produce tubes, pipes, and ship plates, as well as wear-resistant steels and container plates. They can also found in many other manufactured goods, including color plates, CR sheets and GI coils. Additionally, they widely used in automobile manufacturing, electric devices, and aviation equipment.

Moreover, these steels can further be harnessed for the manufacture of food cans, welding pipes, C-channels, steel rims, storage racks and motorcycle components. Finally, SPHC product can also use to make steel furniture like water heaters and coolers.
