JIS G 3131-Commercial Hot Rolled SPHC Steels
What is SPHC Steels? SPHC steel is a commercial quality hot rolled steel. SPHC is a material grade and designation defined in JIS G 3131 standard. JIS G 3131 is a Japanese material standard for hot rolled steel. The commercial quality hot rolled steel is a type of steel that can be used commercially for forming purposes that can also include shearing of a metallic sheet.
Bending, shaping, lancing and piercing etc all are common operations that can be done on these steels. When a material grade is specified as hot rolled steel, it means it has been subjected to a manipulative process of hot rolling in which a metal bar is passed through high tension rollers above the re-crystallization temperature of the input metallic material. The roller does not only decrease the thickness of the sheets but also changes the grain structure of the steels.
Dimensional Characteristics 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.
The Chemical Composition of SPHC Steels: JIS G 3131 defines the chemical composition of SPHC steels as under:
Maximum percentage of Carbon (C) is 0.15 percent.
Maximum percentage of Manganese (Mn) is 0.60 percent.
Maximum percentage of Phosphorous (P) is 0.050 percent.
Maximum percentage of Sulphur (S) is 0.050 percent.
Remaining is Iron (Fe) percentage and with few negligible impurities.
Mechanical Properties of SPHC Steels
The tensile strength of the SPHC Steels is 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.
Equivalent Material Grades in Other International Standards: The American Standard for Hot Rolled Materials A 1011/A 1011M-07 CS type A-D Steels
The International Standard for Hot Rolled Materials ISO 3573 2008 HR 1 Steel
Applications of SPHC & Commercial Hot Rolled Steels: SPHC Steels are primarily used in pipe and tube manufacturing. These are also used in various applications of Construction including Ship Plate, Wear Resistant Steel and Container Plate,
SPHC hot rolled steels coils are also consumed in many cold-rolled and galvanized products, for example CR sheets, GI coils, and color plates etc.
These are also extensively used in some of the automotive manufacturing, electric products, vehicles, aviation. Precision, meters, food cans, welding pipe making, C- channel, steel rims, storage rack, motorcycle parts, steel furniture, water heater & coolers, etc. |
