Hot Rolled Coil (HRC)

JIS SPHC steel is a commercial quality hot rolled steel. 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.

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.

SPHC Steel Mechanical Properties

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.

SS400 according to material grade and name defined in the JIS G 3101 standard, The first S stands for "Steel", the second S stands for "Structure", and 400 for the lower limit tensile strength of 400 MPa. Ordinary structural steel with a tensile strength of 400 Mpa.This steel is the most widely used in JIS standard. Its use covers structures such as bridges, ships, vehicles, etc., in the shape of steel plates, steel bars and sections, almost all auxiliary materials for machinery and structures are used.

SS400 is also soft in hardness due to its low carbon content. It is not recommended for use on main components with high strength, wear resistance or hardness. However, it has excellent weldability and machinability. It is often used for welding structural parts, nuts, small parts, parts for auto & motor industry, etc.

ASTM A 36 is A low-carbon steel with excellent fabrication properties. This grade is commonly utilized for general fabrication and structural purposes such as steel building components. It covers carbon steel plate, shape, and bar of structural quality for use in riveted, bolted or welded construction of bridges and building and for general structural purpose.

The ASTM A283 is a structural carbon steel plate utilized for applications requiring low or intermediate tensile strength. This grade is used in the manufacture of storage tanks and low pressure, temperature controlled vessels.

The ASTM A516 is a carbon steel plate grade utilized primarily in welded pressure vessels for moderate to lower temperature service. This material is produced in grades 55, 60, 65 and 70. This material is also offered in the normalized condition where improved notch toughness is required.
