Hot Rolled Coil (HRC).
Hot Rolled Coil (HRC) is a steel product in form of coiled steel strip produced from hot rolling process in Hot Strip Mill facility. This product is often called as “black steel” by the users to distinguish this product with cold-rolled product which is often called as “white steel”. Our products complying to both international and national product quality standards. The steel slab as the raw material is reheated up to 1,200 °C then further rolled until achieving the final desired thick- ness. The cooling mechanism is combining both forced laminar water cooling prior to coiling process and air cooling in the product storage area.
Application : General & Welded Structure, Rerolling, Oil & Gas Pipe, Automotive, Pipe & Tube, Container, Ship Building, Heavy Duty Vehicle, Weathering & Corrosion Resistant Steel, Boiler & Pressure Vessels.
JIS G3131 SPHC Material Properties
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.
JIS G3106 SS-400 Material Properties
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 A36 Material Properties
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.
ASTM A283 Grade C Material Properties
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.
ASTM A516 Grade 70 Material Properties
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.
