TMCP is the process of rolling and accelerated cooling (PILAC) to produce high tensile steel without heat treatment, which means by adding small amount of alloy, high strength and superior tenacity are obtained and reduction of carbon equivalents (CEQ) provides better performance in use of welding by the customers.
Classification general steel, high tension steel and TMCP-type high-tension steel, with which heat input high-efficiency welding is possible, have all obtained manufacturing approval from overseas classification societies. This steel is widely used in shipbuilding.
Steel excellent in bending and deep drawing is used in automobile structures.
The Steel for general welding structures, bridges, industrial structures has high weldability and is widely used in machines and construction materials. High tension steel the 60kg class is produced after heat treatment process of quenching & tempering.
Such atmospheric corrosion resistant elements as Cu, Cr, and Ni are added to structural steel to increase both weather and corrosion resistance. This type of steel is classified into coated and non-coated steels.
Steel excellent in machinability and abrasion resistance is used in the production of mechanical parts.
Steel excellent in workability and weldability, and both heat and corrosion resistant, is used for gas ball tanks, LPG tanks, petroleum and liquefied materials storage tanks, and fire power generation boilers.
This steel is used in line pipes that transport petroleum or natural gas in large quantities. Steel proven with extremely low-temperature toughness, hydrogen-induced crack(HIC) resistance and stress-corrosion crack(SSC) resistance is produced in order to cope with the worsening environmental situation stemming from exhaustion of our natural resources.
Steel with lamellar tear resistance is used in oil drilling ships and crude oil production platforms. This type of steel has improved ductility in thickness direction as well as lowtemperature toughness.
Ni is added to this type of steel, giving it excellent lowtemperature toughness and corrosion resistance. This type of steel is used in LNG tanks and liquefied gas storage tanks.
