Steels with intermediate to high carbon contents and high levels of other alloying elements exhibit excellent formability and structural integrity, allowing them to be shaped into a wide range of steel profiles and sections. These may be treated and tested to a variety of specifications for rigorous building demands and are often found in a variety of engineering applications across the world.
Masteel provides structural carbon steels in various specifications, including S355, which has a minimum yield strength of 355 N/mm²m.
HIC (hydrogen induced cracking) resistant carbon steel is ultra-low carbon steel that is commonly utilized in the oil and gas industry for sour service. Steel components in near-constant contact with hydrogen sulfide may develop hydrogen embrittlement and associated cracking over time. This is a costly, time-consuming, and sometimes dangerous sign of sour service that may be avoided by employing HIC resistant carbon steel. HIC resistant carbon steel is desulphurized and dephosphorized to remove unwanted trace elements and provide a wonderfully pure homogeneous steel with less than 0.2% carbon content.
Masteel provides a variety of HIC-resistant steel grades, including MASTERHIC 5, MASTERHIC 10, and MASTERHIC 15.
Flat-rolled sheets of low-carbon steel and high formability mild steel are utilized in the production of several lightweight and high-hardness constructions. Deck facilities on ships of varying sizes commonly employ carbon steel to complement the heavier, corrosion-resistant hull plating, which typically contains a greater manganese concentration.
Steels of various grades are utilized in the construction of ship superstructures, with low and mild carbon steels serving as a foundation for harder steel cladding. Those with manganese concentrations as high as 1.65% are routinely produced into steel plates and surface treated to withstand a variety of corrosive substances. These products are commonly utilized to construct the hulls and superstructures of container ships and passenger liners.
Masteel provides a variety of shipbuilding carbon steel grades, including AH36, DH36, and EH36.
The gas and petrochemical industries are among the most significant users of raw carbon steel materials, producing millions of miles of carbon steel pipework and pressure vessels. Low-carbon steel is an intriguing option for these uses due to its high weldability for forming into complicated, rounded forms and its case hardening capabilities.
Case hardening, also known as carburization, is a treatment process that encourages carbon migration to the steel’s exterior. Carburization protects the solid and ductile inner core while forming a high-hardness crust on the vessel’s or pipe’s exterior to defend against various weathering factors.
Masteel provides many pressure vessel steel grades that are certified to ASME SA285 and several foreign standards.
Carbon steel accounts for the vast majority of steel types produced and accessible on the worldwide market today. Like every other form of steel, carbon steel has unique properties, advantages, and disadvantages.
