Performance & Metallurgical Characteristics
Produced via controlled quenching and tempering to achieve a 100 ksi (690 MPa) minimum yield strength, allowing thinner plate designs for heavy-load equipment.
Formulated with optimized alloying to maintain Charpy V-notch impact toughness at temperatures down to -40 °C.
Maintained at controlled carbon equivalent (CEV) levels to support standard welding methods like SAW and SMAW with appropriate preheating protocols.
Refined through secondary ladle processing (LF+VD/RH) to reduce steel impurities and ensure consistent mechanical properties across each plate.
Typical Applications
Pressure Vessels & Boilers: Storage spheres, liquefied gas tanks, and high-pressure reactors.
Energy & Offshore: Hydroelectric penstocks, offshore platform structural components, and subsea structures.
Heavy Equipment: Mining truck bodies, crane booms, and heavy transport chassis requiring high payload-to-weight ratios.
