Technical Specifications
Product Overview
Metallurgical Characteristics
EH32 steel features a fine-grained ferritic-pearlitic microstructure achieved through controlled thermomechanical processing. The steel's enhanced strength is derived from grain refinement, solid solution strengthening, and controlled precipitation of microalloying elements such as niobium and vanadium.
Heat Treatment Process
MetalZenith employs advanced controlled rolling techniques followed by accelerated cooling to achieve optimal mechanical properties. The steel is typically supplied in the normalized or thermomechanically controlled processed (TMCP) condition, with finishing temperatures between 850-950°C and controlled cooling rates to ensure proper microstructural development.
Manufacturing Process
Our EH32 steel production utilizes electric arc furnace melting with secondary refining processes including ladle furnace treatment and vacuum degassing. The steel undergoes continuous casting followed by controlled rolling in our state-of-the-art hot strip mill with precise temperature control and accelerated cooling systems.
Quality Standards & Testing
Every batch of EH32 steel undergoes comprehensive testing including chemical analysis, tensile testing, impact testing at specified temperatures, hardness measurement, and ultrasonic inspection. MetalZenith maintains ISO 9001:2015 certification and follows marine classification society requirements for material traceability and quality documentation.
Weldability & Fabrication
EH32 steel exhibits excellent weldability with carbon equivalent values typically below 0.40%. The steel can be welded using conventional arc welding processes including SMAW, GMAW, and SAW. Preheating may be required for thick sections, typically 100-150°C depending on thickness and ambient conditions.
