RINA FH40 high tensile steel plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of RINA FH40 high tensile steel plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. RINA FH40 high tensile steel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and RINA FH40 high tensile steel plate steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.
From the perspective of market conditions, today RINA FH40 high tensile steel plate spot prices are operating smoothly, futures are volatile, and market acceptance is average. Merchants have a wait-and-see attitude. Low-price transactions are average, while high-price transactions are poor. Most merchants have daily transactions of 200-300 tons. between. For the market outlook, most merchants adopt the mode of selling more and lowering the warehouse, and are cautious about the later market.
