Manufacturer directly supply RINA FH40 hull steel plates price per ton

Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel RINA FH40 hull steel plates products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with RINA FH40 hull steel plates good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.Try to use RINA FH40 hull steel plates high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the RINA FH40 hull steel plates temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.With the increase of temperature, the yield limit of RINA FH40 hull steel plates will decrease monotonically, but the tensile strength of RINA FH40 hull steel plates will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of RINA FH40 hull steel plates. Near the blue brittleness temperature, the RINA FH40 hull steel plates strength increases and the plasticity decreases. The elongation and section shrinkage of RINA FH40 hull steel plates increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
