Vanadium is a weak deoxidizer. Adding vanadium into TM rolled GL-AH 40 hull steel plate steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.
Grade AH32/AH36, TM rolled GL-AH 40 hull steel plate, Grade DH32/DH36 high-strength structural steel products for hulls have good comprehensive mechanical properties, welding performance, good processing performance. Grade AH32/AH36 hull strucural steel is suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities, etc. in ocean, coastal and inland navigation areas.
The Indian iron and TM rolled GL-AH 40 hull steel plate Steel Association (ISA) lowered its steel demand forecast for 2020 to 5.1% from 5.1% in February this year. The figure is expected to hit a low of 7.7%. The company said in an official statement that the current share price has fallen sharply due to the huge downside risk. "We expect India's finished steel demand to fall to about 93.7 million tons by 2020, down from 101.5 million tons in 2019." This calendar year, the TM rolled GL-AH 40 hull steel plate decline was 7.7%, about 8 million tons. " Isa said.
According to a statistical study, Iran has decided to produce 33 million tons of steel in its calendar year (from March 20, 2020). A study of the performance of the mining sector affiliated to the mining and mining development and transformation organization of Iran (imidro) in the first month of the year (March 20 to April 20) shows that this month produced 5.4% of the 33 million tons produced at the end of this year. In the first month of this year, relevant enterprises in the country produced about 1797927 tons of steel, including TM rolled GL-AH 40 hull steel plate, an increase of 1% over the same period last year.
