The inventory of elongation of nm500 material decreased

As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of elongation of NM500 material steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

Large-thickness elongation of NM500 material, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

Our company is a large elongation of NM500 material steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special elongation of NM500 material steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

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 elongation of NM500 material, an increase of 1% over the same period last year.
