What is equivalent material of 15MnNiDR steel mechanical properties

In today's 15MnNiDR steel mechanical properties steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of 15MnNiDR steel mechanical properties market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

The effect of nitrogen (N) on the properties of 15MnNiDR steel mechanical properties and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in 15MnNiDR steel mechanical properties and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

15MnNiDR steel mechanical properties, 13MnNiMoR plate flaw detection and thickness direction performance:13MnNiMoR plate can be produced with additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) requirements. The 15MnNiDR steel mechanical properties, 13MnNiMoR plates can be tested one by one by ultrasonic testing. The testing method is in accordance with the provisions of GB / T2970 or JB / T4730.3. The testing standard and qualification level shall be indicated in the contract.

The spot price of hot rolling steel rose on August 18, with a large overall increase. The average price of major cities in China is 3624 yuan / ton, up 95 yuan from last Friday. Shanghai 3520-3540 yuan / ton increased by 70 yuan, Tianjin 3600-3620 yuan / ton increased by 150 yuan, and Lecong 3650-3660 yuan / ton increased by 150 yuan. Central and southern China, North China and Northeast China rose by 90-150 yuan, while Western China rose by 30-60 yuan. The rise in spot 15MnNiDR steel mechanical properties prices led to a significant increase in transactions across the region. Hot rolled futures remained at a high level after opening up and closed at 3440, up 75 2.23%.
