The Indian iron and S900MC cold rolled oil exporting 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 S900MC cold rolled oil exporting decline was 7.7%, about 8 million tons. " Isa said.
S900MC cold rolled oil exporting, Hardened wear-resistant plate refers to the low-alloy steel plate that is hardened by quenching during the rolling process or the low-alloy steel plate is heat treated and hardened. The hardness is generally HB350-500. The wear-resistant layer of the bimetal wear-resistant plate is of high alloy composition. There are a large number of high-hardness alloy carbides (about HV1600) embedded in the matrix in the metallographic structure, which are the main carbides that play a role in anti-wear. The actual micro hardness of the wear-resistant layer is much higher than the measured macro hardness, and its strengthening method is the same as that of cemented carbide.
S900MC cold rolled oil exporting, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.
