Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often ＜0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate A514 Gr Q quenched and tempered steel has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.
The advantages of A514 Gr Q quenched and tempered steel, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
India began to implement the national blockade measures on March 25. After two extensions, the national blockade measures have been implemented for nearly 50 days, which has a huge impact on the A514 Gr Q quenched and tempered steel economy. To that end, modi said in a televised speech on the evening of the 12th that India will launch a total of 20 trillion Indian rupees one point eight eight Trillion yuan).
According to A514 Gr Q quenched and tempered steel traders in some regions, the downstream purchasing sentiment is maintained, the inventory resources are relatively small, and the A514 Gr Q quenched and tempered steel traders are more willing to strike a deal; in addition, the domestic steel mills have issued guidance prices recently, and the long-term upward range is large, which has a boosting effect on the market. In addition, there are A514 Gr Q quenched and tempered steel production line maintenance at the end of the month, so the supply side is tight. Overall, the short-term forecast for A514 Gr Q quenched and tempered steel will fluctuate mainly upwards tomorrow.
