Welcome to BBN High Strength Steels Factory
The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition S460QL1 steel tubing weight is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).
The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product S460QL1 steel tubing weight more than 15 years.
Myanmar's demand for S460QL1 steel tubing weight steel products is likely to exceed 3 million tons in 2020 and 5 million tons by 2025, according to seaisi. However, Myanmar's producers are unable to meet domestic demand, so the country's steel products are more dependent on imports. In 2019, Myanmar imported more than 1.9 million tons of S460QL1 steel tubing weight finished steel, including 57% of long products, 13% of uncoated hot-rolled and cold-rolled flat products, and 30% of coated steel. In order to reduce its dependence on imports, Myanmar plans to increase its steel production capacity by building and expanding steel mills.
According to a report by yonhap news agency on April 26, under the impact of COVID - 19 epidemic, the steel industry chain was also affected. Hyundai lost 29.7 billion won. According to the report, the automobile and other downstream steel industry production stoppage directly led to a precipita-like decline in steel demand, is the main reason for the decline in steel enterprise performance of the main reason for hyundai said, hyundai kia motor production extension, by the end of April is expected to reduce production of 500,000 vehicles, as a result, S460QL1 steel tubing weight, automotive steel demand will be reduced by 300,000 tons.
