In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Our company supply low-alloy high-strength structural steel common grades below: Q345B / C / D / E, A572Grade 50 sheet, A572Gr55 plate, A514 grade B material, A709 Grade 50 steel The company can provide low alloy structural steel plate thickness range of 6 ~ 200mm Our low-alloy high-strength steel is widely used in various types of engineering structures such as steel structure construction, construction machinery, mining machinery, heavy vehicles, bridges, pressure vessels,A514 grade Q structural steel.
Accept the inquiry from the owner of the goods and the inquiry by sea: master the port and price from the port of shipment to all continents and routes, and the port and price that the owner often needs to serve; the shipping schedule information of the main shipping companies; when necessary, ask the owner of the inquiry for some category information, such as the name of the goods, the level of danger, etc. (water hazard code).
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the weathering steel is purified and the content of inclusions is greatly reduced.
A514 grade Q structural steel,Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.A514 grade Q structural steel
Since 2020, the foreign trade industry has been significantly affected by the epidemic. In the first two months of this year, China's steel exports totaled 7.811 million tons, down 27% year-on-year, the largest decline since March 2018. In terms of steel foreign trade, China is mainly a steel exporting country, with less steel imports. The General Administration of Customs said that the volume of steel imports and exports both fell. According to the data of the General Administration of customs, from January to December 2019, China exported 64.293 million tons of steel products, a year-on-year decrease of 7.3%; and imported 12.304 million tons of steel products, a year-on-year decrease of 6.5%. In addition, steel import and export varieties and regions are relatively concentrated.
