Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and S275 mild steel resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, S275 mild steel new materials, and promotes the competition of enterprises Struggle.
With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S275 mild steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S275 mild steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
We exported 2150 Tons SG295 steel coils to Sudan. The Sudan customer is LPG cylinder manufacturer. Before our cooperation, he usually purchased SG295 steel coils from UAE and Turkey. And he got to know our company through our regular customers in Uganda, UAE, and his friends in China. Then he gave us the order. We invited the customer to visit us before contract, but he insisted to visit us when the S275 mild steel goods are finished production. After inspecting the size, package in workshop and witness the lab test for the SG295 steel coils, the customer was very satisfied to our quality control and professional arrangement.
