Export 1000 tons ASTM A514 QT steel plate to Morocco

ASTM A514 QT steel plate,EN10025-2 S235J2 steel is equivalent to our Chinese teel grade Q235D. They are both done low temperature impact test at -20℃. Sometimes S235J2 would be used to built containers which can bear low temperature sea water. , S235J2+N steel plate, following a rolling process within a certain temperature range, producing a material in a condition equivalent to that obtained after normalization. With the result that the specified mechanical properties values are conserved even after normalization treatment.The company has allocated special environmental protection facilities for all pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, steel mill scale, environmental protection dust has reached 100%,ASTM A514 QT steel plate.ASTM A514 QT steel plate,Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
ASTM A514 QT steel plateDue 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.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem,ASTM A514 QT steel plate.
