S460QL1 steel equivalent sheet properties and usage

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of S460QL1 steel equivalent, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

High quality structural steel thick plate product S460QL1 steel equivalent dimension(mm): 40*2300*12000, 50*1780*7000, 16*2300*12000, 50*2500*10120, 55*1800*11900, 25*2300*12000, 50*2500*10060, 60*2500*8400, 60*2100*10000, 80*1920*6000, 130*2200*10000, 140*2200*10000, 55*1800*11550, 110*2320*8100, 40*1900*7350, 150*2200*10000, 45*2200*9000, 60*2500*8300, 40*2300*12000, 90*2440*12400, 125*1920*5000.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of S460QL1 steel equivalent welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

The data shows that Southeast Asia is the main S460QL1 steel equivalent and so on steel export region of China, and the steel export volume of Asia in 2019 is 37.198 million tons; that of North America and South America is 4.0678 million tons, and that of Europe is 1.1358 million tons. According to the latest epidemic data, South Korea and Japan are the most affected countries in Southeast Asia. However, the growth rate of the number of confirmed cases slowed down significantly, while the situation of the epidemic in Italy, a major European steel export country, was still severe, with the number of confirmed cases exceeding 53000. Therefore, the recovery speed of European market is slower than that of Southeast Asia.
