SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.

15Mo3 steel plate/sheet is one mainly of Steel for boiler steels.DIN 17155 15Mo3 steel is mainly used for boilers and pressure vessels with elevated temperatures which is equivalent to EN10028 16Mo3 and UNI5869 15Mo3, 15D3 (NFA 36205 ) and ASTM A204Gr.B.Q355GNH to GB/T 4171 steel sheet

Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.Q355GNH to GB/T 4171 steel sheet

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness. EN10083-3 42CrMo4 steel plate has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.Q355GNH to GB/T 4171 steel sheet
