The boiler steel plate is used to manufacture various boilers and important accessories. Because the LR grade A passage ship steel boiler steel plate works under the medium temperature (below 350 ° C) and high pressure state, it is not only subject to high pressure, but also to impact, fatigue load and water and air corrosion. The boiler steel plate is required to ensure certain strength and good welding and cold bending performance.Bridge steel plate LR grade A passage ship steel is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.
What are the general uses of LR grade A passage ship steel, low alloy steel plate? First, low alloy steel plate can be used as bridge steel plate, because it has strong bearing capacity. The bridge’s daily traffic flow is very large, so it must have very good bearing capacity. Second, because low alloy steel plate has good toughness and is easy to process, it is often used to manufacture ships and vehicles. Thirdly, the use of low alloy steel plate is indispensable to the construction of some frame structure workshops. Because of the low alloy content, low alloy steel plate has its own characteristics.
Tempering the important LR grade A passage ship steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve LR grade A passage ship steel strength, plasticity and toughness.
"High strength low alloy steel plate pecifications: LR grade A passage ship steel, A516 Grade 60 plates and sheets are producted with thickness up to 200mm [8 inch].A516 Grade 60/70 Dual Certified HIC NACE TM0284 Plates Hydrogen Induced Cracking;Hot Rolled Steel ASTM A516 Grade 60 Dual Certified HIC Tested Plates in accordance with Nace Test Method, ASTM A516 70 HIC Tested (Hydrogen Induced);Tested Fine Grained Pressure Vessel Steel Plates For Sour Gas Service."
