ASME SA516 Grade 70 pressure vessel plate is killed steel, when thickness is 40mm or less, the steel plate will deliver in as rolled condition. If customer ask for normalizing, stress relief, or both normalizing and stress relief, it is acceptable. When the thickness of steel plate large than 40mm, normalizing is necessary.
There are various machining service like welding , cutting, milling, drilling for
SA516 Grade 70 different shapes and steel sizes. We have kinds of processing machine to fulfill customers different needs, such as CNC floor-type sharp boring machine, CNC gantry milling, cross submerged arc welding machine, On roller universal three roller plate bending machine, Grinding ring machine, flame cutting machine, 5000 tons pressing machine, 1000 tons of four-column hydraulic machine, 5 m x 10 m large heat treatment furnace, and so on. We can produce oil gas storage, reaction container, and do x-ray inspection and heat treatment for them.
