The Cr-Mo alloy steel pipe fittings manufactured to ASTM A234 includes the grades of WP1, WP12 CL1, WP12 CL2, WP11 CL1, WP11 CL2, WP11 CL3, WP22 CL1, WP22 CL3, WP24, WP5 CL1, WP5 CL3, WP9 CL1, WP9 CL3, WP91, WP911, WP92. The BW pipe A572 Gr 55 CS steel carbon plate fittings can be made from either seamless pipes, or fusion-welded pipes which shall be with filler metal added and shall conform to the chemical requirements of the standard specification.
Advantages of A572 Gr 55 CS steel carbon plate, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.
In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like A572 Gr 55 CS steel carbon plate, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate A572 Gr 55 CS steel carbon plate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
