US best api 5l psl2 x70 steel quality imports increase by 8.9%
The characteristic of niobium in best api 5l PSL2 x70 steel quality etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). best api 5l PSL2 x70 steel quality. Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
High quality pipeline steel plate is the key material for ERW line pipe, LSAW line pipe and best api 5l PSL2 x70 steel quality SSAW line pipe. It is widely used in oil, natural gas and water transportation pipeline construction, and can be used for manufacturing pressure fluid transportation construction.
