As a bulk commodity, the rise and fall of ABS grade B hull structural steel coil, steel pipe prices are related to many downstream industries, such as construction industry, railway, highway, urban public transport and other infrastructure construction, industry and real estate. The price of ABS grade B hull structural steel coil, steel pipe rises and falls every day, and is guided by the quotation market in various places. However, in fact, the procurement of steel pipes is more complicated than this, and the market guide price can only be used as a reference.
15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel ABS grade B hull structural steel coil is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.
With the increase of temperature, the yield limit of ABS grade B hull structural steel coil will decrease monotonically, but the tensile strength of ABS grade B hull structural steel coil will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of ABS grade B hull structural steel coil. Near the blue brittleness temperature, the ABS grade B hull structural steel coil strength increases and the plasticity decreases. The elongation and section shrinkage of ABS grade B hull structural steel coil increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, ABS grade B hull structural steel coil. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
The company has sufficient stocks and complete specifications.
