It is a modern high-tech professional enterprise integrating scientific research, production and sales.
API 5L is a specification for pipeline steel pipe formulated by the American Petroleum Institute. The main steel grades in API 5L are: A, B, X42, X46, X52, X56, X60, X65, X70, X80, X90, X100, X120, etc. In API standard, pipeline steels are divided into PSL1 and PSL2. In the standard, there are slight differences in chemical composition, A588 grade B HSLA steel plate mechanical properties, inspection items, acceptance standards, delivery status, etc between PSL1 and PSL2 steel. For example, API 5L PSL1 X42 requires an upper carbon limit of 0.26, while API 5L PSL2 X42 requires an upper carbon limit of 0.24.
Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. A588 grade B HSLA steel plate, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.
The allowable temperature of A588 grade B HSLA steel plate, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of A588 grade B HSLA steel plate work, the actual stress of A588 grade B HSLA steel plate under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of A588 grade B HSLA steel plate under the temperature.
A588 grade B HSLA steel plate, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
