GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, A588 Grade B weather resistant steel plate, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.
We supply 3500 tons SA387GR5CL1 steel plates to Pakistan. The main businesses of the Pakistan customer are manufacturing columns & towers, heat exchanger, waste heat recovery boiler, pressure vessel & reactors, tanks, etc. We arranged SGS test for the SA387GR5CL1 steel plates. The test contents include chemical composition analysis, tensile test, impact test, etc. The test results are satisfied. The Pakistan customer gave good feedback after receiving the SA387GR5CL1 steel plates.
The cold working performance of A588 Grade B weather resistant steel plate and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of A588 Grade B weather resistant steel plate and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
