Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. , Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace The smelting process is Ca-treated, and should be intrinsically fine-grained steel The actual grain size is 5 or above,PVQ A387 grade 12 class 1 boiler steel plate.PVQ A387 grade 12 class 1 boiler steel plate,The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel products and wholehearted service The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness,PVQ A387 grade 12 class 1 boiler steel plate.PVQ A387 grade 12 class 1 boiler steel plate,Non-destructive flaw detection of steel plates is a test method for inspecting the surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.PVQ A387 grade 12 class 1 boiler steel plate,The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
