Why there are quality defects on the surfaces of quenched and tempered GL-E40 hull steel plate

BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, quenched and tempered GL-E40 hull steel plate steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, quenched and tempered GL-E40 hull steel plate chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

ASME SA 53 seamless pipe is manufactured according to quenched and tempered GL-E40 hull steel plate ASME code. Because it belongs to low carbon steel, the surface hardness can only be improved by carburizing. If you are interested in BBN quenched and tempered GL-E40 hull steel plate ASTM A53 or ASME SA 53 carbon seamless pipe, please contact us for the latest price.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of quenched and tempered GL-E40 hull steel plate metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, quenched and tempered GL-E40 hull steel plate.
