ASME SA 53 seamless pipe is manufactured according to A633 Grade D mild steel ASME code. Because it belongs to low carbon steel, the surface hardness can only be improved by carburizing. If you are interested in BBN A633 Grade D mild steel ASTM A53 or ASME SA 53 carbon seamless pipe, please contact us for the latest price.
A633 Grade D mild steel, Q345D seamless pipe is low-alloy high-strength structural steel. It is named as low-alloy because of a small amount of alloy elements in the steel. Q345D seamless pipe is mainly used for construction and engineering structures. The carbon content of Q345D seamless pipe is ≤ 0.18%. Due to the effect of alloy elements, the yield strength of Q345D seamless pipe is 25% - 150% higher than that of carbon structural steel pipe with the same carbon content. Q345D seamless pipe can reduce the weight of steel structure, save steel products and effectively extend the service life of steel structure.
The effect of elements in A633 Grade D mild steel, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.
