Low alloy steel plate was originally developed for large diameter oil and gas pipeline in 1960s. Pipeline steel materials used in oil and gas projects require higher strength and toughness than low carbon steel, and have good weldability just the same as low carbon steel.Advantages: A131 EH40 ship steel plate, Low alloy steel plate has superior performance and light weight.Disadvantages: Low alloy steel plate is killed steel, so the price will be more expensive.
4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. A131 EH40 ship steel plate, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.
The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by A131 EH40 ship steel plate metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the A131 EH40 ship steel plate steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
