45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of RINA AH36 offshore oil drilling platform steel, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.
RINA AH36 offshore oil drilling platform steel, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the RINA AH36 offshore oil drilling platform steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between RINA AH36 offshore oil drilling platform steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM. EN10113 S275M steel plate/sheet,EN10113 S275M steel plate/sheet, under EN standard, we can regard RINA AH36 offshore oil drilling platform steel, S275M steel plate/sheet for Fine-grain structural steels, thermomechanically rolled steel.
