16MnD5 is a medium carbon quenched and tempered steel with good strength, toughness and hardenability. It can obtain better comprehensive mechanical properties after quenching and tempering. After quality, it has higher fatigue strength and resistance to multiple impacts. Low temperature impact toughness Good, no obvious temper brittleness. astm a242 vs a588 low alloy steel coil product is mainly used to make evaporators, voltage stabilizers, pressure vessels and heads, supporting members, etc. in nuclear power projects

astm a242 vs a588 low alloy steel coil, 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.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The astm a242 vs a588 low alloy steel coil, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
