The invention discloses a 12Cr2Mo1R thick steel plate used in equipment contacting hydrogen and a production method thereof which includes the following steps a) The mass percentage of constituents is as follows C 0.10 to 0.15, Si less than or equal to 0.10, Mn 0.40 to 0.60, P less than or equal to 0.010, S less than or equal to 0.003, Cr 2.0
An investigation of hydrogen embrittlement of With excellent mechanic properties and hydrogen embrittlement (HE) resistance, 12Cr2Mo1R(H) steel is suitable to make hot-wall hydrogenation reactors. However, longtime exposure to a harsh environment of high-pressure hydrogen at medium temperature in practical application would still induce severe hydrogen uptake and eventually damage the mechanical properties of the steel.
GBT713 12Cr1MoVR vessel steel plates have excellent toughness and weldability. When the temperature is below 500 C, 12Cr1MoVR steel plates have high endurance strength. The most often used heat treatment of 12Cr1MoVR vessel steel plates is normalizing and tempering.
