Why P91 material used for welding procedure?

Aug 22,2017 p91 material composition#0183;Normally,the composition of the welding electrodes used in line with the respective parent material which decides those factors so P91 is perfect for welding.P91 is the major construction material that can be utilized for different applications when it comes to suing this material for welding it is important to apply particular methods for Welding of A217 C12A cast steel to A 335 Grade 91? - ASME C12A is the cast form of grade P91,typically used for thick walled valve bodies,els,tees,wyes,etc.One issue that does not seem to be completely addressed by US codes is that this material needs to be cooled ( or quenched) following N+T such that the rate of cooling is at least -9F/min in the temperature range 2000 to 1200 F,in order to ensure martensite is formed.Welding chromium-molybdenum steel pipe for power plantsFor heavy-wall P91 weldments,that temperature is typically 1,400 p91 material composition#177;25 degrees.Other alloys may be between 1,100 to 1,400 degrees.Soak time depends on the thickness of the material.One hour per inch is common for most alloys,but Newell recommends that heavy-wall (greater than 3/4 in.) P91 components should have a minimum soak time of two hours.
