P91 - MODIFIED 9CrMo Alloy type Modified 9CrMo for high temperature creep resistance. Materials to be welded ASTM A 213 T91 (seamless tubes) A 335 P91 (seamless pipes) A 387 Gr 91 (plates) A 182 / A336 F91 (forgings) A 217 C12A (castings) A 234 WP91 A 369 FP91 DIN / BS EN 1.4903 (X10CrMoVNb 9 1) BS 1503 Gr91 3059-2 Gr91 AFNOR NF A-49213/A-49219 Gr TU Z 10 CDVNb 09-01 Applications These consumables are designed to weld equivalent ‘type 91’ 9CrMo steels modified with small additions of niobium, vanadium and nitrogen to give improved long term creep properties. These consumables are specifically intended for high integrity structural service at elevated temperature so the minor alloy additions responsible for its creep strength are kept above the minimum considered necessary to ensure satisfactory performance. In this case, weldments will be weakest in the softened (intercritical) HAZ region of parent material, as indicated by so-called ‘type IV’ failure in transverse weld creep tests. Modified 9CrMo steels are now widely used for components such as headers, main steam piping and turbine casings, in fossil fuelled power generating plants. They may also find future use in oil refineries and coal liquefaction and gasification plants. Microstructure In the PWHT condition the microstructure consists of tempered martensite with alloy carbides.

To ensure full martensite transformation, welds should be cooled to ~100°C prior to PWHT. ASME base material codes and AWS consumable classifications allow PWHT down to 730°C, whilst BS EN consumable classifications specify 750°C. Optimum properties are obtained with a tempering parameter (P) of around 21 or above, where P = °C+273 (log t + 20) x 10 –3 . Maximum PWHT temperature varies, AWS consumable specifications are 760°C, BS EN 770°C; BS 1503 allows up to 790°C for base material forgings. When compared with directly matching weld metal, the addition of some nickel and reduction of niobium provides a useful improvement in toughness after conveniently short PWHT at 750 – 760°C. PWHT above 765°C is not generally recommended for Ni-containing consumables, because some re-hardening could occur due to the proximity of Ac1. Some authorities specify weld metal Ni + Mn < 1.5% to keep Ac1 high enough to allow higher PWHT temperature if required.
