Grade 91 Steel - an overview ScienceDirect Topics

The representatives of conventional ferritic-martensitic steels are the creep strength enhanced ferritic steels which include 912% Cr steels such as ASME Grade 91, 92, and 122, X10CrMoVNb9-1 (1.4903), or Modified 9Cr-1Mo steel. The elevated temperature properties of those materials depend on heat treatment conditions. Influence of microstructure on cavitation in the heat Dec 01, 2020 · In the present research, a systematic investigation has been conducted after long-term creep exposure in the heat affected zone of a multi-pass weld on the 9% Cr Grade 92 steel to identify the sub-optimal microstructures with a high susceptibility to creep cavitation.

Toughness and Steel Creep Rupture Strength of Grade 92

The creep rupture data, for all-weld-metal creep specimens, are presented in Figure 8, together with data from ECCC data sheets for grade 92 parent steel and data for 92 grade Thermanit 616 submerged arc welds. [6,5] Several of the present welds gave actual or extrapolated 10,000h rupture stresses of ~150MPa, which is similar to the creep rupture strength of the 92 grade parent steel. Grade 92 creep-strength-enhanced ferritic steel Jan 01, 2014 · Ferritic creep-resistant steel, according to ASME Code case Grade 92 (Gr.92), contains 9%Cr (chromium). It has a high creep rupture strength at 600°C for 100 000 h, and is therefore a suitable material for long-term use in a high-temperature and pressure steam circulating coal-fired power plant.
