Local Approach : Numerical Simulations of Creep and Creep-Fatigue Crack Initiation and Crack Growth in 316L SPH Austenitic Stainless Steel

An assessment of a creep-fatigue crack growth for Mod. 9Cr-1Mo steel wide plates have been carried out based on an extended French high temperature design code, RCC-MR A16 guide. The defect assessment guide of the A16 provides assessment procedures on creep-fatigue crack growth for an austenitic stainless steel, but no guidelines are available yet for a Mod. 9Cr-1Mo steel. In this study, assessments of a creep-fatigue crack growth at defects of Grade 91 steel wide plates have been carried out based on the extended A16 method for austenitic stainless steel.

Creep Fatigue Crack

Creep-fatigue crack behaviour has been investigated for a welded component with 316L stainless steel and Mod. 9Cr-1Mo steel through an assessment and test. The evaluation of creep-fatigue crack initiation and propagation was carried out for 316L stainless steel according to the French RCC-MR A16 guide, and evaluation on creep-fatigue crack initiation for Mod.9Cr-1Mo steel in a specimen was carried out with an extended A16 method. A test for a structural specimen with a diameter of 500mm, height of 440mm and thickness of 6.3mm was performed to compare its results with that by assessment according to the A16 guide. The specimen was subjected to creep-fatigue loads with two hours of a dwell time at 600°C and variable primary loads. The creep-fatigue crack behaviours for the two materials were assessed, observed and compared. The results showed that the A16 guide for the austenitic stainless steel was overly conservative for the assessment of creep-fatigue crack initiation while it was reasonably conservative for creep-fatigue crack growth for the present specimen.

The specimen was subjected to creep-fatigue loads with 2 h of dwell time at 600°C and various primary loads. The creep-fatigue crack behaviors for the two materials were assessed, observed, and compared. The results showed that the A16 guide for the austenitic stainless steel was fairly conservative for the assessment of creep-fatigue crack initiation while it was reasonably conservative for creep-fatigue crack growth for the present specimen.
