Title:

AUSTENITIC STAINLESS STEEL

Document Type and Number:

WIPO Patent Application WO/2024/043080

Kind Code:

A1

Abstract:

This austenitic stainless steel is configured such that, when the amount of hydrogen released at a temperature ranging from 25°C to 800°C at a temperature elevation rate of 100°C/h is determined by thermal desorption analysis of hydrogen, the amount of released hydrogen [H] is less than 10.0 ppm, the hydrogen release peak temperature [Tp] is 350°C or higher, the hydrogen release peak rate [Rmax] is 0.050 ppm/min or less, and the number density of a compound having a diameter of 0.1 μm to 2 μm is 1.0 to 10.0 pcs./mm2.
