Title:
TWIP, nano Twinning austenitic stainless steel, and its manufacturing method
Document Type and Number:
Japanese Patent JP6047164
Kind Code:
B2
Abstract:
The invention relates to a method of producing a TWIP and nano twinned austenitic stainless steel. The austenitic steel should not contain more than 0.018 wt% C, 0.25-0.75 wt% Si, 1.5-2 wt% Mn, 17.80-19.60 wt% Cr, 24.00-25.25 wt% Ni, 3.75-4.85 wt% Mo, 1.26-2.78 wt% Cu, 0.04-0.15 wt% N, and the balance of Fe. In order to form nano twins in the material the austenitic stainless steel should be brought to a temperature below 0°C, and imparted a plastic deformation to such a degree that the desired nano twins are formed, e.g. to a plastic deformation of around 30%. The invention also relates to the thus produced austenitic stainless steel.
