Abstract

PURPOSE: To obtain the titled stainless steel with superior strength and fatigue resistance after aging by adding specified components such as C and N so as to adjust the austenite stability index represented by a specified equation to a specified value.
CONSTITUTION: This spring stainless steel contains, by wt., ≤0.15% C, ≤0.15% N, ≤1.5% Si, 0.5W2% Mn, 5W9% Ni and 13W20% Cr so as to make austenite stability index Md30 represented by the equation -30W80°C and further contains 0.1W1.5% V except the balance Fe and inevitable impurities. This steel is superior to a conventional steel in strength (hardness) and fatigue resistance after aging, manufacturability and workability, has corrosion resistance, and is suitable for use as a material for all kinds of springs.
