A method for sinking a cylindrical workpiece made of stainless austenite steel

摘要

A method for sinking of a cylindrical part of a cylindrical workpiece made of stainless austenite steel in an axial direction of this cylindrical part, characterized in that a art of stretching of the cylindrical part of this work piece is designed in such a way that a wall thickness - reduction proportion of [(1 – t₁/T₀) × 100] of the cylindrical part than in a range of from 35 – 45% is selected in a lying position, where t₀ a wall thickness value of the cylindrical part in front of the art of stretching, while t₁ a wall thickness value of the cylindrical part of this art represents stretching process.
