04Cr11Nb Mechanical Properties

diameter d mm	Tensile Strength σ_b Mpa	Elongation or Extension Rate δ %
d=1.00~3.00	Soft Steel Wire 480~700	Soft State Wire (Elongation after Break) ≥20
d>3.00~16.0	460~680	≥20

①soft - Wire is subjected to bright heat treatment, or after heat treatment, it undergoes pickling or similar processes to remove surface scale.
②Lightly drawn- Wire is drawn to finished dimensions with a small reduction in cross-section after heat treatment.
③Cold drawn - Wire undergoes conventional drawing after heat treatment, which is the process of forming at room temperature through methods such as die drawing or roll drawing.
