When comparing stainless steel wires of the same diameter and in the same processing condition, a clear pattern emerges in tensile strength: 304 > 304L > 316L This difference is not accidental — it’s closely tied to the material’s chemical composition and processing history: • Carbon (C) content: Higher carbon levels increase tensile strength by solid-solution strengthening, but may affect corrosion resistance. • Manganese (Mn) content: Boosts strength and hardenability. • Silicon (Si) content: Improves strength and oxidation resistance. • Drawing & annealing processes: The degree of cold work and annealing temperature/time directly impact both strength and ductility. In the cut-resistant yarn industry, tensile strength is a key performance indicator because it relates to the glove’s resistance to blade penetration.
However, strength alone is not enough. We must also ensure the flexibility and linearity of the wire after blending into yarns. A wire that is too stiff or prone to “spring-back” (forming spiral curls) can cause processing issues and reduce wearer comfort. The balance: • High tensile strength for cut protection • Good flexibility & straightness for smooth yarn blending and comfortable end-use At Bashan, we optimize both material selection and cold-drawing/annealing parameters to deliver stainless steel wires that meet these dual requirements — ensuring our yarn partners don’t have to choose between protection and comfort.
