SUS301-CSP Yongjin Stainless Steel-HARD (Cold-Worked/High-Tensile)

Typical Tempers: 1/4H‑hard, 1/2H‑hard, 3/4H‑hard, H‑Full hard ,EH-Extra Hard ,achieved by cold rolling post-annealing

Advantages:

• Exceptional strength and springback — up to +250% strength compared to annealed state.
• Suitable for springs, clamps, reinforcement ribs, and structural components requiring high yield and endurance.

Ductility: As hardness increases, elongation decreases (e.g., full-hard ~9% elongation), but still usable for forming in cold-work mode
