不锈钢折弯回弹：V 槽、R/t 与轧制方向怎么定

Springback in austenitic stainless steel is significantly larger than in carbon steel. Control it by: selecting V-die width ≈ 8–10×t, controlling R/t ratio, orienting the bend line relative to rolling direction, and compensating angle in tooling. For 304/316L with t≤3mm, typical overbend is 1–3°.
