Understanding 201 Stainless Steel J Series (J1, J2, J3, J4, J5) | WinscoMetal

2025-04-18

201 stainless steel J series has distinct differences in chemical composition, processing performance, and applications. Here’s a breakdown to help you choose the right material:

✅ Copper content (affects flexibility & workability): J4 > J1 > J3 > J2 > J5
✅ Carbon content (affects hardness & corrosion resistance): J5 > J2 > J3 > J1 > J4
✅ Hardness: J5, J2 > J3 > J1 > J4 (Higher hardness is good for surface treatment but may crack when bent).
