Best Welding and Manufacturing Practices

Welding Methods: Use TIG or MIG welding for 201 ss coil, with 308L or 309L filler metals for strong, corrosion-resistant joints.
Forming Tips: Highly formable due to its austenitic structure, but avoid excessive cold working to prevent work hardening—annealing may be needed post-forming for 201 ss coil stock.
Processing Tips: Use sharp tools and lubricate during cutting or punching to maintain the surface quality of 201 cold-rolled stainless steel coils or polished finishes.
