Precision plasma can pierce and cut stainless steel up to around 40mm and high amperage plasma systems can pierce and cut stainless steel up to around 100mm.
Plasma cutting stainless steel sheet.
This is especially true for thicker stainless steel plates where plasma cutting is almost universally considered the best solution.
When a plasma process engineered for cutting 304l is applied to another similar austenitic alloy for example 316l dross and a rough cut edge can result.
With an edge start plasma can cut up to about 160mm.
Precise machine motion controls torch to material distance control and the correct plasma and assist gases all are crucial to producing weld ready plasma cut edges on all stainless steel thicknesses.
304l an austenitic stainless steel is the most commonly used grade worldwide.
