What is 304L Precision Stainless Steel Sheet?
304L precision stainless steel plate is a high-precision stainless steel plate made through precision processing (such as cold rolling, heat treatment, surface treatment, etc.). Its core features are low carbon content, excellent corrosion resistance, high-precision dimensional tolerance and surface quality, and it is suitable for industrial fields with extremely high requirements on material performance and precision.

304L stainless steel precision plate Advantages
304L stainless steel precision plate has stricter tolerance control (such as 0.5mm plate thickness tolerance ±0.01mm, ordinary plate ±0.05mm), suitable for precision assembly, through bright annealing or mirror polishing, roughness Ra≤0.2μm (ordinary plate Ra≤0.8μm), no oxide scale, pitting; after grain refinement treatment, ductility is increased by 20%, making it easier to realize complex forming processes such as deep drawing and precision bending.
