Grade: SS304L, SS316L, SS321
Standards: ASTM A269
Sizes: 1/4" ~ 2" , 6mm ~ 60mm
Application: Bright annealed tubes have no oxide layer, withstands high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring and flattening without crack, so they're widely used for instrumentation, fluid equipment, automobile locomotives, locomotive brake system, gas equipment manufacturing and laboratory, etc.
