Stainless Steel ERW Pipe SS 304

304 material rust phenomenon, there may be the following reasons:
Chloride ions exist in the environment.
Chloride ions are widely present, such as salt, sweat, sea water, sea breeze, soil and so on. Stainless steel in the presence of chloride ions in the environment, corrosion quickly, even more than ordinary mild steel. Therefore, there are requirements for the use of stainless steel environment, and it is necessary to wipe frequently, remove dust, and keep clean and dry.

Product Introduction

Among the common marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally indicates national standard production, 304 generally indicates ASTM standard production, and SUS304 indicates daily standard production.

product details

Refining furnace raw materials: Using large steel refining furnace steel strip as raw materials, chromium, nickel, carbon content up to national standards.
Strict control error: It has strict standards for the shape, bending, flatness and thickness of the pipe body, and the diameter error is 0.1mm and the wall thickness error is 0.02mm
Fine surface treatment: the brightness of the pipe reaches 6K, the surface is clean and bright, and the drawing surface can be 180# to 320# straight sand and round sand.
Smooth weld: there is no black line on the surface of the pipe body, no strain, smooth and no feel, and nitrogen protection in the inner weld.
