309S Cold Drawn Stainless Steel Pipe

309S Cold Drawn Stainless Steel Pipe

Characteristics With the low content of carbon(Max 0.020%) in 904L, there will be no precipitation in common heat treatment and welding. This eliminates the risk of inter-granular corrosion that occurs after general heat treatment and welding. Because the carbon content of 904L is very low (Max...


The 309S is a low carbon stainless steel derived from 309 stainless steel for use in welding applications. The low carbon content minimizes carbide precipitation near the weld zone. Carbide precipitation can cause intergranular corrosion (welding corrosion) in stainless steel in certain environments. Due to the low carbon content of this stainless steel, no chemical precipitation occurs during normal heat treatment and welding. This eliminates the risk of corrosion occurring after general heat treatment and welding. Due to the high content of chromium, nickel and molybdenum, the element Cu is added, so that the stainless steel tube can be passivated even in a reducing environment, for example it can be passivated in sulfuric acid and formic acid.

Weight Calculation 

Weight(kg)=Length(m)*Width(m)*Thickness(mm)*Density Value 

Specific Gravity of Stainless Steel: 

Chromium Stainless Steel 7.75 tons/M3 

Chromium Nickel Stainless Steel 7.93 tons / M3 

Iron 7.87 tons/M3

Theoretical Weight Calculation Formula for Stainless Steel Plate

Theoretical Weight: length(mm) * width (mm)* thickness (mm) * density = weight(kg)
