Stainless Steel Square Pipe

ASTM A554 Grade Mt304 Tube, 316 Stainless Steel Square Tube Sizes

Stainless Steel Square Pipe is made up of various stainless steel grades. The square pipes are useful in structural applications as the geometric shape provides extra strength to the pipe. Navstar Steel is a leading manufacturer and supplier of the Stainless Steel Square Pipe products in various scales and dimensions. The dimensions range according to the ASTM, ASME and API standards. The 304 stainless steel is the most used grade. So the ASTM A554 Grade Mt304 Tube is the most used of stainless steel pipes.

The material is strong and corrosion resistant to mild corrosive agents. It has 205MPa minimum yield strength and 515MPa minimum tensile strength and 870 degrees Celsius operating temperature. However, the 316 Stainless Steel Square Tube Sizes are used in aqueous conditions and in chloride ion rich environment because the 304 grade does not have enough corrosion resistance against the chloride ion corrosion. The 316 material has added molybdenum to overcome this obstacle. The 304 Stainless Steel Square Pipe Price is the most cost effective among all other stainless steel pipes. The weight of the pipes per length depends on the wall thickness, outer diameter and the density of the material. Our SS Square Pipe Weight Chart will reveal you the correlation between the grades, diameters, thicknesses and the weights per unit lengths.
