What Is A403 316?
ASTM A403 WP316 Fittings are a grade of pipe fittings that are made up of a high oxidation resistant material. This material is also corrosion resistive, pitting resistive and can withstand strong chemicals and acids. The high temperature and pressure tolerance of this material makes the A403 WP316 Elbow to perform better under the corrosive high pressure curvatures of piping. The corrosion in fluid direction changing joints is high. Due to the impact of the fluid flow, the fitting might break if there was corrosion and or thermal expansion.
Stainless Steel 316 Pipe Fittings Used Austenitic Steel?
The Stainless Steel 316 Pipe Fittings is one of the most used form of the austenitic steel in the piping world. ASTM A403 Wp316 Buttweld Pipe Fittings has slightly less corrosion resistant properties than the A403 WP316 Tee. But both could be used interchangeably in most conditions except where the requirement mandated one over the other. The 316 Pipe Fittings come in different shapes and standards. They could either be seamless or buttwelded. The SS 316 Fittings are much stronger due to the reason that they are heat treated after buttweldiing and can last longer than most other Stainless Steel 316 Tee.
What Is Use Of ASTM A403 WP316 Elbow In Piping?
ASTM A403 WP316 Elbow is used mostly in the domestic applications. The SS 316 Pipe Fittings could be used in commercial and industrial applications. Where the strength is more important than the corrosion resistance, the A403 Grade WP316 Buttweld 45 Deg Elbow could be used. The strength of the Stainless Steel 316 Elbow could be increased through cold working. The SS 316 Fitting can exhibit high strength, durability and weldability. Where, the cost is the major concern, the 316 SS Weld 90 Deg Elbow provide considerable cost cutting over high end alloy materials.

Different Between A403 WP 316 & A403 WP304L
- ASTM A403 WP316 Fittings are a grade of pipe fittings that are made up of a high oxidation resistant material. This material is also corrosion resistive, pitting resistive and can withstand strong chemicals and acids.
- ASTM A403 WP304L Fittings are pipe fittings made for austenitic stainless steel applications with forged material. These are commonly used for pressure piping that could withstand high pressure stress condition.
