What are Stainless Steel 316H Buttweld Fittings?
Stainless Steel 316H Buttweld Fittings are pipe fittings made from grade 316H stainless steel, a high-carbon version of 316 stainless steel. The “H” stands for high carbon content, which enhances strength at elevated temperatures. These fittings are widely used in pressure piping systems and process industries that operate under extreme conditions.
The high carbon content improves creep resistance and mechanical properties, making ASTM A403 WP316H Stainless Steel Buttweld Pipe Fittings ideal for applications involving heat exchangers, boilers, and other high-temperature equipment.
They are available in multiple types such as:
- SS 316H Elbow
- SS 316H Reducer
- SS 316H Tee
- SS 316H Cross
- SS 316H Stub End
- SS 316H End Cap
- SS 316H Pipe Bend
