ASTM A815 S31803-W Steel Y Shape Tees Pipe Fittings
ASTM A815 S31803-W Steel Y Shape Tees Pipe Fittings
YUHONG supplies ASTM A815 S31803 duplex steel Y shape Tees. This duplex stainless steels are extremely corrosion resistant, work hardenable alloys.
Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels.
The steel ASTM A815 S31803 has many features: Corrosion resistant, Accurate dimensions, Can sustain high pressure & temperature load, Rust proof finish, Smooth transition from flange thickness to pipe, Ensure excellent stress distribution,etc.
