ASTM A815 S31803-W Y TEE Butt Welded Fitting B16.9 Oil refining fertilizer Gas
What is ASTM A815 S31803 ?
Duplex stainless steels are extremely corrosion-resistant, work-hardenable alloys. Their microstructure consists of a mixture of austenitic and ferritic phases. As a result, duplex stainless steels display the properties of both austenitic and ferritic stainless steels.
