Alloy 20 Tiwbiau

Gydag amrywiaeth eang o diwbiau ar gael ar y farchnad, mae categoreiddio yn dod yn anodd. Mae tiwb aloi 20 yn un o lawer o diwbiau aloi. Mae'n cynnwys nicel, cromiwm a haearn. I ddechrau, datblygwyd tiwbiau aloi 20 ERW i'w defnyddio mewn amgylchedd ag amlygiad asid sylffwrig yn bennaf mewn melinau mwydion a phapur. Yn ddiweddarach, oherwydd priodweddau ymwrthedd cyrydiad tiwbiau Alloy 20, ehangwyd ei lled band i weddu i ddiwydiannau petrocemegol, cynhyrchu pŵer a chemegol.
