Cov Tub Ntxhais Nickel Alloy 20 • UNS N08020 • 2.4660 Duab Tshwj Xeeb

Cov Hlab Hlau Nickel Alloy 20 • UNS N08020 • 2.4660

Kev Piav Qhia Luv:

Cov Hlab Hlau Nickel Alloy 20. Alloy 20 yog ib qho hlau nickel-hlau-chromium alloy nrog ntxiv tooj liab thiab Molybdenum. Ruaj khov nrog niobium tiv thaiv kev rhiab heev thiab ua rau muaj kev xeb intergranular. Alloy 20 muaj kev tiv thaiv zoo heev rau kev xeb dav dav, kev xeb pitting thiab kev xeb crevice hauv cov tshuaj uas muaj chlorides thiab sulfuric, phosphoric thiab nitric acids.
