GB/T E309-16
AWS A5.4 E309-16
Tlhaloso: A302 ke electrode ea tšepe e sa ruseng ea Cr23Ni13 e nang le sekoahelo sa titanium-calcium. E ka sebelisoa bakeng sa AC le DC ka ts'ebetso e ntle ea ts'ebetso. Tšepe e kentsoeng e na le khanyetso e kholo ea mapetso le khanyetso ea oxidation.
Tšebeliso: E sebelisetsoa ho tjheseletsa mofuta o tšoanang oa tšepe e sa ruseng, lesela la tšepe e sa ruseng, tšepe e bōpehileng joaloka e khethehileng (Cr19Ni9 e tšoana le tšepe e nang le khabone e tlase), tšepe e nang le chromium e ngata, tšepe e nang le manganese e ngata, jj.
