ASTM A449
ASTM A449 inovhara mabhaudhi ane musoro, tsvimbo, uye mabhaudhi eancho mumadhayamita kubva pa1/4 ″ kusvika 3 ″ inosanganisirwa. Iyo isimbi yepakati simba bhaudhi inogadzirwa kubva pakati kabhoni kana alloy simbi inovandudza ma mechanic values kuburikidza nekupisa kurapa maitiro. Yakagadzirirwa general engineering application.
ASTM A449 inenge yakangofanana mumakemikari uye simba kune ASTM A325 uye SAE J429 giredhi 5. Zvisinei, A449 inonyanya kushanduka mupfungwa yokuti inovhara dhayamita yakakura uye haibvumirwi nekugadzirisa kwakasiyana.
