Kana zvasvika pakushandiswa kwekuvaka nekuvaka, kusarudza zvinhu kwakakosha kuti ive nechokwadi chekuti zvinhu zvakachengeteka, zvinogara kwenguva refu, uye zvinoshanda. Chimwe chezvinhu zvinoremekedzwa zvikuru muindasitiri iyi ndeche Simbi yeASTM A252 Grade 3. Iyi tsananguro yakakosha zvikuru pakugadzira mapaipi epombi anoshandiswa munheyo dzakadzika, zvichiita kuti ave chinhu chakakosha mumapurojekiti akasiyana-siyana ekuvaka.
ASTM A252 imhando yakajairwa yakagadzirwa neAmerican Society for Testing and Materials (ASTM) iyo inotsanangura zvinodiwa zve welded uye musonopombi yesimbimapombi. Giredhi rechitatu ndiro giredhi repamusoro-soro mune izvi, rine simba rekukura risingasviki 50,000 psi (345 MPa). Izvi zvinoita kuti ive yakakodzera kune mashandisirwo anoda simba rakawanda rekutakura mutoro uye kuramba kuchinjika.
Chimwe chezvakanakira zvikuru zveASTM A252 Giredhi 3 ndechekuti inogona kuchinjika zvakanaka, izvo zvinoita kuti ikwanise kugadzirwa nekuiswa zvakanaka. Makemikoro esimbi iyi anosanganisira zvinhu zvakaita sekabhoni, manganese, uye silicon, izvo zvinoita kuti irambe yakasimba uye yakasimba. Pamusoro pezvo, chinhu ichi chinogona kutsungirira mamiriro ekunze akaoma, zvichiita kuti chikwanise kushandiswa munzvimbo dzemugungwa nedzimwe nzvimbo dzakaoma.
Kutaura zvazviri, ASTM A252 Giredhi 3 inowanzo shandiswa mukuvaka mabhiriji, zvivakwa, uye mamwe mapurojekiti ezvivakwa anoda nheyo dzakadzika. Kugona kwayo kutsigira mitoro inorema uku ichichengetedza hunhu hwayo kwakakosha pakugara kwenguva refu uye kuchengetedzeka kwezvivakwa izvi.
Muchidimbu,ASTM A252 Giredhi 3Simbi chinhu chakakosha muindasitiri yekuvaka, ichipa simba uye kugara kwenguva refu zvinodiwa pakushandisa nheyo dzakadzika. Kunzwisisa hunhu hwayo uye mabhenefiti ayo kunogona kubatsira mainjiniya nevanoita mabasa ekuvaka kuti vasarudze zvinhu zvemapurojekiti avo, zvichizoguma nezvivakwa zvakachengeteka uye zvakavimbika.
