Ipuleti lensimbi le-ASTM A514 grade A

Ipuleti lensimbi le-ASTM A514 grade A I-ASTM A514 iyinsimbi ecishiwe ephansi futhi ethambile ebiza kancane, into esebenza kahle kakhulu ukuze isetshenziswe ngokwesakhiwo kanye nezicelo zemishini yokugqokwa okuphezulu. Ipuleti lensimbi le-A514 lihlangabezana ne-ASTM International standard A514. Ngokujwayelekile lisetshenziswa njengensimbi yesakhiwo kuma-cranes noma emishinini emikhulu yomthwalo osindayo, i-A514 inikeza amandla aphezulu ngezakhiwo ezishiselayo, ezishintshwayo.

Ulwazi lomkhiqizo

I-ASTM A514 ibanga A wuhlobo lwensimbi ye-ASTM A514. Izakhiwo ezikhonjiwe zifanelekile esimweni esicishiwe nesithambile. Amabha egrafu kumakhadi wezinto ezibonakalayo angezansi aqhathanisa ne-ASTM A514 grade A nalezi: izinsimbi ezihlanganisiwe zensimbi esigabeni esifanayo (phezulu), wonke ama-alloys ensimbi (maphakathi), kanye nesizindalwazi sonke (ngezansi).

Ipuleti lensimbi i-A514 Ibanga A lingaphansi kokucaciswa okujwayelekile kwensimbi kwamandla esivuno esiphezulu i-ASTM A514/A514M.A514GrA ipuleti lensimbi eliyingxubevange elinokushisa okucishayo kanye nokushisa okushisa lapho liginqika. 690Mpa ngokujiya ngezansi kuka-65mm, kanye no-620 Mpa ngogqinsi olungaphezu kuka-65mm, amandla okuqina azoba phakathi kuka-760-895 Mpa. Umkhiqizi angase ashise kabusha amapuleti ahlulekayo ukuhlangabezana nezimfuneko zezakhiwo eziwumshini zalokhu kucaciswa lapho kuginqiswa ipuleti lensimbi elidonsa kanzima elingu-A514GrA.Zonke izivivinyo zezakhiwo eziwumshini zizophindwa lapho okubalulekile kuthunyelwa kabusha ukuze zihlolwe.
