I-ASTM A449
I-ASTM A449 igquma iibholithi ezinentloko, iirodi, kunye neebholiti zeankile kwiidayamitha ukusuka kwi-1/4″ ukuya kwi-3″ equkiweyo. Yibholiti yamandla ephakathi eyenziwe kwikhabhoni ephakathi okanye intsimbi yealloy ephuhlisa amaxabiso ayo omatshini ngenkqubo yokuphatha ubushushu. Yenzelwe izicelo zobunjineli ngokubanzi.
I-ASTM A449 iphantse ifane kwikhemistri kunye namandla kwi-ASTM A325 kunye ne-SAE J429 ibakala lesi-5. Nangona kunjalo, i-A449 ibhetyebhetye ngakumbi ngengqiqo yokuba igubungela uluhlu olukhulu lwedayamitha kwaye ayithintelwa lubumbeko oluthile.
