Insimbi ye-ASTM A242

Ukucaciswa kwe-ASTM A242 ukucaciswa okujwayelekile kwensimbi yesakhiwo sokuqina kwe-alloy ephezulu kumalungu esakhiwo lapho ukonga isisindo nokumelana nokugqwala kwe-atmospheric kubalulekile.

Isingeniso somkhiqizo

Ukucaciswa kwe-ASTM A242 ukucaciswa okujwayelekile kwensimbi yesakhiwo sokuqina kwe-alloy ephezulu kumalungu esakhiwo lapho ukonga isisindo nokumelana nokugqwala kwe-atmospheric kubalulekile. Izidingo zezakhiwo zikamshini zicaciswa uhlobo lomkhiqizo (amapuleti namabha, kanye Nokwakheka Kwesakhiwo) nangogqinsi.

Insimbi ye-ASTM A242 inokumelana nokugqwala komkhathi
Ipuleti lensimbi elingaphansi kwezinga le-ASTM A242 liphinde libizwe ngepuleti lensimbi yesimo sezulu, elibhekiselwa ensimbi ebulewe kancane noma ebulawe ngokuphelele. Inokumelana nokugqwala okuhle komkhathi ngakho insimbi ingasetshenziswa ezindaweni eziningi zokusebenza.

Insimbi yesimo sezulu ye-ASTM A242 ingcono kakhulu kunensimbi ye-carbon structural steel enethusi elifakwe noma elingenayo.

Izakhiwo zika-A242:
I-Tensile:
70 ksi min (3/4 nangaphansi), 67 ksi min (3/4-1.5) 63 ksi min (ngaphezu kuka-1.5-4)
Veza:
50 ksi min (3/4 nangaphansi), 46 ksi min (3/4-1.5) 42 ksi min (ngaphezu kuka-1.5-4)
Ubude:
16% iminithi kokungu-8” 19% iminithi koku-2” (kumapuleti abanzi kuno-24”)
