ASTM A516 GR 70 yog cov pa roj carbon steel phaj tsim los rau kev weldability zoo thiab tawv, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej zoo. Cov tshuaj muaj pes tsawg leeg, raws li tau teev tseg los ntawm ASTM cov qauv, yog nruj tswj hwm kom ntseeg tau tias kev ua haujlwm ntawm cov hlab ntsha siab.

Cov Lus Cim Tseem Ceeb:
Cov pa roj carbon: Capped ntawm 0.27% kom tswj tau qhov weldability thiab tiv thaiv kev nyuaj siab dhau.
Manganese: Txhim kho lub zog thiab tawv, tseem ceeb rau siab - ib puag ncig siab.
Phosphorus thiab Sulfur: Cov qib qis txo qis brittleness thiab txhim kho qhov tawv tawv.
Silicon thiab Aluminium: Xyuas kom cov hlau raug tua tag nrho, txo cov pa roj thiab txhim kho cov khoom siv kho tshuab.
Gangsteel's ASTM A516 GR 70 daim hlau ua raws ob qho tib si ASTM thiab ASME SA516 GR 70 cov qauv, nrog rau kev sim ntxiv kom paub tseeb cov tshuaj sib xws.
