ASTM A106 Qib B yeeb nkabyog suav tias yog sib npaug rau ASTM A53 Qib B thiab API 5L Qib B raws li cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab. Nws yog ib hom carbon steel uas muaj qhov tsawg kawg nkaus tawm lub zog ntawm 240 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa.
A106GRB, tseem hu ua ASTM A106Gr B, yog cov khoom siv carbon steel yeeb nkab qauv tsim nyog rau qhov kub thiab txias ua haujlwm ib puag ncig. Nws cov khoom tseem ceeb yog hlau, carbon, manganese, silicon thiab lwm yam khoom. Cov khoom siv no muaj zog heev thiab corrosion kuj thiab tuaj yeem siv rau hauv cov kav dej thiab cov hlab ntsha hauv cov roj av, cov roj av, tshuaj lom neeg kev lag luam, nkoj tsim, hluav taws xob thiab lwm yam haujlwm.
Raws li cov khoom tseem ceeb ntawm cov yeeb nkab steel, A106GRB kuj muaj qhov kub thiab txias tsis kam. Nws qhov kev ua haujlwm siab tshaj plaws tuaj yeem ncav cuag 425 degree, yog li nws tau siv dav hauv ntau lub sijhawm uas yuav tsum tau tiv taus qhov kub thiab txias, xws li thermal zog tsim, roj refining, tshuaj lom neeg kev lag luam thiab lwm yam lag luam. Tib lub sijhawm, A106GRB kuj muaj lub zog txhua yam thiab hnav tsis kam, thiab tuaj yeem tiv taus cov khoom siv loj.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias A106GRB muaj kev tiv thaiv corrosion tsis zoo thiab yooj yim cuam tshuam los ntawm corrosion. Yog li ntawd, thaum siv cov khoom siv no, kev saib xyuas yuav tsum tau them nyiaj rau kev tiv thaiv corrosion ntawm sab hauv thiab sab nraud ntawm cov kav dej kom ntseeg tau tias kev ua haujlwm nyab xeeb thiab siv tau ntev ntawm cov kav dej.
