ASTM A299 Qib A Boiler Steel Phaj
A299 GrA hlab ntsha steel phaj yog lub siab hlab ntsha hlau tsim rau kev siv cryogenic, qhov no ua tiav los ntawm kev txo cov phosphorus thiab sulfur hauv cov hlau. A299 GrA boiler steel phaj yog cov tsis yog- alloyed zoo steel uas ua tau raws li cov kev cai tshwj xeeb rau cov khoom tiaj tus rau cov khoom siv siab.
Raws li ASTM A299 / A299M tus qauv, cov txheej txheem hauv qab no yuav tsum raug xaiv rau lub nkoj siab steel phaj A299 Qib A thiab A299 Qib B: S1. Kev kho lub tshuab nqus tsev, S2. Kev txheeb xyuas cov khoom, S3. Mechanical test specimens simulated for post-weld heat treatment, S4. Ntxiv tensile xeem, S5. Charpy V-notch impact test, S6. Poob qhov hnyav, S7. Kub tensile xeem.
