Thaum tsim cov hlab ntsha siab thiab boilers, xaiv ntawmASTM A516 Qib 70thiabASTM A516 Qib 70 (HIC)tuaj yeem ua rau qhov sib txawv ntawm kaum xyoo ntawm kev ua haujlwm nyab xeeb thiab kev puas tsuaj ntawm cov qauv tsis ua haujlwm.
Thaum lawv sib koom tib lub zog txhua yam, lawv cov purity metallurgical thiab kev xeem yuav tsum sib txawv kiag li. Nov yog phau ntawv qhia kev tsim vaj tsev zoo tshaj plaws los pab koj txheeb xyuas cov phaj hlau zoo rau koj qhov project.
A516 Gr 70 vs A516 Gr 70 HIC
| Feature | ASTM A516 Qib 70 (ib txwm) | ASTM A516 Qib 70 (HIC) |
| Phosphorus (P) txwv | Tsawg dua lossis sib npaug li 0.025% | Ultra-Low: Tsawg dua lossis sib npaug rau 0.015% |
| Sulfur (S) txwv | Tsawg dua lossis sib npaug li 0.025% | Ultra-Low: Tsawg dua lossis sib npaug rau 0.003% |
| Kev xeem HIC | Tsis xav tau | Yuav tsum tau (ib NACE TM0284) |
| Sour Service Ua raws cai | Tsis muaj | Yog (rau NACE MR0175) |
| Daim ntawv thov tseem ceeb | Nruab nrab/General Environments | Sour & Wet H₂S Ib puag ncig |

1. Tshuaj muaj pes tsawg leeg & suav nrog kev hloov kho
Thaum cov pa roj carbon monoxide A516 Gr 70 ua raws li cov txheej txheem tshuaj txwv, lubHIC (Hydrogen Induced Cracking)variant undergoes ib tug tshwj xeeb refining txheej txheem. Nws xav tau ultra- qis Sulfur ( Tsawg dua lossis sib npaug li 0.003%) thiab Phosphorus ( Tsawg dua lossis sib npaug li 0.015%). Tsis tas li ntawd, advancedkev kho calcium thiab kev hloov pauv hauv kev suav nrogtau txais kev pom zoo kom ntseeg tau tias cov hlau matrix sab hauv yog cov ntshiab ntshiab, tiv thaiv hydrogen atoms los ntawm kev sib sau thiab ua rau cov hlwv sab hauv.
2. Kev Tshawb Fawb & Kev Xeem (NACE Standard)
A516 Gr . 70:Yuav tsum tau tsuas yog kev ntsuam xyuas niaj hnub zeb: Tensile, Charpy V-Qhov cuam tshuam, UT (Ultrasonic), thiab kev tshuaj xyuas qhov ntev.
A516 Gr. 70 HIC:Yuav tsum xeem dhau nruj tiv thaiv- ntawv pov thawj corrosion. Nws raug kuaj nruj me ntsis raws liTIAB SA TM0284thiab yuav tsum ua raws liNWS MR0175rau kev pabcuam qaub. Cov kab nrib pleb yog tswj nruj me ntsis, kom ntseeg tauCLR, CSR, thiab CTRnyob tsis pub dhau qhov txwv kev nyab xeeb.
3. Daim Ntawv Thov Scope: Thaum twg Koj Xav Tau HIC?
Txheem A516 Gr 70:Zoo meej rau cov kev pabcuam dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau boiler phaj, thiab cov khoom siv hluav taws xob tsim hluav taws xob ua haujlwm hauv kev huv, tsis yog- qhov chaw qaub (tsis ntub H₂S).
A516 Gr 70 HIC:Qhov kev xaiv uas yuav tsum tau ua rau kev lag luam Roj & Gas, petrochemical refineries, desulfurization khoom, thiab cov kua qaub nruab nrab cia tso tsheb hlau luam raug rau tuag.ntub dej H₂S (kev pabcuam qaub)tej yam kev mob.
4. Tus nqi, xa khoom & Tshuag muaj
Lawm, qhov tshwj xeeb refining thiab NACE xeem ua A516 Gr 70 HIC kim dua thiab ib txwm ua qeeb qeeb los tsim dua tus qauv A516 Gr 70.
Txawm li cas los xij, koj tsis tas yuav tos ntev zeb ntau lawm lub sij hawm. NtawmGNEE Steel, peb tuav ib qho kev npaj loj heev - rau- nkoj cov khoom muag ntawm ob tus qauv thiab HIC- kuaj A516 Gr 70 daim hlau, ua tiav nrog tag nrho cov MTCs (Mill Test Certificate).
