SA633 Qib A yog dab tsi?
SA633 Qib A yog asiab -lub zog, quenched thiab tempered alloy steel phajteev nyob rau hauvASTM A633 Cov Khoom Siv Hluav Taws Xob. Nws yog tsim raucov hlab ntsha siab, boilers, hnyav machinery, thiab kev siv cov qauvxav tau zoo heevtoughness, weldability, thiab cuam tshuam tsis kam. Tsis zoo li corrosion-cov hlau tsis muaj zog, nws qhov txiaj ntsig tseem ceeb yogsiab zog ua ke nrog superior toughness, ua rau nws zoo tagnrho rau cov khoom uas raug kev ntxhov siab lossis cuam tshuam.

Qhov txawv ntawm lawv yog dab tsi?
Qhov txawv ntawm SA633 Qib A thiab SA588 Qib K
| Khoom | SA633 Qib A | SA588 Qib K |
|---|---|---|
| Hom hlau | Quenched thiab tempered alloy steel | Siab-lub zog, qis- alloy (HSLA) corrosion-resistant steel |
| Yield zog (min) | 345 MPa rau | 450 MPa |
| Tensile zog | 485-620 MPa | 510-655 MPa |
| Elongation | 18–20% | 16–18% |
| Toughness | Siab, tsim los rau kev cuam tshuam | Zoo, tsim rau cov qauv loads thiab corrosion kuj |
| Corrosion Resistance | Txuj | Txhim kho atmospheric corrosion kuj |
| Tej kev siv | Cov hlab ntsha siab, boilers, hnyav machinery | Cov choj, cranes, cov qauv kev lag luam, cov qauv sab nraum zoov |
| Qhov tseem ceeb Advantage | Superior toughness nyob rau hauv kev ntxhov siab | Lub zog siab zog thiab corrosion kuj rau sab nraum zoov siv |
Kev tsom xam
SA633 Qib A yogquenched thiab tempered, prioritizing toughness thiab cuam tshuam tsis kam, ua rau nws zoo tagnrho raucov hlab ntsha siab, boilers, thiab siab - cov tshuab muaj zog.
SA588 Qib K yog acorrosion-resistant HSLA steelnrog ntau dua yield zog, haum rauhnyav-cov dej num sab nraum zoovzoo li cov choj, cranes, thiab cov txheej txheem kev lag luam.
Kev xaiv nyob ntawm sebcuam tshuam / toughness nyob rau hauv kev ntxhov siab(SA633) orlub zog ntxiv rau corrosion kuj rau kev siv sab nraum zoov(SA588) yog qhov tseem ceeb.
GNEE Steel kuj muab ntau yam siab - lub zog steel phaj, xws li A514 Qib F, A572 Qib 50, A588 Qib A, S355JR, S690Q, SS400, S690QL, Q345B, Q345E, thiab lwm yam.
