ASTM A193 B7M Ob chav - xaus Stud + A 194 2HM Heavy Duty Nut

I. ASTM A193 B7M Ob chav-Tau kawg Stud

1. Cov ntaub ntawv yooj yim
Txheem: ASTM A193 / A193M (Alloy Steel Studs rau Kub Kub thiab Siab Siab)
Khoom siv: Chromium{0}}Molybdenum Alloy Steel
Hom: Ob npaug -Ended Stud, Tag Nrho Threaded Stud
Xov: UNC (Unified Coarse Xov), 8UN, Xov Qib 2A
Qhov Loj: Imperial 1/4 "-4", Metric M6-M100

2. Chemical Composition (%)

Table Element C Mn PS Si Cr Mo
Ntau yam 0.38–0.48 0.75–1.00 Tsawg dua lossis sib npaug rau 0.035 Tsawg dua lossis sib npaug rau 0.040 0.15–0.35 0.80–1.15 0.15–0.25

3. Mechanical Properties (Core)
Yam tsawg kawg Tensile Strength: 100 KSI (689 MPa)
Yam tsawg kawg yield zog: 80 KSI (551 MPa)
Elongation: Ntau dua lossis sib npaug li 18%
Hardness: HB 197-235 (HRB 92-99), nrog kev tswj nruj nruj ntawm 235 HB
Kev kho cua sov: quenched thiab tempered

4. Cov yam ntxwv tseem ceeb (Sib txawv ntawm B7)
Sulfide Stress Corrosion Cracking Resistance (SSC): Tsim los rau cov cheeb tsam acidic, nrog rau kev txwv nruj nruj rau cov tawv tawv thiab siab dua
Qhov kub thiab txias: -29 ° -538 ° F (-20 ° F - 1000 ° F)
Kev soj ntsuam yuav tsum tau ua: yuav tsum tau kuaj hardness rau txhua daim, thiab batch cuam tshuam toughness pov thawj yuav tsum tau.

5. Kev kho deg
Feem ntau siv: Blackening, Phosphating, PTFE, Kub-Dip Galvanizing, Cadmium Plating

II. ASTM A194 2HM Heavy Duty Hex Nut

1. Cov ntaub ntawv yooj yim
Cov Qauv: ASTM A194 / A194M (Ntshav rau Kub Kub thiab Siab Siab), ASME B18.2.2 (Heavyweight Hex Txiv Ntoo)
Khoom siv: Medium carbon steel, quenched + tempered
Hom: Heavyweight hex txiv ntseej, wider hla flats tshaj tus qauv hex ceev
Thread: UNC 2B (≤1"), UNC/8UN 2B (>1")
Qhov Loj: Imperial 1/4 "-4", Metric M6-M100

2. Chemical Composition (%)
Table Element C Mn PS Si Range Ntau dua lossis sib npaug rau 0.15 Tsawg dua lossis sib npaug rau 1.00 Tsawg dua lossis sib npaug rau 0.04 Tsawg dua lossis sib npaug rau 0.05 Tsawg dua lossis sib npaug rau 0.40

3. Mechanical Properties
Pov thawj Load: 150 ksi (1034 MPa)
Hardness: HB 159-237
Kev kho cua sov: quenched + tempered, ua kom lub zog sib piv nrog B7M studs

4. Cov yam ntxwv tseem ceeb (Qhov txawv ntawm 2H)
SSC Resistance: Ib yam li B7M Matching specifications, stricter hardness tswj, haum rau acidic ib puag ncig

Matching: Qhov tsuas teev cov txiv ntseej qib rau siv nrog A193 B7M studs

Cov ntsiab lus tseem ceeb ntawm B7M + 2HM Kev sib xyaw

Standard Matching: A193 B7M studs yuav tsum tau ua ke nrog A194 2HM txiv ntseej; 2H txiv ntseej tsis tuaj yeem hloov pauv.

Daim ntaub ntawv: Acidic roj thiab roj teb, refining units, siab hlab ntsha / flange kev twb kev txuas uas muaj H₂S

Strength Matching: Stud tensile zog 100 ksi, txiv ntseej guaranteed load 150 ksi, ua tau raws li ob qhov yuav tsum tau ntawm kub kub, siab siab, thiab corrosion.

Yuav tsum tau txhim kho: Yuav tsum tau ASTM F436 hardened washers; zawm mus rau qhov teev torque kom tsis txhob overtightening thiab kev ntxhov siab concentration.

Common Application Scenarios

Roj thiab Gas Extraction: Cov khoom siv Wellhead, Christmas ntoo, pipeline flanges

Refining thiab Chemical Engineering: Hydrogenation units, acidic dej systems, siab - kub thiab siab - siab reactors

Fais fab: boiler, turbine, tshav kub exchanger kev sib txuas

Lwm tus: Cov hlab ntsha siab, li qub, cov twj tso kua mis uas muaj cov tshuaj sulfur
