5140 Hlau Phaj 1.7035 41Cr4 SCr440 Alloy Steel

AISI 5140 steel yog dab tsi?

ASTM qib 5140 yog ib qho qauv hlau alloy steel qib hauv ASTM A29 tus qauv rau kev siv dav dav. 5140 steel phaj yog dav siv nyob rau hauv qis thiab nruab nrab qhov kev nyuab siab qhov chaw rau tsheb, cav thiab tshuab qhov twg nyuaj, hnav resisting nto yog xav tau. Gnee yog tus kws tshaj lij 5140 phaj & round bar tus neeg muag khoom thiab peb khaws ntau qhov loj me rau 5140 phaj hauv Tshuag rau kev xa khoom sai. Tiv tauj peb rau ib qho AISI 5140 phaj cov ntaub ntawv thov thiab zoo tshaj 5140 qib steel nqi.

Competitive Advantage rau AISI 5140 khoom steel phaj hauv Gnee:

• Muaj nyob rau hauv Tshuag rau kev xa khoom sai
• Siab zog,
• Siab tenacity
• Zoo hardenability
• High tsis kam rau thermal zog.
• Tus nqi sib tw

1. Kev xa khoom ntau ntawm AISI / ASTM 5140

Round Bar: txoj kab uas hla 20mm - 300mm

Hlau Phaj thiab Steel Block: thickness 10-200mm x dav 300-2000mm

• 10-80mm thickness 5140 phaj muaj txhua lub sijhawm hauv Tshuag,
• 90-200mm thickness phaj yuav tsim tshiab nyob rau hauv 15-30 hnub ua lub sij hawm.

Nto Finish: Dub Nto, Milled Nto lossis Polished Deg raws li qhov xav tau.

5. Forging ntawm 5140 Alloy Steel

Kub txheej txheem kub: 1050-850 ℃.

6. ASTM 5140 Steel Thaum tshav kub kub kho

• Mos Annealing

Kub rau 680-720 ℃, txias maj mam. Qhov no yuav tsim qhov siab tshaj plaws 5140 hardness ntawm 241HB (Brinell hardness).

• Noramlizing ntawm steel qib 5140

Kub: 840-880 ℃.

• Hardening ntawm 5140 forged steel

Harden los ntawm qhov kub ntawm 820-850, 830-860 ℃ tom qab dej los yog roj quenching.

• Tempering ntawm SAE 5140 khoom

Tempering kub: 540-680 ℃.

7. Daim ntawv thov ntawm AISI Qib 5140

AISI 5140 steel tuaj yeem siv rau qhov qis thiab qis qis rau cov tsheb, cav thiab tshuab qhov twg nyuaj, hnav tiv thaiv qhov chaw xav tau. Hardness li nto hardened txog 54 HRC. SAE 5140 steels kuj tseem tuaj yeem ua rau kev lag luam marine engineering, tshuaj ua cov nroj tsuag, boiler & siab hlab ntsha, nuclear fais fab nroj tsuag thiab lwm yam.
