1045 STEEL FORGING
Thaum tshav kub kub AISI 1045 nrog ob kauj ruam, thawj qhov kub thiab txias rau 750oC – 800 oC, tuav lub sijhawm tsim nyog, tom qab ntawd ua kom sov qhov kub txog li 1100oC – 1200 oC, tuav lub sij hawm txaus rau cov hlau kom huv si. Yam tsawg kawg nkaus forging kub 850 degree, yog li tsis txhob forge hauv qab nws.AISI 1045 steel yuav tsum tau txias kom qeeb li sai tau nyob rau hauv tseem huab cua los yog nyob rau hauv xuab zeb tom qab forged.
1045 STEEL NORMALIZING
Normalizing yog siv los ua kom zoo dua cov qauv ntawm forgings uas yuav tau txias tsis sib xws tom qab forged, thiab suav tias yog kev kho mob ua ntej kev kho cua sov kawg.Normalizing kub rau AISI 1045 steel yuav tsum tau nqa tawm ntawm 870 degree -920 degree . tuav lub sij hawm tsim nyog rau cov hlau kom huv si kom tiav cov ferrite rau austenite transformation.Soak rau 10 - 15 feeb, ces txias hauv huab cua.
1045 STEEL ANNEALING
Annealing yog suav tias yog kev kho mob tsim nyog rau machining.AISI 1045 yuav tsum tau nqa peb ntawm qhov kub ntawm nominal ntawm 800 degree -850 degree, tuav lub sij hawm tsim nyog rau cov hlau kom sov kom huv si, tom qab ntawd rauv cua txias.
1045 STEEL HARDENING
AISI 1045 tuaj yeem ua kom tawv tawv kom tawv tawv thiab lub zog.oC – 860oC, tuav lub sij hawm tsim nyog rau cov hlau kom sov tsis tu ncua, tsau rau 10 -15 feeb ib 25 hli ntawm seem, thiab quench hauv dej los yog roj.Tempering yuav tsum tau ua raws li tam sim ntawd tom qab quenched.
1045 STEEL TEMPERING
Tempering yuav raug coj los ua kom zoo dua cov cuab yeej tom qab quench.AISI 1045 steel feem ntau rhuab mus rau 400oC – 650oC raws li qhov xav tau, tuav kom txog thaum ntsuas kub tsis sib xws thoob plaws hauv ntu, tsau rau 1 teev ib 25 hli ntawm ntu, thiab txias hauv huab cua.
1045 STEEL APPLICATION
Piv nrog rau AISI 1020, AISI 1045 muaj cov hlau tsis tshua muaj hlau, tab sis tuaj yeem ua nplaim taws lossis induction hardening kom tau txais lub zog siab, thiab tau siv dav hauv ntau lub lag luam uas xav tau ntau lub zog, hnav tsis kam,
Cov ntawv thov xws li Axles, Bolts, Txuas Qws, Hydraulic Clamps, Rams, Pins, Rolls, Studs, Shafts, Spindles, Sockets, Lub teeb iav thiab lwm yam.
