Q355 A572GR50 C Channel

Q355 yog ib hom hlau. Nws yog ib hom low-alloy high-strength steel structural steel, dav siv nyob rau hauv Choj, tsheb, nkoj, tsev, siab hlab ntsha, khoom siv tshwj xeeb, thiab lwm yam., qhov "Q" txhais tau tias yield zog, 355 txhais tau hais tias lub yield zog ntawm no. steel yog 355MPa, thiab yuav txo nws cov nqi tawm los raws li cov thickness ntawm cov khoom nce.A572Gr50 uas tsis tshua muaj alloy siab zog steel daim hlau yog dav siv nyob rau hauv engineering lug, xws li lub tsev steel lug, siv machinery, mining machinery, hnyav tsheb thauj khoom, choj, siab hlab ntsha, thiab lwm yam., tshwj xeeb tshaj yog rau kev tsim kho thiab engineering machinery qhov chaw yuav tsum tau zoo weldability thiab toughness.

Khoom Description

Kev kho cua sov txheej txheem ntawm Q355 steel
Annealing: Annealing muaj cua sov Q355 steel rau qhov kub siab tshaj nws qhov kub thiab txias thiab tuav nws ntawm qhov kub ntawm lub sijhawm tshwj xeeb, tom qab ntawd maj mam txias nws. Cov txheej txheem pab kho cov microstructure, tshem tawm cov kev ntxhov siab sab hauv, thiab txhim kho machinability thiab ductility.
Normalizing: Normalizing zoo ib yam li annealing, tab sis yuav tsum txias cov hlau nyob rau hauv tseem huab cua es tsis txhob txias nws maj mam. Cov txheej txheem no ua rau lub microstructure zoo dua qub thiab txhim kho cov khoom siv ntawm cov hlau, xws li lub zog thiab toughness.
Quenching thiab tempering: quenching yuav tsum ceev ceev ntawm Q355 steel los ntawm qhov kub thiab txias mus rau chav tsev kub, feem ntau yog siv dej los yog roj. Cov txheej txheem no tsim ib qho nyuaj, nkig hu ua martensite. Cov hlau yog ces tempered los ntawm reheating nws mus rau ib tug tshwj xeeb kub thiab tuav nws rau ib tug tej lub sij hawm kom txo brittleness thiab nce toughness thaum tuav lub siab hardness theem.
Isothermal quenching: Isothermal quenching yog txheej txheem kev kho cua sov uas suav nrog quenching Q355 steel mus rau qhov kub siab tshaj qhov kub ntawm martensitic pib thiab tuav nws ntawm qhov kub ntawm lub sijhawm ntev. Cov txheej txheem no ua rau cov qauv hu ua bainite, uas muaj ob lub zog siab thiab zoo ductility.

ASTM A572 Gr.50 steel yog ib qho American standard High zog Low alloy (HSLA) structural steel. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 345 MPa (50 ksi) thiab feem ntau yog siv rau hauv cov qauv siv xws li kev tsim kho thiab choj. Ntawm qhov tod tes, Q355 steel yog Suav tus qauv qis-alloy high-strength structural steel. Txawm hais tias lawv muaj cov qib zoo sib xws, cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab yuav txawv.

Channel steel yog carbon structural steel siv nyob rau hauv kev tsim kho thiab machinery, yog ib tug complex seem ntawm seem steel, nws seem puab yog zawj-puab. Channel steel yog tsuas yog siv nyob rau hauv lub tsev qauv, ntaub thaiv phab ntsa engineering, mechanical khoom thiab tsheb manufacturing. Hauv kev siv, nws yuav tsum muaj kev sib txuas zoo dua, riveting thiab cov khoom siv kho tshuab dav dav. Cov khoom siv raw khoom siv rau kev tsim cov channel steel yog carbon bonded steel lossis low alloy steel billet nrog cov ntsiab lus tsis tshaj 0.25%. Cov hlau channel tiav yog xa los ntawm kev ua haujlwm kub, normalizing lossis kub dov.
