Cov Nta Tseem Ceeb
High tensile lub zog: Cov phiaj no muaj tsawg kawg yog lub zog ntawm 345 MPA thiab tensile lub zog xws li 48-655 MPa, ua rau lawv muaj peev xwm txhawb cov txheej txheem hnyav.
Tshaj teb cov tawv: nrog cov kev cuam tshuam zoo tseem ceeb heev txawm tias kub hnyiab, lawv xyuas kom haum kev nyab xeeb hauv qab kev ua kom zoo lossis huab.
Zoo tshaj Weldability: Cov phiaj hlau tuaj yeem yooj yim rau kev ua si nyuaj rau kev ua haujlwm nyuaj, txo cov kev ua haujlwm thiab cov nqi.
Qhov xwm txheej ntev: Tsim rau ntev -}}}} Cov chaw ua haujlwm tsis zoo rau cov neeg qaug zog thiab xeb, haum rau ob tus pej xeem thiab cov qauv txheej txheem.
Cov Khoom Siv
Cov phiaj no muaj tsawg kawg yog lub zog muaj zog ntawm 345 MPa thiab lub zog tensile xws li 485 txog 655 MPa, nrog elongation ntawm ntau dua lossis sib npaug rau 20%. Lawv kuj tswj hwm kev ncaj ncees ntau dua los yog sib luag rau 27 degree, kom muaj kev nyab xeeb lossis muaj kev kub ntxhov hauv qis.
Choj tsim kev tsim kho: Girders, lawj daim hlau, thiab trusses, muaj peev xwm nrog kev thauj khoom hnyav.
Kev lag luam Machinery: thav duab thiab cov txheej txheem sib xyaw rau cranes, siv machinery, thiab cov cuab yeej hnyav.
Tsev qauv qauv: kab, kab teeb, thiab kev txhawb nqa moj khaum qhov twg muaj zog thiab weldability yog qhov tseem ceeb.
Tubrog nkoj thiab ntug dej hiav txwv: chaw nres nkoj vaj tse, cov nkoj nres nkoj, thiab cov khoom siv hluav taws kub tau txais txiaj ntsig los ntawm cov steel lub durability thiab tawv.
