Cold Drawn Seamless Steel Tube thiab Yeeb Nkab
Txheej txheem cej luam
Cold drawn seamless steel tubes thiab cov kav dej yog tsim los ntawm cov txheej txheem uas lub raj lossis cov yeeb nkab tau kos los ntawm kev tuag thiab dhau ntawm lub mandrel, tsis tas yuav tsum muaj kev sib txuas lossis kev koom ua ke. Qhov no ua rau cov khoom lag luam nrog qhov ntev, du nto tiav, thiab cov khoom siv kho kom zoo dua qub piv rau cov khoom kub dov los yog welded. Cov yam ntxwv tseem ceeb ntawm txias kos seamless steel raj thiab kav dej muaj xws li:
Yam tsawg kawg nkaus: Cov txheej txheem kos duab txias tso cai rau kev ua siab ntev thiab qhov tseeb qhov ntev.
Smooth nto tiav: Qhov tsis muaj vuam seams ua kom lub ntsej muag sab hauv thiab sab nrauv tiav, uas yog qhov zoo rau ntau yam kev siv.
Txhim kho cov khoom siv kho tshuab: Kev kos duab txias ua kom zoo dua cov qauv ntawm cov hlau, uas ua rau muaj zog ntxiv, hardness, thiab toughness.
Ntau qhov ntau thiab tsawg thiab cov duab: Cold drawn seamless steel tubes thiab kav dej muaj nyob rau hauv ntau qhov ntau thiab tsawg, duab, thiab ntev kom haum rau ntau hom kev lag luam.

Qib Steel
Cov qib steel feem ntau rau cov khaub thuas kos seamless steel raj thiab cov kav dej yog ASTM A519 Qib 1020. Cov qib no muaj qhov sib npaug zoo ntawm cov khoom siv kho tshuab, kev ua haujlwm, thiab kev sib txuas, ua rau nws tsim nyog rau ntau yam kev siv.
Daim ntawv thov
Cold drawn seamless steel raj thiab kav dej pom daim ntawv thov hauv ntau qhov kev lag luam, suav nrog:
Automotive: rau kev tsim cov khoom xws li hydraulic thooj voos kheej kheej, poob siab absorbers, thiab tsav ncej.
Machinery: rau zus tau tej cov precision mechanical Cheebtsam thiab qhov chaw.
Roj thiab Roj: hauv kev ua haujlwm drilling thiab tshawb nrhiav, nrog rau kev tsim cov kav dej thiab khoom siv.
Aerospace: rau fabrication ntawm structural Cheebtsam thiab hydraulic systems.
Cov qhab nia xaiv tau
Thaum ASTM A519 Qib 1020 tau siv dav, muaj ob peb lwm qib muaj nyob ntawm cov kev cai tshwj xeeb:
ASTM A519 Qib 1010: Muab cov khoom zoo sib xws nrog cov ntsiab lus qis dua.
ASTM A519 Qib 1045: Muab ntau zog thiab hardness piv rau Qib 1020, haum rau cov ntawv thov kom muaj zog thiab hnav tsis kam.
ASTM A519 Qib 4130: Muaj chromium thiab molybdenum rau kev txhim kho corrosion thiab siab - kub lub zog, feem ntau siv hauv aerospace thiab roj thiab roj kev lag luam.
