JIS G3441 Alloy Steel Tube
Qhov Japanese Industrial Standard no qhia txog cov yeeb nkab steel hlau, tom qab ntawd hu ua "cov kav dej", siv rau hauv tshuab, tsheb thiab lwm yam tshuab.
JIS G3441 Alloy Steel Tube Supplier-GNEE
Txoj kev tsim cov kav dej yuav tsum yog welded lossis tsis kam vuam. Lub hauv paus ntsiab lus ntawm lub raj yog tsim los yog ua haujlwm txias lossis tsuas yog annealed. Txawm li cas los xij, tus neeg txiav txim tuaj yeem hais qhia txog kev kho cua sov uas tsim nyog uas tsis yog annealing yog tias tsim nyog.
