STPG410 steel welded yeeb nkab
STPG 410 carbon steel kav muaj cov tshuaj muaj pes tsawg leeg. Lawv feem ntau muaj txog 0.30-0.35% carbon, 0.30-0.90% manganese, 0.040% phosphorus, 0.040% sulfur, thiab me me ntawm silicon. STPG 410 cov kav dej yuav tsum tau ua kom tau raws li cov khoom siv tshwj xeeb, suav nrog lub zog tensile tsawg kawg, lub zog tawm los, thiab elongation. Cov khoom no ua kom cov kav dej muaj peev xwm tiv taus cov kev kub ntxhov.STPG 410 cov kav dej tuaj yeem welded siv cov txheej txheem vuam txheej txheem. Txawm li cas los xij, nws yog ib qho tseem ceeb kom ua raws li cov txheej txheem vuam tsim nyog thiab kev kho cua sov tom qab vuam kom muaj kev ncaj ncees ntawm cov khoom.
