DIN17175 St 37-2 Ncaj Seam Pipe
Feem ntau, muaj peb hom ST37-2 steel yeeb nkab: thawj ib yog chav kawm A steel (ib lub steel), hom raj no tsuas yog lav cov khoom siv kho tshuab, tsis lav cov tshuaj muaj pes tsawg leeg; Qhov thib ob yog chav kawm B steel (B steel), tsuas yog lav cov tshuaj muaj pes tsawg leeg, tsis lav cov khoom siv kho tshuab; qhov thib peb yog cov hlau tshwj xeeb (C steel), tsis tsuas yog tuaj yeem ua kom cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab kuj tau lees paub.
Cov khoom siv dav dav dav siv los ntawm DIN St37.2 carbon yeeb nkab muaj nyob rau hauv ntau lub xeev xws li kub dov, txias dov, normalized, quenched thiab tempered.
ST37-2 ncaj seam yeeb nkab yog zoo ib yam li peb cov high-zoo carbon structural steel Alloy 20 yeeb nkab, yog li ntawd, nyob rau hauv tej rooj plaub, nws kuj yuav hloov los ntawm Alloy 20 raj.
Tej yam kev mob ntawm ST37-2 steel yeeb nkab: Thaum txiav txim, cov kev xav tau ntxiv xws li kev cuam tshuam, kev kuaj pom qhov tsis zoo, Z-kev taw qhia thiab kev tswj xyuas muaj pes tsawg leeg tuaj yeem ntxiv, thiab GNEE yuav ua tau raws li koj tus kheej xav tau.
