GNEE yog ib qho ntawm cov pioneers hauv kev muabDIN2391 ST45 carbon steel seamless kav, yog li koj tuaj yeem xaiv cov kav dej zoo thiab tau txais qhov kev ntsuam xyuas koj xav tau ntawm tus nqi zoo tshaj.
DIN 2391 ST45 cov kav dej txhua yam muaj lub zog tensile zoo thiab cov txiaj ntsig zoo thiab pom muaj zog toughness, ua rau lawv zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj zog. Tsis tas li ntawd, DIN 2391 ST45 precision kav yog tsim los ntawm cov tshuaj muaj pes tsawg leeg ntawm cov pa roj carbon, phosphorus, silicon, manganese, nitrogen, thiab sulfur, uas ua rau lawv zoo qhov tseeb.
DIN 2391 St45.4 seamless pressure pipes yog siv nyob rau hauv high-temperature daim ntaub ntawv. Piv nrog rau cov kav dej welded, cov kav dej seamless tuaj yeem tiv taus li 20% siab dua yam tsis muaj kev tawg. Kev kub siab hauv cov kav dej tuaj yeem tso siab rau cov kav dej welded, ua rau lawv tawg ze ntawm cov seams.
