ASTM A335 Umuyoboro wibyuma 42CRMO

Umuyoboro wa Alloy Steel ukoreshwa mubisabwa bisaba imiterere irwanya ruswa iringaniye kandi iramba kandi ku giciro cyubukungu. Kubivuga mu buryo bworoshye, imiyoboro ivanze ikundwa muri utwo turere aho imiyoboro ya karubone ishobora kunanirwa. Hano hari ibyiciro bibiri byibyuma - ibinini binini hamwe nicyuma gito. Imiyoboro igizwe nicyuma giciriritse gifite ibintu bivangavanze biri munsi ya 5%. Mugihe ibivangavanze byibyuma binini cyane bishobora kuba hagati ya 5% kugeza kuri 50%. Bisa na byinshi bivangwa nubushobozi bwumuvuduko wakazi wa Alloy Steel Seamless Umuyoboro uri hejuru ya 20% kuruta umuyoboro usudutse. Mubisabwa rero bifite umuvuduko mwinshi wakazi nkibisabwa, gukoresha umuyoboro udafite ishingiro bifite ishingiro. Nubwo ikomeye kuruta umuyoboro usudira, igiciro kiri hejuru cyane. Byongeye kandi, ibyago byo kwangirika hagati yimiterere yubushyuhe bwibasiwe na weld ni byinshi mubicuruzwa byasuditswe. Itandukaniro rigaragara hagati ya Alloy Steel Welded Pipe nigicuruzwa kitagira ikidodo ni latitudinal seam yuburebure bwumuyoboro. Nyamara, uyumunsi, hamwe niterambere ryikoranabuhanga, ikidodo kiri kumuyoboro wa Alloy Steel ERW gishobora kugabanuka cyane hakoreshejwe uburyo bwo kuvura hejuru, kuburyo bikomeza kutagaragara mumaso yabantu.
