seamless alloy steel tubing
A333 seamless steel yeeb nkabyog cov khoom siv hlau dav siv hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob fais fab thiab lwm yam kev lag luam.
A333 seamless alloy steel yeeb nkab muaj siab zog thiab hardness, thiab muaj zoo plasticity thiab toughness. Ntawm chav tsev kub, nws lub zog tensile tuaj yeem ncav cuag 500 ~ 700MPa, yield zog yog 270 ~ 410MPa, thiab elongation yog 18% ~ 22%. Ntawm qhov kub thiab txias, nws lub zog thiab hardness yuav tsis txo qis, thaum muaj kev cuam tshuam zoo thiab qaug zog.
Cov khoom tseem ceeb ntawm A333 tsis tshua muaj kub steel yeeb nkab muaj xws li hlau, carbon, chromium, npib tsib xee, manganese thiab lwm yam khoom. Ntawm lawv, chromium muaj kev tiv thaiv corrosion zoo heev, thaum ntxiv cov npib tsib xee ntxiv txhim kho corrosion kuj thiab toughness ntawm cov khoom. Tsis tas li ntawd, A333GR.6 seamless steel yeeb nkab kuj muaj qee qhov nyiaj ntawm silicon, phosphorus, sulfur thiab lwm yam, uas muaj qee yam cuam tshuam rau cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov khoom.
