Khoom nta

Tsawg -} alhoy alleoy qauv hlau kuj tseem hu ua cov qes qis- alloy, hsla steel. Qhov kev tsom xam tshwj xeeb yog raws li hauv qab no: Kev ua tau zoo xav tau ntawm alloy qauv txheej txheem:

(1) Lub zog siab: feem ntau, nws cov txiaj ntsig lub zog yog saum 300mpa.
(2) qhov siab tawv: Lub elongation yuav tsum yog 15% -20%, thiab chav tsev kub cuam tshuam nyuaj yog ntau dua 600KJ / M. Rau cov welded loj loj, cov pob txha siab dua cov pob txha tawv muaj zog kuj yuav tsum tau ua.
(3) Kev tsim txoj kev ua haujlwm zoo nkauj thiab kev ua kom txias.
(4) Qeeb txias txias txias txias txias.
(5) zoo corrosion tsis kam.
