Qhov tseem ceeb sib txawv & zoo sib xws:
Khoom siv: Ob leeg yog ASTM A203 npib tsib xee- alloy steel daim hlau tsim rau cov hlab ntsha siab.
Nickel Cov ntsiab lus:
Qib B: Muaj kwv yees li 2.25% Nickel (2% Ni hlau).
Qib E: Muaj kwv yees li 3.25% Nickel (3% Ni hlau).
Daim ntawv thov: Ob leeg ua haujlwm rau siab -kub siab ntawm lub nkoj kev lag luam, tshwj xeeb tshaj yog rau cov roj, roj, thiab tshuaj siv tshuaj, tab sis Qib E cov ntsiab lus ntau dua nickel muab qhov zoo dua qis -kub toughness.
Mechanical Properties: Lawv sib koom cov khoom siv kho tshuab zoo sib xws, tab sis Qib E cov ntsiab lus zoo dua rau cov kev pabcuam txias dua.
Kev kho cua sov: Ob qib feem ntau xav tau kev kho cua sov kom zoo.
