FAQ
Q.Yog SA240 TP316L zoo ib yam li ASTM A240 316L?
A.Yog, SA240 TP316L thiab ASTM A240 316L feem ntau suav tias yog sib npaug ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Lawv yog ob qho tib si qis -carbon, chromium-nickel austenitic stainless hlau tsim los tiv thaiv corrosion. Qhov sib txawv tseem ceeb yog SA240 yog ASME (American Society of Mechanical Engineers) tus qauv, thaum A240 yog tus qauv ASTM.
Q.Dab tsi yog qhov txawv ntawm 316L thiab 304 stainless hlau?
A. Qhov sib txawv tseem ceeb yog tias 316L muaj 2-3% molybdenum thiab Tsawg dua lossis sib npaug ntawm 0.03% carbon, muab nws ua haujlwm siab dua rau pitting thiab crevice corrosion tshaj 304 stainless hlau, uas tsis muaj molybdenum thiab txog li 0.08% carbon.
Q. Puas yog TP316L haum rau kev siv dej hiav txwv?
A. Yog, TP316L (UNS S31603) yog qhov tsim nyog rau kev siv dej hiav txwv, feem ntau hu ua "marine qib" stainless hlau.
