Cov khoom siv dab tsi yog A479 S31803 tuav?

ASTM A479 khoom yog dab tsi?

ASTM A479 / A479M Standard Specification for Stainless Steel Bars and Shapes for Use in Boilers and Other Pressure Vessels is a key standard for stainless steel cov ntaub ntawv siv nyob rau hauv boilers thiab siab hlab ntsha, npog ntau yam (austenitic, duplex, thiab lwm yam) nyob rau hauv bar (rounds, squares, hexagons) thiab cov duab (lub kaum sab xis, cov ntaub ntawv uas siv nyob rau hauv lub boilers thiab siab hlab ntsha, npog ntau yam (austenitic, duplex, thiab lwm yam)) nyob rau hauv bar (rounds, squares, hexagons) thiab cov duab (lub kaum sab xis, cov ntaub ntawv uas siv nyob rau hauv lub boilers thiab siab hlab ntsha), npog ntau yam (austenitic, duplex, thiab lwm yam). kev kho mob, thiab kev sim rau kev siv nyab xeeb hauv kev siv siab - siab.

 

Cov khoom siv dab tsi yog A479 S31803 tuav?

ASTM A479 S31803 stainless hlau tuav yog tsim los ntawm duplex stainless hlau, feem ntau hu ua 2205 duplex stainless hlau. Lawv muaj lub zog siab, zoo heev corrosion kuj (tshwj xeeb tshaj yog tiv thaiv chloride corrosion thiab pitting), thiab weldability zoo. Lawv nquag siv nyob rau hauv tshuaj, roj thiab roj, thiab marine ib puag ncig, thiab yog haum rau siv raws li tuav thiab profiles nyob rau hauv boilers thiab siab hlab ntsha. Lawv cov khoom zoo ib yam li ASTM A182 F51.
