ASTM 240 321 Daim ntawv 5 hli Thickness

Stainless hlau muaj nyob rau hauv ntau qib. Ib qib zoo li no yog 321 uas ruaj khov austenitic hlau thiab muaj kev tiv thaiv zoo rau kev xeb. ASTM 240 321 Daim ntawv yog ib qho ntawm cov khoom tsim los ntawm qib no. 321 Stainless Hlau Phaj qhia tau zoo heev tiv thaiv intergranular corrosion thaum raug chromium carbide nag lossis daus kub ntawm 800 degrees F mus rau 1500 Degrees F. cov khoom siv hauv Werkstoff 1.4541 Clad Phaj kuj tseem tiv taus oxidation ntawm 1500 degrees C. nws kuj qhia ntau dua kev ntxhov siab rau rupture. thiab creep resistant zog nrog rau toughness ntawm tsawg kub.

ASTM A240 Hom 321 Coil Supplis raws li lawv tuaj yeem ua tau yooj yim welded thiab fabricated. Kev kho cua sov tsis cuam tshuam rau cov nplooj ntawv. Li no 321 Plate Cold Rolled Phaj yog txias ua hauj lwm kom tau qhov xav tau hardness. SS 321H Phaj yog qhov zoo tshaj plaws tsim los siv nyob rau hauv thaj tsam ntawm 1500 degrees F txog 1800 degrees F qhov twg qib 304 ib txwm muaj kev cuam tshuam rau kev tawm tsam intergranular. 321 Stainless Hlau Kub Rolled Sheet tuaj yeem siv rau ntawm qhov kub thiab txias hauv diluted organic acid. ASTM 240 321 Daim ntawv tseem tuaj yeem tiv thaiv cov hydrocarbons thiab polythionic acid kev nyuaj siab corrosion tawg. Cov SS 321H Coils no tsis tsim zoo hauv sulfuric acid thiab chloride daws.
