317L Stainless Hlau Txheej txheem cej luam
317L yog molybdenum bearing, qis carbon cov ntsiab lus "L" qibaustenitic stainless hlauuas muab kev txhim kho corrosion ntau dua 304L thiab 316L stainless hlau. Cov pa roj carbon tsawg muab kev tiv thaiv rau rhiab heev thaum vuam thiab lwm yam txheej txheem thermal.
317L yog tsis sib nqus nyob rau hauv lub annealed mob tab sis tej zaum yuav ua me ntsis sib nqus raws li qhov tshwm sim ntawm vuam.
Corrosion Resistance
317L muaj corrosion kuj zoo heev nyob rau hauv ntau yam tshuaj, tshwj xeeb tshaj yog nyob rau hauv acidic chloride ib puag ncig xws li cov uas tau ntsib nyob rau hauv pulp thiab ntawv mills. Nce qib ntawm chromium, npib tsib xee thiab molybdenum piv rau 316L stainless hlau txhim khu kev tiv thaiv chloride pitting thiab dav corrosion. Tsis kam nce nrog molybdenum alloy cov ntsiab lus. 317L yog resistant rau sulfuric acid concentrations txog li 5 feem pua ntawm qhov kub thiab txias li 120 ° F (49 ° C). Thaum kub hauv qab 100 ° F (38 ° C) cov hlau no muaj kev tiv thaiv zoo heev rau cov kev daws teeb meem ntawm ntau dua concentration. Txawm li cas los xij, kev ntsuam xyuas kev pabcuam raug pom zoo kom suav txog qhov cuam tshuam ntawm kev ua haujlwm tshwj xeeb uas yuav cuam tshuam rau tus cwj pwm corrosion. Nyob rau hauv cov txheej txheem uas condensation ntawm sulfur-bearing gases tshwm sim, 317L yog ntau resistant mus tua nyob rau hauv lub point ntawm condensation tshaj li cov pa hlau alloy 316. Cov kua qaub concentration muaj ib tug cim muaj feem xyuam rau tus nqi ntawm kev tawm tsam nyob rau hauv xws li ib puag ncig thiab yuav tsum tau ua tib zoo txiav txim siab los ntawm kev pab. kuaj.

Vuam 317L
317L tau yooj yim welded los ntawm ntau yam ntawm cov txheej txheem vuam ib txwm (tshwj tsis yog oxyacetylene). AWS E317L / ER317L muab tub lim hlau lossis austenitic, qis carbon muab tub lim hlau nrog molybdenum cov ntsiab lus siab dua li ntawm 317L, lossis cov nickel-base muab tub lim hlau nrog cov ntsiab lus chromium thiab molybdenum txaus kom tshaj qhov corrosion kuj ntawm 317L yuav tsum tau siv los vuam 317L steel.
