Ntawm 347 Stainless Hlau Pipes

Mechanical Properties ntawm 347 Stainless hlau kav

Chav ntsuas kub Tensile Properties

Yam tsawg kawg nkaus txhua yam khoom ntawm cov stabilized Alloys 321 thiab 347 chromium-nickel qib nyob rau hauv lub annealed mob (20000F [10930C], cua txias) yog qhia nyob rau hauv lub rooj.

elevated Temperature Tensile Properties

Qhov ntsuas kub siab txhua yam khoom siv rau Alloys 321 thiab 347 daim ntawv / strip yog qhia hauv qab no. Lub zog ntawm cov stabilized alloys no txawv tshaj qhov uas tsis yog-stabilized 304 alloys ntawm qhov kub thiab txias ntawm 10000F (5380C) thiab siab dua.

High carbon Alloys 321H thiab 347H (UNS32109 thiab S34700, feem) muaj zog dua ntawm qhov kub siab tshaj 10000F (5370C). ASME qhov siab tshaj plaws tsim cov ntaub ntawv kev ntxhov siab rau Alloy 347H qhia txog lub zog siab dua ntawm qib no piv rau qib qis carbon Alloy 347. Alloy 321H tsis raug tso cai rau Tshooj VIII daim ntawv thov thiab txwv rau 8000F (4270C) siv qhov kub thiab txias rau Tshooj III daim ntawv thov.
