304H Austenitic Stainless Hlau - Siab -Tsub Zog-Optimized Alloy

Kev piav qhia

304H yog qhov siab -carbon variant ntawm 304, tailored rau elevated - kub daim ntawv thov uas xav tau kev txhim kho creep resistance thiab mechanical stability. Nrog rau cov pa roj carbon ntau ntawm 0.04-0.10%, nws ua tau zoo tshaj tus qauv 304 thiab 304L nyob rau hauv lub sijhawm ntev- kev pabcuam ntawm qhov kub siab tshaj 500 degree, qhov qis dua - cov pa roj carbon monoxide tej zaum yuav ua rau muaj zog degradation. Nws tuav tib cov qauv austenitic thiab kev tiv thaiv corrosion raws li 304, seem tsis yog - sib nqus ntawm chav tsev kub, thaum muab kev txhim kho siab - kub tensile thiab creep zog. Tsis zoo li 304 thiab 304L, 304H tau tsim tshwj xeeb rau qhov chaw kub kub, ua rau nws yog ib qho tseem ceeb hauv kev tsim hluav taws xob, boiler, thiab kev siv cua sov uas cov khoom siv yuav tsum tiv taus thermal kev nyuaj siab yam tsis muaj kev cuam tshuam kev ncaj ncees.

Chemical Composition (wt%)

C: 0.04-0.10, Cr: 18.00-20.00, Ni: 8.00-11.00, Mn Tsawg dua lossis sib npaug 2.00, Si Less dua lossis sib npaug 1.00, P Tsawg dua lossis sib npaug 0.045, S Tsawg dua lossis sib npaug 0.030

Mechanical Properties

Tensile Strength Ntau dua los yog sib npaug rau 520 MPa, Yield Strength Ntau dua los yog sib npaug rau 205 MPa, Elongation Ntau dua lossis sib npaug li 40%, Hardness Tsawg dua lossis sib npaug rau 200 HB

Qhov zoo

Superior siab -kub creep resistance vs. 304/304L; zoo heev oxidation tsis kam ntawm siab kub; tsis yog-magnetic; zoo weldability; ruaj khov kev ua haujlwm ntawm 500℃+; haum rau siab - qhov kub thiab txias siab Cheebtsam.

Daim ntawv thov

Boiler tubes, siab -kub kav, cua kub exchangers, lub cub tawg Cheebtsam, cov khoom tsim hluav taws xob, thiab muaj cua sov tshuab uas yuav tsum tau ntev - lub sij hawm siab - kub stability.

Qib sib npaug

AISI 304H, UNS S30409, EN 1.4306, GB 07Cr19Ni10, SUS304H
