A182 F44 yog dab tsi?

A182 F44 yog qib khoom siv rau hom austenitic stainless hlau uas tseem hu ua 6 Moly lossis 6 Molybdenum. Nws yog cov khoom siv ua haujlwm siab uas muaj 6 feem pua ​​​​molybdenum thiab muaj kev tiv thaiv zoo rau corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav uas muaj chlorides thiab acids. Lub npe A182 F44 yog hais txog ASTM specification A182 forged los yog dov alloy thiabstainless hlau yeeb nkab flanges, forged fittings, thiab li qub thiab qhov chaw rau kev pabcuam kub. A182 F44 feem ntau yog siv rau hauv cov roj thiab roj, kev ua tshuaj lom neeg, thiab cov ntaub ntawv thiab cov ntawv lag luam, thiab lwm yam, rau cov ntawv thov uas xav tau lub zog siab, toughness, thiab corrosion kuj.

A182 F44 S31254 yog cov hlau tsis muaj hlau austenitic. UNS S31254 F44 muaj qhov zoo tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav uas muaj halides xws li chloride, ua W.Nr. 1.4547 haum rau kev siv tshuaj thiab petrochemical kev lag luam, roj thiab roj, thiab kev siv dej hiav txwv.

A182 F44 S31254 muaj lub zog txhua yam, zoo weldability, thiab zoo heev tsis kam rau pitting, crevice, thiab kev nyuaj siab corrosion cracking. 254 SMO muaj cov qib siab ntawm chromium, molybdenum, thiab nitrogen, uas muab nws cov khoom tshwj xeeb corrosion kuj.

ASTM A182 F44 UNS S31254 feem ntau yog siv rau ntau yam kev siv, suav nrog:

1. Thaum tshav kub kub exchangers, siab hlab ntsha, thiab piping systems nyob rau hauv tshuaj thiab petrochemical ua cov nroj tsuag.

2. Offshore roj thiab roj kev lag luam Cheebtsam, xws li pipelines, risers, thiab subsea khoom.

3. Seawater desalination nroj tsuag, uas yuav tsum tau cov ntaub ntawv uas muaj corrosion kuj.

4. Pulp thiab ntawv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv bleach nroj tsuag thiab digesters, qhov uas muaj corrosion kuj yog qhov tseem ceeb.

5. Cov khoom siv ua zaub mov, qhov twg cov khoom siv tiv thaiv corrosion yog tsim nyog los tswj kev huv.
