Biphase Stainless hlau
Kub Kub Alloy
◆ F51 (31803) yog cov khoom siv duplex stainless hlau ntau tshaj plaws, feem ntau yog siv hauv cov roj qaub thiab roj zoo ntau lawm, hauv cov roj refining, tshuaj, chiv, petrochemical thiab lwm yam kev lag luam, rau kev tsim cov cua kub exchangers, condensing coolers, thiab lwm yam. uas yog nquag rau pitting corrosion thiab kev nyuaj siab corrosion ntawm cov khoom siv siab. Hloov 304L, 316L austenitic stainless hlau.
◆ F53 (S32750) yog ib tug super duplex stainless hlau nrog nitrogen ntxiv, uas yog tsuas yog siv nyob rau hauv tshuaj, petrochemical thiab marine khoom uas yuav tsum tau tshwj xeeb lub zog thiab corrosion kuj.
◆ F55 (S32760) yog ib qho super duplex stainless hlau nrog lub zog siab, siab tiv thaiv chloride hauv zos corrosion thiab kev ntxhov siab corrosion, thiab weldable.
◆329 (S32900) muaj oxidation zoo, corrosion kuj, siab zog, thiab yog haum rau ib puag ncig xws li seawater corrosion kuj.
◆ A4 steel (0Cr17Mn13Mo2N) yog ob-theem steel, thiab nws cov corrosion kuj zoo dua li cov feem ntau siv austenitic steel nrog Mo cov ntsiab lus ntawm 2% -3%. Nws tuaj yeem siv rau cov tshuaj me me, cov khoom siv urea tag nrho, thiab lwm yam.
◆ S31050 muaj kev tiv thaiv siab rau chloride kev nyuaj siab corrosion cracking, zoo heev tiv thaiv pitting corrosion thiab crevice corrosion.
◆ U3 muaj cov khoom tiv thaiv thiab tiv thaiv corrosion, thiab feem ntau yog siv los ua cov cores valve, lub rooj zaum valve thiab lwm yam khoom siv hauv lub valve.
◆ HD yog dav siv nyob rau hauv kev lag luam hluav taws xob, kev lag luam photoelectric, kev lag luam petrochemical, kev lag luam tsheb thiab lwm yam ceev tswj hluav taws xob roj zoo twj.
◆ C4 yog tsim rau loj-scale ntsug mixers, mixers, mixers, kab rov tav mixers thiab lwm yam machinery industries.
◆DS-2 muaj corrosion kuj nyob rau hauv high kub concentrated sulfuric acid, thiab yog haum rau machinery kev lag luam nyob rau hauv high kub concentrated sulfuric acid kev lag luam.
