Discovery thiab Early Applications
Stainless hlau tau tshwm sim nyob rau hauv thaum ntxov 20th caug xyoo, tshwj xeeb tshaj yog nyob rau hauv 1913, los ntawm Harry Brearley, ib tug British metallurgist. Brearley pib nrhiav los tsim cov hlau tiv thaiv corrosion rau cov phom phom tab sis xaus nrog cov khoom siv nrog ntau daim ntawv thov. Nyob rau hauv nws thaum ntxov xyoo, stainless hlau yog feem ntau siv rau cutlery. Nws cov khoom tiv thaiv corrosive ua rau nws zoo tagnrho rau cov tais diav uas xav tau los tiv thaiv kev ntxhua khaub ncaws thiab raug rau ntau yam khoom noj.
Raws li lub xyoo pua 20th tau nce mus, cov ntawv thov ntawm stainless hlau nthuav dav. Nws tau tsim cov khoom siv tub rog, dav hlau, thiab cov nkoj tub rog thaum Tsov Rog Ntiaj Teb Zaum II. Nws lub zog tensile siab, xeb kuj, thiab dav dav ua rau nws tseem ceeb hauv cov ntsiab lus no.
Evolution ntawm nws siv nyob rau hauv Piping Systems
Stainless hlau kev siv hauv cov kav dej tau pib nce lub zog hauv lub sijhawm tom qab tsov rog. Thaum xub thawj, nws tau siv dav hauv kev siv tub rog vim nws tsis kam, tshwj xeeb tshaj yog nyob rau hauv cov dej ntsev. Thaum kawg, nws cov nqi hluav taws xob tau lees paub hauv pej xeem kev lag luam thiab.
Los ntawm xyoo 1960 thiab 1970s, cov kav hlau tsis muaj steel tau dhau los ua ntau dua hauv kev lag luam thiab kev lag luam. Nws pib hloov cov khoom xws li tooj liab thiab galvanized hlau hauv cov kav dej. Raws li kev lag luam hloov zuj zus, cov kev qhia tshwj xeeb thiab kev faib tawm ntawm cov kav hlau stainless kom haum rau ntau yam kev siv, xws li cov chaw ua tshuaj, cov chaw kho dej, thiab cov thev naus laus zis zoo li kev tsim khoom semiconductor.
Nyob rau hauv cov roj thiab roj sector, lub siab-siab tsis kam thiab durability ntawm tej yam stainless steel kav ua rau lawv zoo tagnrho rau thauj cov roj crude thiab natural gas. Hauv kev lag luam zaub mov thiab dej haus, cov khoom siv tiv thaiv corrosion thiab muaj peev xwm tswj tau purity ua rau nws cov khoom ntawm kev xaiv rau cov txheej txheem uas yuav tsum tau nruj tu cev.
