Ce este S\u00e2rma Moale Neagr\u0103?<\/span><\/h2>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n

S\u00e2rma moale neagr\u0103 este ob\u021binut\u0103 prin procesul de trefilare a s\u00e2rmei tari, urmat de un tratament termic specific (recoacere). Acest proces elimin\u0103 tensiunile interne ale o\u021belului, conferindu-i o maleabilitate excep\u021bional\u0103. Nu beneficiaz\u0103 de o acoperire protectoare, de unde \u0219i culoarea specific\u0103, \u00eenchis\u0103.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n

S\u00e2rma zincat\u0103 parcurge un proces suplimentar fa\u021b\u0103 de cea neagr\u0103: galvanizarea. Prin scufundarea o\u021belului \u00eentr-o baie de zinc topit, suprafa\u021ba s\u00e2rmei este acoperit\u0103 cu un strat protector care previne oxidarea fierului.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n
