AISI 416<\/strong>, AISI 410<\/strong>‘un tala\u015fl\u0131 imalat i\u00e7in k\u00fck\u00fcrt eklenmi\u015f versiyonudur. Krom band\u0131 hemen hemen ayn\u0131d\u0131r, ikisi de su verilerek sertle\u015fir.

AISI 416’da k\u00fck\u00fcrt %0,15 – 0,35<\/strong> aral\u0131\u011f\u0131ndad\u0131r ve bu bir minimumdur<\/em>. AISI 410’da ise k\u00fck\u00fcrt bir safs\u0131zl\u0131kt\u0131r ve tavan\u0131 max %0,030<\/strong>‘dur. Yani aradaki fark be\u015f kat\u0131n \u00fczerindedir. Sahada en s\u0131k g\u00f6r\u00fclen hata, bu aral\u0131\u011f\u0131 tavan sanmakt\u0131r: %0,02 k\u00fck\u00fcrt g\u00f6steren bir sertifika 416 de\u011fildir.<\/strong><\/p>\n

Tek bir oran vermiyoruz — kurulu\u015flar farkl\u0131 referans taban\u0131 kullan\u0131yor. Kesin olan s\u0131ralamad\u0131r: 416, 410’dan belirgin \u015fekilde daha kolay i\u015flenir.<\/p>\n

Bedeli iki yerden \u00f6denir<\/h3>\n

Kaynak.<\/strong> BSSA, Aalco, Righton Blackburns, Thames Stockholders ve Outokumpu — be\u015f ayr\u0131 kurulu\u015f — 416’n\u0131n kaynak kabiliyetini zay\u0131f buluyor ve kaynakl\u0131 imalat i\u00e7in \u00f6nermiyor. Sebep, k\u00fck\u00fcrd\u00fcn s\u0131cak \u00e7atlama e\u011filimini art\u0131rmas\u0131d\u0131r.
