AISI 410<\/strong> ve AISI 420<\/strong>, martenzitik paslanmaz \u00e7eliklerin iki temel kalitesidir. \u00d6stenitik 304\/316 ailesinin aksine bu \u00e7elikler sertle\u015ftirilebilir<\/strong> ve manyetiktir<\/strong>. \u0130kisi de yakla\u015f\u0131k %12\u201314 krom i\u00e7erir; aradaki fark karbondad\u0131r.<\/p>\n

Karbon oran\u0131, ula\u015f\u0131labilen sertli\u011fi belirler<\/h3>\n

Martenzitik paslanmazlarda sertlik do\u011frudan karbondan gelir. AISI 410’da karbon max %0,15<\/strong>, AISI 420’de %0,16 \u2013 0,25<\/strong>‘dir. Krom da 420’de bir miktar y\u00fcksektir (%12\u201314’e kar\u015f\u0131 %11,5\u201313,5).<\/p>\n

Bu fark, sertle\u015ftirme sonras\u0131 ula\u015f\u0131lan de\u011ferlere yans\u0131r.
