ASTM A268 TP410 zanglamaydigan po'lat quvur
Standart martensitik zanglamaydigan po'latlar quyidagilardir: 410, 414, 416, 416 (Se), 420, 431, 440A, 440B va 440C turlari, ular magnitdir; bu po'latlar korroziyaga chidamliligi 11,5 dan 18 foizgacha bo'lgan "xrom" dan kelib chiqadi va xrom miqdori qanchalik yuqori bo'lsa, uglerod miqdori shunchalik yuqori bo'lishini ta'minlash uchun xrom miqdori qanchalik yuqori bo'lsa, uglerod miqdori shunchalik yuqori bo'ladi. issiqlik bilan ishlov berish jarayonida martensit hosil bo'lishini ta'minlash.
