                不銹鋼新牌號標準與舊牌號有什么不同

                國內鋼廠不銹鋼新牌號標準,與前一版本比較分析,新牌號與舊牌號標識上基本沒有太大變動,主要的化學元素標識都沒有變動,只有碳含量標識和個別鋼種里面化學元素發生變動:變壓器繞線機

                Domestic steel stainless steel new standards, compared with the previous version, the new brand and old brand logo on the basic does not have too big change, chemical elements the main logo is not change, only the carbon content identification and individual steel inside the chemical element change:

                1、碳(C)含量標識

                1, carbon (C) content identification

                1)舊牌號:Cr之前的數字表示碳的千份之幾的含量。如201(1Cr17Mn6Ni5N):碳(C)含量千分之一;2Cr13(420),7Cr17(440A),分別表示碳(C)含量千分之二和千分之七;如果C≤0.08%為低碳,變壓器繞線機標識為“0”,如(304)0Cr18Ni9;C≤0.03%為超低碳,標識為“00”,如00Cr17Ni14Mo2(316L)。

                1) the old brands: Cr before the digital representation of thousands of copies of some carbon content. Such as 201 (1Cr17Mn6Ni5N): carbon (C) content of 1/1000; 2Cr13 (420), 7Cr17 (440A), are expressed in terms of carbon (C) content of 2/1000 and 7/1000; if C ≤ 0.08% for low carbon, identified as "0", such as (304) 0Cr18Ni9; C ≤ 0.03% for ultra low carbon, identified as "00", such as 00Cr17Ni14Mo2 (316L).

                2)新牌號:Cr之前的數字表示碳(C)的萬分之幾的含量。如201牌號為12Cr17Mn6Ni5N,表示碳(C)含量萬分之十二(0.12%);304牌號為06Cr19Ni10,表示碳(C)含量萬分之六(0.06%);316L牌號為022Cr17Ni12Mo2,表示碳(C)含量萬分之二點二(0.022%)。其它標識基本不變。

                2) new grade: Cr before the digital representation of carbon (C) of the very few content. Such as 201 grades for the 12Cr17Mn6Ni5N, said carbon (C) content of 12/10000 (0.12%); 304 grades for the 06Cr19Ni10, said carbon (C) content of 6/10000 (0.06%); the 316L brand 022Cr17Ni12Mo2, said carbon (C) content of 2/10000. Two (0.022%). Other identification basically unchanged.

                新牌號中碳(C)含量較之以前更加明確,對產品生產技術也有了更高的要求。

                A new type of carbon (C) content than the previous more clear, the production technology, there are higher requirements.
