1.      首先要了解What"s Stainless Steel?
    在空气中或化学腐蚀介质中能够抵抗腐蚀的一种高合金钢,不锈钢是具有美观的表面和耐腐蚀性能好,不必经过镀色等表面处理,而发挥不锈钢所固有的表面性能,使用于多方面的钢铁的一种,通常称为不锈钢。(It was used to make products that need to be resistant to corrosion or oxidation.)代表性能的有13铬钢,18-铬镍钢等高合金钢。
从金相学角度分析,因为不锈钢含有铬而使表面形成很薄的铬膜,这个膜隔离开与钢内侵入的氧气起耐腐蚀的作用。
    为了保持不锈钢所固有的耐腐蚀性,钢必须含有12%以上的铬。
2.      美国AISI/ ASTM:430;UNS:S43000;日本SUS430 是同种型号的钢,只是各个国家不同的表示方法。相当于中国的1Cr17。故,1Cr17=TYPE 430≠2Cr13,它们是两种不同的材料。而2Cr13 是中国的表示方法,相当于国外的TYPE 420。

3.      不锈钢和耐热钢的牌号表示方法不锈钢和耐热钢牌号采用标准规定的合金元素符号和阿拉伯数字表示,为切削不锈钢、易切削耐热钢在牌号头部加"Y"。
一般用一位阿拉伯数字表示平均含碳量(以千分之几计);当平均含碳量≥1.00%时,用两位阿拉伯数字表示;当含碳量上限<0.10%时,以"0"表示含碳量;当含碳量上限≤0.03%,>0.01%时(超低碳),以"03"表示含碳量;当含碳量上限(≤0.01%时极低碳),以"01"表示含碳量。含碳量没有规定下限时,采用阿拉伯数字表示含碳量的上限数字。
合金元素含量表示方法同合金结构钢。例如:平均含碳量为0.20%,含铬量为13%的不锈钢,其牌号表示为"2Cr13";含碳量上限为0.08%,平均含铬量为18%,含镍量为9%的铬镍不锈钢,其牌号表示为"0Cr18Ni9";含碳量上限为0.12%,平均含铬量为17%的加硫易切削铬不锈钢,其牌号表示为"Y1Cr17";平均含碳量为1.10%,含铬量为17%的高碳铬不锈钢,其牌号表示为"11Cr7";含碳量上限为0.03%,平均含铬量为19%,含镍量为10%的超低碳不锈钢,其牌号表示为"03Cr19Ni10";含碳量上限为0.01%,平均含铬量为19%,含镍量为11%的极低碳不锈钢,其牌号表示为"01Cr19Ni11"。

4.      13/0 Stainless Steel,"13-0"、"18-0"、"18-8" 不锈钢的三种代号,代号前面的数字表示铬含量,后面的数字则代表镍含量。13/0 Stainless Steel ,指13%铬含量,Steel grade. EN 10088-3/95. QT 700. 1.4021. ASTM A276. (Type 420)。

5.      延伸:The 18/8 and 18/10 designations are older terms, and refer to the amount of chromium and nickel alloyed with the iron, to comprise the stainless steel. The 18/8 name has been pretty much replaced, in the States at least, by several other designations. 301 stainless steel has 16-18% Cr, and 6-8% Ni 302 stainless steel has 17-19% Cr, and 8-10% Ni 304 stainless steel has 18-20% Cr, and 8-10.5% Ni That may explain your difficulty in finding information on these alloys. Similarly, 18/10 is usually referred to as 316 stainless steel, with 16-18% Cr, 10-14% Ni, and also 2-3% molybdenum, which greatly increases the resistance to pitting corrosion in seawater. Good stuff, that moly.
