SS 304 的含义是什么?
Type 304 stainless steel is a T 300 series austenitic stainless steel. It contains a minimum of 18% chromium and 8% nickel, and a maximum of 0.08% carbon. It is defined as a chromium-nickel austenitic alloy. Grade 304 is the standard "18/8" stainless steel you might see in pans and cooking tools.
SS316 和 SS304 有什么区别?
The main difference between 304 and 316 stainless steel is the chemical composition, 316 contains a large amount of molybdenum; typically 2 to 3% by weight, while 304 has only trace amounts. Higher molybdenum content results in higher corrosion resistance of grade 316.
304 不锈钢质量好吗?
Both steels are durable and have excellent corrosion and rust resistance. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world because of its corrosion resistance.
如何辨别不锈钢是否为 304?
如果要对 SS 进行抽查,只需从原材料中随意取一块进行火花测试即可。用磨床磨一磨,如果火花呈橙红色,很稀薄,飞溅不多,那就是 SS304。如果火花是黄色的,很粗,飞得很远,那就是 SS 202。
