Wuxi 304 stainless steel 304 stainless steel is a versatile stainless steel material, anti-rust performance is stronger than the 200-series stainless steel. The high temperature is also more general use temperature limit is less than 650 ° C. 304 stainless stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. Oxidizing acids derived experiment: the nitrate concentration ≤ 65% below the boiling temperature, 304 stainless steel has a strong anti-corrosive. Also has good corrosion resistance to alkali solution and most organic and inorganic acids. 304 stainless steel is a common stainless steel, also known as 18/8 stainless steel in the industry. Its corrosion resistance superior to 430 stainless steel, but the price surpasses 316 stainless steel cheaper, it is widely used in the life, for example: high-grade stainless steel cutlery, outdoor railings. Although such stainless steel in the country is very common, but this title "304 stainless steel" from the United States. Many people think that the 304 stainless steel is called a model in Japan, but the strict sense of the terms, Japan formally known as "SUS304 304 stainless steel. 304 is a versatile stainless steel, it is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 16% chromium, a nickel content of more than 8%. 304 stainless steel is produced in accordance with the American ASTM standard stainless steel grades. 304 is equivalent to of 0Cr18Ni9 [According to GB / T 20878-2007 now change 06Cr19Ni10】 stainless steel. For 304 stainless steel is a very important parameter directly determines its corrosion resistance, and also determine its value. The 304 most important element is Ni, Cr, but it is not limited to these two elements. The specific requirements of product standard requirements. The industry common judgment situation think that as long as the Ni content of more than 8% Cr content greater than 18%, that is 304 stainless steel. This is why the industry will kind of stainless steel called 18/8 stainless steel. In fact, the product standard 304 has very clear provisions of these product standards for different shapes of stainless steel, there are some differences. Here are some common product standards and testing. http://www.wybxg.com/
