304L stainless steel. In order to solve the serious intergranular corrosion tendency of 304 stainless steel due to the precipitation of Cr23C6 under some conditions, the ultra-low carbon austenitic stainless steel was developed, and its intergranular corrosion resistance of the sensitized state was significantly better than 304 stainless steel. In addition to slightly lower strength, other performance with 321 stainless steel, mainly used for welding and can not be solution treatment of corrosion resistance equipment and parts, can be used to manufacture all kinds of instrument body.

304 stainless steel (industry nickname: 18/8 stainless steel [1]) is a common stainless steel material, density of 7.93 g/cm3, high temperature resistance of 800℃, in order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% nickel content.

It has the characteristics of good processing performance, high toughness, widely used in industry and furniture decoration industry and food and medical industry, as well as the production of good comprehensive performance (corrosion resistance and molding) of equipment and parts

For 304 stainless steel, the Ni element in its composition is very important, directly determines the corrosion resistance of 304 stainless steel and its value.

The most important elements in 304 are Ni and Cr, but they are not limited to them. Specific requirements are specified in the product standard. The common determination of the industry that as long as the Ni content is greater than 8%, Cr content is greater than 18%, can be considered 304 stainless steel. This is why the industry will call this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards for 304 have very clear provisions, and these product standards for different shapes of stainless steel and some differences. Below are some common product standards and tests.

To determine whether a material is 304 stainless steel, must meet the requirements of every element in the product standards, as long as there is a does not meet, it can not be called 304 stainless steel.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second".
