304 stainless steel: 0Cr18Ni9 (0Cr19Ni9) 06Cr19Ni9 S30408

Chemical composition :C: ≤0.08, Si: ≤1.0 Mn: ≤2.0, Cr: 18.0 ~ 20.0, Ni: 8.0 ~ 10.5, S: ≤0.03, P: ≤ 0.035N ≤0.1.

With 304L

Nature of the national standard

Tensile strength (Mpa) 520

Yield strength (Mpa) 205-210

Elongation (%) 40%

Hardness HB187 HRB90 HV200

304 stainless steel density 7.93 g/cm3 austenitic stainless steel generally use this value 304 chromium content (%) 17.00-19.00, nickel content (%) 8.00-10.00, 304 is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel

304 stainless steel is a universal stainless steel material, rust resistance is better than 200 series of stainless steel material. High temperature resistance is also better.

304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance.

For oxidizing acid, in the experiment: concentration ≤65% of the boiling temperature of nitric acid, 304 stainless steel has a strong corrosion resistance. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.

General features
The surface of 304 stainless steel plate is beautiful and the possibility of diversification

Good corrosion resistance, durability and corrosion resistance than ordinary steel

High strength, so the possibility of use of thin plate

High temperature oxidation resistance and high strength, so it can resist fire

Normal temperature processing, that is, easy plastic processing

Because do not need surface treatment, so simple, simple maintenance

Clean, high finish

Good welding performance

And the difference between 316
The most commonly used two kinds of stainless steel 304,316 (or corresponding to Germany/European standard 1.4308,1.4408), 316 and 304 in the chemical composition of the most important difference is that 316 contains Mo, and it is generally recognized that 316 corrosion resistance is better, more corrosion resistance than 304 in high temperature environment. Therefore, in high temperature environment, engineers generally choose parts made of 316 material. But there is no absolute matter, in concentrated sulfuric acid environment, no matter how high the temperature is, do not use 316! This is gonna be a big deal. Those of you who study mechanics have studied threads, and remember MoS2, a dark, solid lubricant applied to prevent threads from biting at high temperatures, which leads to two conclusions: [1]Mo is indeed a high-temperature substance (know what crucible gold is melted in? Molybdenum crucible!) . [2] : Molybdenum reacts easily with high sulfur ions to form sulfide. So no stainless steel is super resistant to corrosion. After all, stainless steel is a piece of steel with more impurities (but those impurities are more resistant to corrosion than steel), and it can react with other substances.

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". Most of the time, we have comprehensive inspection and procurement to control the quality of finished products. We will have a professional inspection team to test each delivery of products.

Since its establishment, in line with the mission of "contributing high-quality products and services to the world" and the core values of "customer first, excellence, coexistence and win-win", we ensure that we can deeply cooperate with all our friends in the field of iron and steel, and win more affirmation and praise from the market and customers with its high-quality products, perfect product team and thoughtful service, I believe tomorrow will be better!
