Overview: 304 stainless steel is a common material density of 7.93 g / cm3, the industry also called 18/8 stainless steel. High temperature of 800 degrees, with good workability, high toughness, which is widely used in industrial and medical furniture industry and the food industry. The common market, marking methods have 0Cr18Ni9, SUS304, which generally represents 0Cr19Ni10 GB standard production, S30408 ??generally represents ASTM standard production, SUS 304 represents the Japanese standard standard. 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 18% chromium, 8% nickel content. 304 stainless steel is a grade produced in accordance with the ASTM standard stainless steel.

Corrosion in the atmosphere, if the industrial atmosphere or in heavily contaminated areas, the need for timely clean to avoid corrosion. Suitable for use in food processing, storage and transport. It has good processing properties and weldability. Plate heat exchanger, bellows, household goods (1,2 tableware, cabinets, indoor pipes, water heaters, boilers, bath), auto parts (windshield wipers, muffler, mold products), medical equipment, building materials, chemical, food industry , agriculture, ship parts, and so on. 304 stainless steel is a nationally recognized food-grade stainless steel. Most of the requirements is to maintain long-term building of the original appearance. In determining when to choose the type of stainless steel, the main consideration is the aesthetic standards required, corrosive and clean up the system to use the location of the atmosphere. However, a growing number of other applications simply seek integrity or impermeability structure. For example, industrial building roof and side walls. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean may be. The use of 304 stainless steel effect in dry indoor environment is quite good. However, in rural and urban in order to maintain their appearance in the outdoors, they need frequent cleaning. In heavily polluted industrial areas and coastal areas, the surface will be very dirty, and even rust. But to get an outdoor environment aesthetic effect, it requires the use of nickel-containing stainless steel. Therefore, 304 stainless steel is widely used in curtain wall, side walls, roof and other construction purposes, but in severe erosion of industrial or marine atmosphere, preferably 316 stainless steel. Stainless steel sliding door, it has been fully aware of the use of stainless steel in structural applications superiority. There are several design criteria included in the 304 and 316 stainless steel. Because "duplex" 2205 Yiba good atmospheric corrosion resistance and high tensile strength and proof strength blend, so European guidelines also include the steel. Product shape Indeed, stainless steel is the standard all-metal manufacturing shapes and sizes, and there are many special shapes. The most commonly used product is made of sheet and strip, and plate production with special products, for example, the production of hot-rolled structural steel and extruded structural sections. But there are round, oval, square, rectangular and hexagonal welded or seamless steel tubes and other forms of products, including profiles, rods, wire and castings. 304, the preferred Kun-hong; 304 steel, Jiang Su Kunhong; 304 material, Kun-hong metal; 304 bar, Kun-hong die steel; 304 rod all Kun-hong; 304 Roundwood, wholesale Kun-hong; 304 bar, 304 bar preferred Kun-hong;; Kun-hong steel 304 bars, Kunshan Kun-hong; 304 steel, Kun-hong metal; 304 plates, Kun-hong die steel; 304 sheets, all in Kun-hong; 304 forging round, Kun-hong wholesale ; 304 forging plate, Kun-hong steel; 304 forging, the preferred Kun-hong; 304 flat, Jiang Su Kunhong; 304 steel, Kun-hong metal; 304 die steel, tool steel Kun-hong; 304 special steel, all in Kun-hong; 304 mold steel, Kun-hong wholesale; 304 mold material, Kun-hong steel; 304 chemical composition, the preferred Kun-hong; 304 heat treatment process, Kunshan Kun-hong; 304 mechanical and physical properties, Kun-hong metal; 304 wholesale price, Kun-hong die steel; 304 wholesale, all in Kun-hong; 304 price, Kun-hong wholesale; 304 stainless steel rods, Kun-hong steel; 304 stainless steel, the preferred Kun-hong; 304 stainless iron, Jiang Su Kunhong; 304 stainless steel, Kun-hong metal; Baosteel 304 Queensland Macro mold steel; long steel 304 all Kun-hong; Donte 304 Kun-hong wholesale; Changcheng Special Steel 304 Kun-hong; Baosteel 304 Kun-hong die steel; long steel 304 all Kun-hong; Donte 304 Kun-hong wholesale; Great Wall Steel 304 Kun-hong steel; Dongbei Special Steel 304 preferred Kun-hong; Jiang Su Kunhong 304; 304 steel Wuchang, Kun-hong metal; 304 US imports, Kun-hong die steel; 304 US stainless steel, all in Kun-hong; 304 United States stainless iron, Kun-hong steel. 304 stainless steel corrosion-resistant stainless steel iron 304 | rod Category: Car light round, pull light round, black fur round 304 | Plate Category: Machine rolling plate, forging plate, forging plate, rolling plate 304 [Baoding, Cangzhou, Chengde, Liaoning Zhengzhou, Hangzhou, Dalian, Fushun Dandong Lishui Fuxin quality assurance] 304 [Jingjiang special treasure Jiangyin Yixing Wuxi, Xuzhou, Yancheng Dongtai Sheyang Xiangshui Jiaxing Cixi quality assurance] 304 [Weifang, Yantai Zaozhuang Lishui Ma On Shan Shanghai, Kunshan, Zhangjiagang, Lianyungang Jingdezhen quality assurance] 304 [ Huangshan Lu'an, Huainan Xuancheng Jiangyan roof Wenling Quzhou Yongkang Dongying Yantai Baoying quality assurance] 304 [Zibo, Weifang, Weihai, Qingdao Sunshine Jiaxing Deqing Shanghai Zhenhai, Taizhou Taian Yixing 304 [quality assurance] Xianju Yuhuan Yueqing Pingyang Cangnan Ryan Yongjia Zhoushan Xiamen Hefei, Nanjing, 304 [quality assurance] Jiangshan Shaoxing Xinchang Shengzhou Shangyu Zhuji Huangyan Linhai Bridge Changshu Yuyao 304 [quality assurance] Jinyun Longquan Fenghua Ningbo Beilun, Cixi, Yuyao Jiang Taizhou western suburbs of Xi'an] Xiangshan quality assurance Kun-hong Metal: Baoding, Hebei, Liaoning, Dalian Dandong Zhengzhou 304 | Kun Wang Kun-hong Metal: Taiyuan Huangyan Wuhu Hangzhou Lishui 304 | Kun Wang Kun-hong Metal: Shandong Dezhou, Dongying, Jinan, Laiwu, Liaocheng 304 | Kun Wang Kun-hong Metal: Hanzhong, Shaanxi Xi'an Yingkou Shenyang Yangzhou 304 | Kun Wang Kun-hong Metal: Hebi, Luoyang Xinxiang Xinyang Yancheng Laiwu 304 | Kun Wang Kun-hong Metal: Chuzhou, Anhui Wuhu Huzhou, Ningbo, Weihai 304 | Kun Wang Kun-hong Metal: Ganzhou 饶宜春 Wenzhou Changzhou 304 Nanchang | Kun Wang Kun-hong Metal: Changzhou, Jiangsu Huaian, Nanjing, Nantong sunshine 304 | Kun Wang Kun-hong Metal: Suzhou, Taicang, Changshu, Wujiang Luoyang Yantai 304 | Kun Wang Kun-hong Metal: Jiangyin Yixing, Wuxi, Xuzhou, Yancheng Jiaxing 304 | Kun Wang Kun-hong Metal: Huai'an Taicang, Yangzhou, Zhenjiang, Danyang Jingjiang 304 | Kun Wang Kun-hong metal: Jiang Yin Wujiang, Wuxi, Hangzhou, Huzhou Suqian 304 | Kun Wang Kun-hong Metal: Jinhua, Yiwu Nanchang, Qingdao, Zibo, Dongying 304 | Kun Wang Kun-hong Metal: Yuyao Yixing, Shanghai, Xi'an, Taizhou 304 | Kun Wang Kun-hong Metal: Yuyao, Shaoxing, Taizhou Huangyan Changshu Lishui 304 | Kun Wang Kun-hong Metal: Hefei, Nanjing, Xiamen, Wenzhou Yueqing Ryan 304 | Kun Wang Kun-hong Metal: Yantai, Zibo, Weifang, Weihai, Qingdao Jiaxing 304 | Kun Wang Kun-hong Metal: Kunshan, Zhangjiagang, Lianyungang Ma'anshan Weifang 304 | Kun Wang Jiang Su Kunhong Metal Materials Co., Ltd.
