Product Description

Introduce

304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm3, also known as 18/8 stainless steel in the industry. As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties; The stamping, bending and other hot working properties are good, and there is no heat treatment hardening phenomenon (use temperature - 196 ºC~800 ºC). Corrosion resistance in the atmosphere. If it is an industrial atmosphere or heavily polluted area, timely cleaning is necessary to avoid corrosion. Suitable for food processing, storage, and transportation. It has good processing performance and weldability. Plate heat exchangers, corrugated pipes, household items (Category 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), automotive accessories (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship components, Xiaomi mobile phones, etc. 304 stainless steel is a nationally recognized food grade stainless steel.

Most usage requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted. However, other applications are increasingly seeking structural integrity or impermeability. For example, the roofs and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than aesthetics, even if the surface is not very clean. The use of 304 stainless steel in a dry indoor environment is quite effective. However, in rural and urban areas, frequent cleaning is necessary to maintain its appearance outdoors. In heavily polluted industrial areas and coastal areas, the surface can be very dirty and even produce rust.
But to achieve aesthetic effects in outdoor environments, nickel containing stainless steel needs to be used. Therefore, 304 stainless steel is widely used for curtain walls, side walls, roofs, and other building purposes, but in highly corrosive industrial or marine atmospheres, it is best to use 316 stainless steel. The advantages of using stainless steel in structural applications have been fully recognized for stainless steel sliding doors. Several design criteria include 304 and 316 stainless steel. Because the "dual phase" stainless steel 2205 combines good atmospheric corrosion resistance with high tensile strength and elastic limit strength, it is also included in European standards. In fact, stainless steel is produced in full standard metal shapes and sizes, and there are many special shapes available. The most commonly used products are made from thin plates and strips, and special products are also produced from medium thick plates, such as hot-rolled structural steel and extruded structural steel. And there are also circular, elliptical, square, rectangular, and hexagonal welded pipes or seamless steel pipes and other forms of products, including profiles, bars, wires, and castings.
