How to distinguish between 304 stainless steel pipe and 316 stainless steel pipe?

[导读] : We all know that 316 stainless steel pipe is more expensive than 304 stainless steel pipe, for the two performance differences or many customers consulting, consulting more is the difference between the use of stainless steel pipe 304 and 316.

We all know that 316 stainless steel pipe is more expensive than 304 stainless steel pipe, for the two performance differences or many customers consulting, consulting more is the difference between the use of stainless steel pipe 304 and 316.

304 stainless steel tube and 316 are stainless steel code, essentially they have no difference are stainless steel, but broken down they belong to different kinds. 316 stainless steel tube quality is greater than 304 stainless steel tube, 316 stainless steel tube in 304 based on the integration of the metal molybdenum, this element can be more consolidation of stainless steel's molecular structure, so that it is more wear-resistant oxidation, and at the same time the corrosion resistance is also greatly increased. At the same time, the corrosion resistance is also greatly increased. So the difference between the two applications in which?

304 stainless steel tube application range

304 stainless steel tube is a widely used chromium - nickel stainless steel tube, as a kind of wide range of steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending and other hot workability is good, no heat treatment hardening phenomenon in the atmosphere corrosion resistance, if it is an industrial atmosphere or heavily polluted areas, you need to clean in time to avoid corrosion. Suitable for use in the field of decoration, (stainless steel security windows, stainless steel staircase handrails, etc.), automotive parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemical, food industry, agriculture, ship parts and so on. The use of 304 stainless steel tubes in dry indoor environments works quite well. However, to maintain its appearance outdoors in villages and cities, it needs to be cleaned frequently. However, 316 stainless steel tubes are used in highly aggressive industrial or marine atmospheres.

316 Stainless Steel Pipe Applications

316 Stainless Steel Pipe is a steel that is superior to 304 material in all aspects such as corrosion resistance. It is mainly used in petroleum, chemical, medical, food, machinery, instrumentation, CNC processing and other industrial piping, coastal facilities, seawater production equipment due to the use of environmental salt content is high, also need to use 316L material. In addition, it is widely used in chemical, construction, bridge, aerospace, mechanical hardware, medical, decoration, medical fitness products, furniture, tableware manufacturing, liquid transportation, automobile manufacturing, water supply, solar energy, machinery manufacturing, nuclear power, building decoration, rail transportation, sanitary ware, metal products, container and other industries.

When we purchase stainless steel decorative pipe, stainless steel decorative pipe used in the environment, determines the service life, corrosion media composition, temperature, pressure is an important factor to consider when choosing the right stainless steel decorative pipe steel. So when choosing stainless steel tube, it is necessary to choose according to the use of the situation.
