Popular Grades
•304 Stainless Steel Channel: It is a very common grade. It has excellent corrosion resistance in nitric acid with a concentration of ≤65% at boiling temperature and has good corrosion resistance to alkali solutions and most organic and inorganic acids. It is widely used in construction, steel frame structures, vehicle manufacturing and other industrial structures.
•316 Stainless Steel Channel: It has better corrosion resistance than 304, especially in chloride ion-containing environments such as seawater and chemical industry. It is often used in some high-corrosion environment applications such as marine engineering, chemical equipment and food processing equipment.
Popular Q&A
Q: What are the advantages of 304 stainless steel channel?
A: 304 stainless steel channel has strong corrosion resistance in nitric acid with a concentration of ≤65% at boiling temperature and has good corrosion resistance to alkali solutions and most organic and inorganic acids. It also has good high temperature resistance, and its mechanical properties and workability are relatively good.
Q: What is the difference between 304 and 316 stainless steel channels?
A: The main difference is the corrosion resistance. 316 stainless steel channel has better corrosion resistance than 304, especially in chloride ion-containing environments. In addition, the price of 316 stainless steel is generally higher than that of 304.
Q: How to measure the size of stainless steel channel?
A: It is usually measured by width (a) × flange (b) × web (c) × length. The width refers to the overall width of the channel, the flange is the width of the protruding part on both sides, the web is the vertical part in the middle, and the length is the length of the channel.
