DIN EN 1.4307 Stainless Steel Tube used in storage tanks, pipes, reactors and pumps
The corresponding domestic grade of 1.4307 is 06Cr19Ni10, also known as 304 stainless steel (S30403). In the American Standard (ASTM), 1.4307 corresponds to the grade 304L. It is an ultra-low carbon austenitic stainless steel developed to solve the serious intergranular corrosion tendency of the material caused by the precipitation of Cr23 and C6 of 304 material under some conditions. Its sensitized resistance to intergranular corrosion is significantly better than that of 304, except for slightly lower strength, other properties are the same as 304. It can be welded with a variety of universal stainless steel welding processes, and it can be welded without heat treatment. This stainless steel is widely used in the equipment manufacturing of food processing, chemical, petroleum and other industries.
Applications:
1.4307 Stainless steel has a very good compatibility with many chemical substances, so it is mainly used in the chemical industry, electronic industry and medical equipment.
In the chemical industry, it can be used as a manufacturing material for equipment such as storage tanks, pipes, reactors and pumps.
In the electronics industry, it is often used to manufacture semiconductor devices and other highly sophisticated electronic devices.
In terms of medical equipment, it can be used to manufacture medical equipment such as surgical tools, dental equipment and orthopedic stents.
