Characteristics and applications of commonly used stainless steels

Wuxi Puxin Machinery Factory | Updated: Jul 25, 2017

Now, let's talk about the characteristics and uses of the commonly used stainless steel categories.
304: as a widely used steel, corrosion resistance, good heat resistance, low temperature and mechanical strength, punching, bending and other thermal processing, no heat treatment hardening, non magnetic, temperature of minus 193 degrees to 800 degrees. Use: tableware, kitchenware, water heaters, boilers, auto parts, medical equipment, food machinery, wine storage, pressure vessel (chemical machinery, chemical equipment).
As of 304L low carbon steel 304, under general conditions, corrosion resistance and almost 304, but after welding and after stress relieving it anti intergranular corrosion, without heat treatment conditions, can maintain good corrosion resistance, general use, at 400 degrees, use: petrochemical the building materials industry.
321 in the 304 steel add the Ti element to prevent intergranular corrosion, for Yu Zheng 430 to 900 degrees Celsius, nonmagnetic; use: automobile exhaust, heat exchanger, container without heat treatment after welding products, due to the addition of Ti element, is not suitable for food processing equipment.
