304 stainless steel is one of the most popular and widely used stainless steel grades due to its excellent corrosion resistance, high strength, and formability.Grade 304 is a type of austenitic stainless steel that contains 18% chromium and 8% nickel,which also referred to as 18/8 stainless steel.304 steel has good corrosion resistance and temperature resistance, is not easy to rust at room temperature, and has good processing properties and welding properties.
304 stainless plate also has good intergranular corrosion resistance. For oxidizing acids, it still has strong corrosion resistance in nitric acid below the boiling temperature of ≤65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.It is widely used in industrial, home improvement, food and medical fields, and can resist most of the corrosion of organic and inorganic acids and alkali solutions.
In addition,Grade 304 is not easy to rust at room temperature, and has good processing properties and welding properties.It is also non-magnetic and has good mechanical properties, making it a durable and long-lasting material choice.
