What is SUS304？
X5CrNi18-10 for SUS304 model, SUS304 is a kind of stainless steel, is austenitic stainless steel. Also becoming 18/8 stainless steel, SUS304 has a higher nickel content and lower carbon content than other stainless steel alloys. With its high corrosion resistance and durability, SUS304 stainless steel is ideal for food storage and preparation, water filtration and medical equipment.
SUS304 application
SUS304 is the most common stainless steel grade and is used in many applications. SUS304 is an austenitic grade with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It has good forming and welding characteristics and is often used in food processing and storage equipment, kitchen benches, sinks, heat exchangers, pipelines, and architectural applications such as handrails and outdoor fixtures. It is also used in chemical containers, including for transport.

FAQ
What is SUS304 grade?
SUS304 is a type of stainless steel used in a wide range of applications. SUS304 is a chromium-nickel alloy that is part of the 300 series of stainless steel alloys. SUS304 has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. SUS304 is known for its excellent corrosion resistance, heat resistance, strength, and workability. SUS304 is often used in food processing equipment, kitchen sinks, and other applications that require an attractive finish and corrosion resistance.
Will SUS304 stainless steel rust?
No, SUS304 stainless steel is highly resistant to rust and corrosion due to its composition, which includes chromium and nickel. However, it can still corrode under certain conditions, such as in high-saline or acidic environments.
Is 304 stainless OK for drinking water?
Yes, 304 stainless steel is safe for drinking water. It is one of the most commonly used stainless steels, and is not known to leach any chemicals into the water.
