What is SUS304 and SUS430?
- Stainless SUS 304
Grade 304 is the standard 18/8 stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. SUS 304 is also excellent in a wide range of atmospheric environments and many corrosive media.
Typical applications include:
-Food processing equipment, particularly in beer brewing, milk processing & wine making.
-Kitchen benches, sinks, troughs, equipment and appliances
-Chemical containers, including for transport
-Automotive parts such as spring, heat exchanger
- Stainless SUS 430
Grade 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application. 430 has good resistance to a wide variety of corrosive media including nitric acid and some organic acids. Compared to SUS304, a lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable.
- What is 18/10 ?
Stainless steel is available in two qualities: 18/0 or 18/10 (there is also 18/8 but this is similar in properties to 18/10) The 18 refers to 18% chromium which is added to the steel mix to give it stainless properties. The 10 refers to nickel which adds to those properties and also gives a silvery sheen. 18/0 is much less expensive than 18/10 and most cutlery sold today is made from this material.
18/10 gives greater protection against corrosion and has a softer shine: most contemporary patterns are made from this top grade stainless steel. 18/0 and 18/10 are both fully dishwasher-safe 18/10 and 18/8 will not stick to magnet, 18/0 will stick to a magnet.
