Stainless steel plates and stainless steel coils
Stainless steel, an alloy composed of iron, chromium, carbon and other elements, is also known as “white iron” in Taiwan, because its surface looks white and is anti-rust. Stainless steel is extensively applied used and can be seen everywhere in life, such as stainless steel cleaning boxes, carts, sinks and product racks, etc.. As stainless steel products are 100% recyclable and reused, they still retain residual value even if they come to the the end of their life.

Application of stainless steel plates and stainless steel coils to products
- 200 series: Ranking the industrial grade, with poor corrosion resistance and at low price, it is extensively applied as a cheap alternate for 300 series domestically and applicable to iron windows and doors, etc..
- 300 series: Food grade, such as 304 stainless steel, applicable to tableware, corrosion-resistant containers and medical equipment, etc..
- 301: Good ductility and applicable to molded products. It can also be hardened rapidly through mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
- 302: The corrosion resistance is as same as 304, but the strength is better because of the higher carbon contents.
- 303: By adding a small amount of sulfur and phosphorus, it is easier to cut 303 than 304.
- 304: Universal model; i.e. 18/8 stainless steel. Products, such as corrosion-resistant containers, tableware, furniture, railings and medical equipment. The standard ingredients are 18% Chromium plus 8% Nickel. It is a non-magnetic stainless steel, and it is impossible to change its metallographic structure through heat treatment.
- 304 L: With the same characteristics as 304, but low carbon makes it more corrosion-resistant and easy for heat treatment. Notwithstanding, due to the poor mechanical properties, it is more suitable for welding, and products that cannot be processed by heat treatment easily.
- 304 N: It has the same characteristics as 304. It is a nitrogen-containing stainless steel. Nitrogen is added in order to improve the strength of the steel.
- 309: With better temperature resistance than 304, and temperature resistance up to 980℃.
- 309 S: The massive chromium and nickel contained therein result in better heat resistance and oxidation resistance, including the products, such as heat exchangers, boiler components, and jet engines.
- 310: With excellent high temperature and oxidation resistance, up to the temperature 1200℃.
- 316: It is the second most extensively applied steel type after 304. It contains molybdenum and, therefore, is better at corrosion resistance, applicable to surgical equipment and high-price pots, etc. and primarily applied to the food industry, watches and clocks, jewelry, pharmaceutical industry and surgical equipment. Molybdenum is added in order to make it become a special structure that resists corrosion. Because it is better at resistance to chloride corrosion than 304, it is also used as the “ship plate.” SS316 is usually applied to nuclear fuel recovery devices.
- 316 L: The low carbon makes it more corrosion-resistant and processed easily by heat treatment, including the products, such as chemical processing equipment, nuclear power generators and refrigerant storage tanks.
- 321: With the properties similar to 304, except the addition of titanium resulting in mitigation of the risk over weld corrosion.
- 347: Added with stabilizing element niobium, suitable for welding aviation equipment parts and chemical equipment.
- 400 series: Food grade, such as 430 stainless steel, which may be processed easily, better at nitric acid corrosion resistance, and also magnetic.
