General purpose stainless steel parts performance use summary

Many variable factors indicate the characteristics of the corrosive medium, ie, the chemical and its concentration, atmospheric state, temperature, and time, so if the correct properties of the medium are not known, it is difficult to use materials and select materials. However, the following can be used as a guide.

Type 304

Widely used materials. It can withstand general rust in buildings, resists corrosion from food processing media (but can corrode at high temperatures containing concentrated acids and chlorides), and is resistant to organic compounds, dyes and a wide variety of inorganic compounds.

Type 304L

(low carbon) good nitric acid resistance, and durable medium temperature and concentration of sulfuric acid, widely used as liquid gas storage tanks, as low temperature equipment (304N), other consumer products, kitchen equipment, hospital equipment parts, transportation vehicles, wastewater Processing device.

316L type

It contains slightly more nickel than Type 304 and contains 2% to 3% of molybdenum. Corrosion resistance is better than Type 304, especially in chloride media that tend to cause pitting corrosion. Model 316 has been developed for use as a sulphite pulper because it is durable with sulfuric acid compounds. Moreover, its use has expanded to handle many chemicals in the processing industry. most our LED LIGHT METAL PARTS are use this material.
