316/316L Stainless Steel CoilIntroduction：316l steel is widely used in the chemical industry because of its excellent corrosion resistance. 316l steel is also a derivative of 18-8 austenitic stainless steel, with 2 ~ 3% Mo element added. On the basis of 316L, many kinds of steel are derived. For example, 316Ti is derived by adding a small amount of Ti, 316N is derived by adding a small amount of N, and 317L is derived by increasing Ni and Mo contents.Most of the 316l steel on the market is produced according to American standard. For the sake of cost, steel mills generally put the Ni content of products as low as possible. The us standard stipulates that the Ni content of 316l steel is 10-14%, while the Japanese standard stipulates that the Ni content of 316l steel is 12-15%. According to the minimum standard, there is a 2% difference between American standard and Japanese standard in Ni content, which is quite huge in price. Therefore, customers still need to see clearly when purchasing 316l steel products, and the products should refer to ASTM or JIS standard.With the Mo content of 316l, the steel has excellent pitting resistance and can be safely applied in environments containing Cl- and other halogen ions. Since 316L is mainly used for its chemical properties, steel mills have lower requirements for surface inspection of 316L steel (compared with 304), and customers with higher requirements should strengthen the surface inspection.

Which is better ss304 or ss316?

Since Type 316 stainless steel alloy contains molybdenum bearing it has a greater resistance to chemical attack than 304. Type 316 is durable, easy-to-fabricate, clean, weld and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature.
What is good quality stainless steel?
304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.

What is the difference between 304, 304H and 304L?

In fact, the content of chromium and nickel is 304 stainless steel, and the composition contains 18% chromium (Cr) and 8% nickel (Ni), but the main difference lies in the carbon content.

304L is an ultra-low carbon stainless steel. The carbon content is reduced to less than 0.03%, which can avoid intergranular corrosion. In theory, the effect of stress corrosion resistance is stronger than that of 304, but the effect is not obvious in practical applications. The purpose of reducing carbon and adding titanium is the same, but the smelting cost of titanium-added 321 is higher, the molten steel is thick, and the price is more expensive.

The H in 304H refers to high temperature. High carbon content is the guarantee of high temperature strength. GB150 requires that when austenitic steel is used above 525 degrees, the carbon content should not be less than 0.04%. Carbide is the strengthening phase, especially the high temperature strength. Better than pure austenite.

Among the three, the highest carbon content is 304H, the lowest carbon content is 304L, and the carbon content of 304 stainless steel is between the two. The higher the carbon content, the worse the corrosion resistance of stainless steel and the easier it is to rust. The difference in carbon content also causes the price to be different, or the requirements for different uses are also different.

Why is stainless steel so expensive?

Stainless steel is more expensive to produce because of the addition of the variety of alloying elements, such as iron, chromium, nickel, manganese and copper. … The chromium attaches itself to oxygen more readily than iron and thus creates a chromium oxide layer which protects the metal from degradation.
What is the safest stainless steel?
Stainless steel cookware is generally recognized as a safe material for cookware. Any good quality stainless steel, be it 304 or 316 stainless steel, is a better choice than most of the other available materials. For example, coated aluminum pans lose their non-stick over time.
