Some metals are added to iron to create alloys that increase the desired properties of the user. Type 316 / 316L stainless steel, alloys are added to resist certain problems. There are different types of stainless steel 316 such as: L, F, N, H and some others. Each type is slightly different and each type is used for different purposes and is very popular in the market. In the following, Titanium materials will introduce two common stainless steels, widely used, as well as a basic comparison so that everyone knows the quality of these two stainless steels. It is 316 stainless steel and 316L stainless steel.
General quality of both 316 and 316L stainless
Inox 316 and stainless steel 316L have better corrosion resistance at higher temperature than stainless steel in grade 304
They also cannot harden by heating, and have good deep forming and stamping ability.
– Want to shape 316 / 316L stainless steel well, you need to incubate at 1038 – 1149 degrees C then shape is to cool quickly.
So what is the difference between Inox 316 and Inox 316L?
316 stainless steel contains more Carbon than 316L stainless steel, remember, the letter L stands for Low meaning low (low here is Low Carbon), although less carbon, Inox 316L is equivalent to most other functions. compared with 316 stainless steel. The same cost, good durability and good resistance to corrosion.
316L stainless steel is suitable for projects or products with multiple welds or stamping shapes because Inox 316, when welded or shaped, the decomposition in the chemical composition will be higher than even annealed before treatment. . 316L stainless steel is excellent for anti-corrosion products at high temperatures, so it is quite popular in construction and especially offshore and marine projects.
Inox 316 and 316L stainless is not an option if you need cheap goods, if you need cheap, you can choose 304 stainless steel or 304L stainless steel, it is not a choice for the most durable, if you need a more durable type. Choose Type 317 or Stainless Steel 317L (because the higher molipdel content helps them to better resist overall corrosion)
How is the quality of 316 stainless steel?
Inox 316 belongs to the austenite – Nickel stainless steel line containing 2-3% molipdel
Molybdenum content increases corrosion resistance, improves tolerance to chloride ion solutions and enhances high temperature.
Type 316 is especially good for acidic environments, this steel is effective in protecting against corrosion caused by sulfuric, hydrochloric, acetic, formic and tartaric acids, as well as sulfate acids and alkali chloride.
How is the quality of 316L stainless steel?
Type stainless steel, Inox 316L is a lower carbon version than 316 alloy. The lower carbon content at 316L minimizes harmful carbide precipitation during welding. Hence, 316L used when welding is required to ensure maximum corrosion resistance.
