Introduction:
316L stainless steel pipe is a hollow long round steel material, which is mainly widely used in industrial transportation pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instrumentation and so on.
316L is widely used in the chemical industry because of its excellent corrosion resistance. 316L is also a derivative steel type of 18-8 austenitic stainless steel with 2 to 3% Mo element added. On the basis of 316L, many steel grades are derived, for example, 316Ti is derived after adding a small amount of Ti, 316N is derived after adding a small amount of N, and 317L is derived by increasing the content of Ni and Mo.
316 stainless steel: corrosion resistance is better than 304 stainless steel, and has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere.
Features:
316L steel that is resistant to weak corrosive media such as air, steam, water, and chemically aggressive media such as acids, alkalis, and salts. Also known as stainless steel acid-resistant steel. In practical applications, steel that is resistant to weak corrosion media is often called stainless steel, and steel that is resistant to chemical media corrosion is called acid-resistant steel. Due to the difference in chemical composition of the two, the former is not necessarily resistant to chemical media corrosion, while the latter are generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element that enables stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about 1.2%, chromium reacts with the oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface. Can prevent the basic further corrosion of steel. In addition to chromium, commonly used alloy elements include nickel, molybdenum, titanium, niobium, copper nitrogen, etc., to meet the requirements of stainless steel structure and performance for various uses.
Classification:
1. Ferritic stainless steel with chromium content of 12%-30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is superior to other types of stainless steel.
2. Austenitic stainless steel, containing more than 18% chromium, and about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and is resistant to various media.

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.
