2205 duplex stainless steel

Chemical composition: 22% chromium, 5% nickel, 3% molybdenum, and 0.18% nitrogen. Mechanical properties: Tensile Strength:620MPa,Yield Strength: 450MPa, Elongation:25%.

Corrosion resistance: It has excellent corrosion resistance and is suitable for various corrosive media, including acid, alkali, salt, etc. The resistance to chloride stress corrosion is superior to general austenitic stainless steel.

Characteristic: 

Oxidation resistance: 310S stainless steel has good oxidation resistance and can maintain stability in high temperature environments.

Corrosion resistance: Due to its high chromium and nickel content, 310S stainless steel has good corrosion resistance and is suitable for a variety of corrosive environments.

High hardness martensitic stainless steel industrial welding pipe is mainly used for high strength and hardness applications, and requires a certain corrosion resistance. Martensitic stainless steel is named for its high hardness and strength after heat treatment, and is suitable for the manufacture of cutting tools, springs, bearings, valves, pump bodies and other parts.

904L stainless steel is a super austenitic stainless steel with very high corrosion resistance, especially in environments containing chlorides.It is a high-alloy stainless steel with high chromium, nickel and molybdenum content, as well as a small amount of copper and nitrogen.

C276/S32760 (Hastelloy C-276)

Chemical composition: C276 alloy contains a high proportion of nickel (about 59%), as well as molybdenum, chromium, tungsten and other elements. Its chemical formula is usually expressed as 00Cr15Ni60Mo16W4.

Hastelloy GH3044

Chemical composition: GH3044 is a nickel-chromium-based solid solution reinforced superalloy, which contains high chromium and tungsten content, as well as a small amount of molybdenum, iron, aluminum and other elements.

Chemical composition: Incoloy 800 is a nickel-iron-chromium alloy that contains a high proportion of nickel (about 30-35%), chromium (about 19-23%) and iron (about 39-45%).It also contains small amounts of carbon, manganese, silicon and copper.

Chemical composition: NO6600 is a nickel-chromium-iron-based solid solution reinforced alloy that contains nickel, chromium, iron and other elements. Specific components may include nickel (about margin), chromium (about 19-23%), iron (about 5-10%), and a small amount of carbon, manganese, silicon, etc.

TP316L Stainless steel welded pipe is a kind of austenitic stainless steel material, it belongs to the 316 series, in which the "L" represents the low carbon (Low Carbon). This material is particularly suitable for use in situations where welding is required because of its excellent welding properties and corrosion resistance. TP316L Stainless steel welded pipe is widely used in chemical industry, petroleum, food processing, pharmaceutical, paper making, Marine engineering and other industries.

TP316Ti Stainless steel welded pipe is an austenitic stainless steel material, it belongs to the 316 series, contains titanium as a stabilizing element. This material is particularly suitable for use in high-temperature and corrosive environments, such as in the chemical, petroleum, food processing, pharmaceutical, and other industries. TP316Ti The titanium stabilization of stainless steel welded pipe helps to prevent intercrystalline corrosion, which is due to the strong affinity of titanium and carbon, and the preferential combination with carbon to form stable titanium carbide, so as to prevent the formation of chromium carbide at the grain boundary and protect the corrosion resistance of the material.

15X25T is a steel grade, "15" represents a carbon content of approximately 0.15%, "X" represents the content of alloying elements, and "25 T" indicates that the steel contains 25% of alloying elements. In the Russian standard, this type of steel belongs to the category of alloy structural steel and is typically used to manufacture mechanical parts that withstand high loads and impacts.

Anti-intercrystalline corrosion: Due to the addition of titanium, TP 321 stainless steel welded pipe can resist intercrystalline corrosion, which is due to the strong affinity of titanium and carbon, preferentially combined with carbon to form a stable titanium carbide, thus preventing the formation of chromium carbide at the crystal boundary, and protecting the corrosion resistance of the material.
