254SMO is a highly corrosion-resistant austenitic stainless steel, mainly used in environments of high-concentration chloride ion and highly corrosive media, such as seawater, salt water, wet chlorine, acetic acid, formic acid, acetic acid, hydrochloric acid, hypochlorous acid, sulfuric acid, nitric acid, etc.. On the other hand, it also possesses good processing performance and welding performance. Besides, it is very resistant to pitting and crevice corrosion as a result of its high content of chromium and molybdenum. As this special stainless steel is a high-alloy material, the manufacturing process is quite complex. Generally, only traditional processes are adopted to manufacture this special stainless steel, such as pouring, forging, rolling, etc.

S32750/2507 /1.4410is an ultra-duplex stainless steel including 25% chromium, 4% molybdenum and 7% nickel. In terms of chemical composition, the chromium and molybdenum content of 2507 stainless steel is relatively high, which leads to its superior corrosion resistance to various acids. The duplex construction of 2507 stainless steel gives it excellent resistance to stress corrosion cracking. Cracks are an inevitable problem in construction and other related fields, and 2507 stainless steel can perform excellent corrosion resistance in an environment containing chloride ions, making it an excellent option for construction and related industries. 2507 stainless steel also has excellent mechanical properties with high compressive strength, impact strength and low coefficient of thermal expansion, which is why it is often put into use in oil and gas industry, and fields such as water treatment, fire protection, desalination equipment, mechanical parts and fuel gas purification equipment.

S32205/1.4571 Duplex stainless steel pipe has more than twice of yield strength than ordinary austenitic stainless steel, and it has enough plastic toughness required for molding. 2205 duplex stainless steel has excellent corrosion resistance. Because it contains 22% chromium and 3% molybdenum, it can show better corrosion resistance than 316L and 317L in most environments. This alloy also performs well when it comes to localized corrosion resistance. In oxidizing and acidic solutions, 2205 Duplex stainless steel pipe is highly resistant to pitting and crevice corrosion. Moreover, when compared with austenitic stainless steel with similar alloy content, its wear corrosion resistance and fatigue corrosion performance are better than austenitic stainless steel. Whether under dynamic load or static load conditions, 2205 duplex stainless steel has a higher energy absorption capacity than austenitic stainless steel, which has obvious advantages for structural parts to cope with emergencies such as collisions, explosions, etc..

SUS304L/1.4307stainless steel pipe is a variant of 304 stainless steel pipe with a lower carbon content and is often used in welding scenarios. The lower carbon content greatly reduces the precipitation of carbides in the heat-affected zone close to the weld, and the precipitation of carbides is associated with intergranular corrosion of stainless steel in certain environments. Basically, the need to anneal weld joints prior to using the completed metal form is not needed using 304L, saving time and effort. Generally speaking, both 304 and 304L stainless steel plates can be used for many of the same applications. The differences are often not significant enough that one is considered more useful over the other. 304L stainless steel plate is more commonly used in fields such as food processing equipment, building materials, automobile parts.

SUS304 /1.4307 stainless steel pipe is the most common type of steel pipe across the globe for a number of its characteristics. 304 stainless steel is primarily composed of iron, chromium and nickel.
