409 stainless steel is a ferritic steel with good mechanical properties and high temperature corrosion resistance. It contains 11% chromium, which is the minimum amount required to form the passive surface film that makes stainless steel corrosion-resistant.

201 stainless steel generally refers to 201 stainless steel and acid resistant steel. 201 stainless steel refers to the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.

2507 duplex stainless steel is a special ferritic-austenitic duplex stainless steel with excellent corrosion resistance. It achieves comprehensive protection against point corrosion, crevice corrosion and uniform corrosion through the ratio of chromium and molybdenum elements.

316 stainless steel also contains 2-3% molybdenum, in addition to iron, chromium and nickel. The addition of molybdenum significantly improves the performance of 316 stainless steel in certain corrosive environments, especially those containing chlorides. 316 stainless steel is more commonly used in situations requiring higher corrosion resistance.

316L stainless steel has a lower proportion of carbon in its composition. To qualify as 316L stainless steel, the amount of carbon cannot exceed 0.03%. This decreases the risk of carbon precipitation, making it a better option for welding to ensure maximum corrosion resistance.

2205 Duplex stainless steel alloy is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness and good overall and local resistance to stress corrosion.

440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, the highest strength, hardness and wear resistance of all the stainless alloys after heat treatment

316Ti is a titanium stabilized version of 316 molybdenum-containing austenitic stainless steel. It is more resistant to general corrosion and pitting/crevice corrosion than traditional chromium-nickel austenitic stainless steels such as 304.

304 stainless steel highly stands out in terms of corrosion resistance, heat resistance, low temperature strength and mechanical properties, being one of the most widely used types of stainless steel. In addition, it has exceptional hot-workability such as stamping and bending, without leaving heat treatment hardening phenomenon.
