General features

Alloy 410 (UNS S41000) is a martensitic stainless steel containing 12% chromium that can be heat treated with a wide range of mechanical properties。The alloy has good corrosion resistance, high strength and high hardness。410 is easy to stretch and form after annealing。It remains magnetic after annealing or heat treatment。

The corrosion resistance

Alloy 410 has corrosion resistance in atmosphere, water and some chemicals。It can be used in environments containing mild or dilute acetic acid, naphthalene acetic acid, nitric acid and sulfuric acid。The alloy is also corrosion resistant to acids in food。

The 410 can also be used in mildly chlorinated or contaminated water。It also works well in oil and gas applications that are contaminated or where hydrogen sulfide is present in small amounts。However, the alloy is susceptible to chloride corrosion (especially in oxidation conditions)。

The 410 works well in environments where moderate corrosion resistance and high mechanical properties are required。

The oxidation resistance

Alloy 410 maintains oxidation resistance at temperatures up to 1292°F (700°C) and intermittently at temperatures up to 1500°F (816°C)。

Manufacturing data

 

Heat treatment

Annealing -- Air cooling in furnace to 1100°F (593°C) when temperature slowly rises to 1500-1650°F (816-899°C)。
Annealing in process - air cooling at 1350-1450°F (732-788°C)。
Quenching - Air cooling or oil quenching at temperatures of 1700-1850°F (927-1010°C)。Stress relief annealing or tempering should follow。
Stress relief annealing - air cooling at 300-800°F (149 -- 427°C) for one to two hours。
Tempering - Heat to 1100-1400°F (593-760°C) and leave for one to four hours for air cooling。

Cold forming

The alloy can be cold worked and moderately formed under annealing condition。

Hot forming

It is usually carried out in the temperature range of 1382-2102°F (750-1150°C), followed by air cooling。For plate deformations such as bending, preheating should be carried out in the temperature range of 212-572°F (100-300°C)。If the plate is substantially deformed, it should be reannealed or stress-relieved annealed at approximately 1202°F (650°C)。

加工

Alloy 410 is best annealed at 60 to 80 feet per minute (18.3-24.4 meters) for processing。Post-processing purification and passivation are recommended。

焊接

Due to its martensitic structure, 410 alloy has limited weldability due to its hardenability。Post-weld heat treatment should be considered to ensure that the desired properties are met。AWS E/ER 410, 410 NiMo, and 309L are the alloys most often specified when welding fill is required。
