410 Stainless Steel is considered a hardenable martensitic steel alloy, which is unlike other austenitic grades, which cannot be heat treated in order to generate a high strength, as well as, a good ductility. 410 Stainless Steel alloy is required when hardness, wear resistance, and strength is required, as well as, some resistance to corrosion.
Due to the 410 Stainless Steel capabilities of hardening, the resulting performances are somewhat compromised as well as other properties. 410 Stainless Steel Alloy can only be effectively used in environments that are considered mildly corrosive. Its operating temperature range is limited due to two factors; its loss of its strength by over tempering at temperatures that are elevated and at sub-zero temperatures its loss of ductility.
This type 410 Stainless Steel is officially considered a stainless steel but by its characteristics the material is in all actuality, a compromise of a high carbon steel alloy and a chromium stainless steel. 410 Stainless Steel is considered ideal for the use in the manufacturing of parts that are under high stress, these parts may be found within a variety of industries such as automotive and power generation.
Resisting Corrosion
410 Stainless Steel is exceptional in a broad range of atmospheric environments as well as many corrosive media types. It is subject to crevice and pitting corrosion in such environments as a warm chloride environment, as well as to stress corrosion cracking at temperatures that are above about 60°C. 410 Stainless Steel also resists dry atmospheres conditions, mild alkalies, acids, fresh water, food, hot gases, and steam.
Heat Resistance
410 Stainless Steel has a good quality oxidation resistance in irregular service to 870°C and in constant service to 925°C. Uninterrupted use of 304 in the 425-860°C range is not suggested if successive aqueous corrosion resistance is imperative. Grade 304L is more opposed to carbide precipitation and may be heated into the above temperature array.
Background
410 Stainless Steel is the central martensitic stainless steel; like the majority of non-stainless steels it is capable of be hardened by a “quench-and-temper” high temperature treatment. 410 Stainless Steel contains a smallest amount of 11.5 per cent chromium, just enough to give deterioration resistance properties. It achieves the greatest corrosion resistance when it has been tempered, hardened, as well as polished.
Applications
Typical uses of 410 Stainless Steel include:
- Mine ladder rungs
- Bolts
- Petroleum fractionating towers
- Nuts
- Steam and gas turbine parts
- Screws
- Pump and valve parts and shafts
- Bushings
