Stainless Steel Grade AISI 410 | EN 1.4006 | DIN X12CrN13

AISI 410 | EN 1.4006 | DIN X12CrN13 - is a general-purpose martensitic stainless steel. It contains 11.5% chromium, which provides good corrosion resistance. However, the corrosion resistance of steels can be further improved by a number of processes, such as hardening, tempering and polishing. Hardening and tempering make it possible to strengthen the steel. Typically, such stainless steels are used in areas involving moderate corrosion, heat resistance and high strength.

EN 1.4006 is sufficiently resistant to the effects of hot gases, steam, foodstuffs, weak acids and alkalis, fresh water and dry air.

This steel achieves maximum corrosion resistance and heat resistance through hardening. However, it is less resistant to corrosion than austenitic grades and ferritic alloys of the AISI 430 grade, which contain 17% chromium. The smooth polished surface provides improved steel characteristics.

Physical properties

Steel AISI 410 | EN 1.4006 | DIN X12CrN13 magnetic.

Heat resistance

Stainless steel grade AISI 410 has good resistance to scale formation at temperatures up to 650 °C. However, the mechanical properties of the material will decrease in the temperature range from 400 to 580 °C.

Technological properties

⓵ Welding

Steel can be welded using all normal welding methods, but materials should be preheated to temperatures between 150 and 260 °C followed by post weld annealing treatment to reduce cracking.

⓶ Mechanical processing

Steel is easily machined under conditions of strong tempering or annealing. However, it is very difficult to machine steel hardened above 30 HRC.

⓷ Heat treatment

This stainless steel can be fully annealed at temperatures from 815 to 900 °C, followed by slow cooling in a furnace and air cooling. Technological annealing of steel can be carried out at temperatures from 650 to 760 °C and with air cooling.

⓸ Forging

Care should be taken when forging stainless steel grade AISI 410 | EN 1.4006: gradual heating to a temperature of about 800 °C before more rapid heating to a temperature of 1150 °C to 1180 °C is recommended. Forging then takes place between 1180 °C - 950 °C and then slow cooling in a furnace or in dry ash or similar material to facilitate slow cooling.
