1.4310, DIN X12CrNi177, AISI 301

Designation by Standards

 

Chemical Composition (in weight %)

Description
301 is a commonly available austenitic stainless with good corrosion resistance and elevated carbon to allow for cold working to a variety of tempers.

Applications
Automotive trim, kitchen equipment, hose clamps, wheel covers, aircraft components and a wide variety of industrial applications. Springs up to temperature 300^oC, pulp cutting machine blades.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 200, 194 (100^oC), 186 (200^oC)
Density [g/cm³]: 7.9
Thermal conductivity [W/m.K]: 15.0
Electric resistivity [Ohm mm²/m]: 0.73
Specific heat capacity[J/g.K]: 0.50

Coefficient of Linear Thermal Expansion 10^{-6 o}C^-1

Hardening
Harden from a temperature of 1010-1120^oC followed by water quenching. For thin sections air cooling is acceptable, while heavier sections should be water quenched.

Forging
Hot forming temperature: Commence forging at 1093-1204^oC and finish at 927^oC.

Machinability
No data.

Corrosion Resistance
This alloy is resistant to the atmosphere, fresh water and mild environments. It will resist oxidation at temperatures up to 840^oC.

Welding
All popular techniques may be used, however the material will lose temper in the heat affected weld zone.

Cold working
Most common cold work methods are successful with this alloy. It should be understood however that the material will be more difficult to work than other austenitic stainless steels due its high work hardening rate.
