Temper rolled Spring Steel W.-Nr. 1.4310

 

 

 

 

1. Applications:

The alloy 1.4310 (AISI 301) has a good corrosion resistance due to a content of 17% Chromium and 7% Nickel. A high tensile strength is obtained by cold rolling. Compared to alloy 1.4301 (AISI 304) a much higher tensile strength of more than 2000 N/mm² can be reached. Because of this, the alloy 1.4310 is suitable for stainless feeler gage stock, precision foils, stainless springs and parts of higher strength. This alloy is little magnetic and can not be hold by magnetic tables of grinding machines. Available in more than 60 thicknesses between 0.003 and 3.0 mm and in different tensile strengths.

 

Further applications:

welded steel belts, transport belts

 

The alloy 1.4310 is suitable for spring according to DIN 17 224 (new: DIN EN 10 151).

 

At high demands for hardness and wear resistance we suggest the alloys 1.4031Mo (up to

0.80 mm thickness) and 1.4034 (1.0 to approx. 8.0 mm thickness).

7.  Further mechanical properties

Yield Str. Rp0,2 :         depending on tensile strength Elongation A 80:     depending on tensile strength

 

If good tumbling is done, the following values can be achieved: Reversed bending stress (Mean stress = 0):

550 MPa (50 % of the tested samples survive 2 million cycles at normal environment), if bending direction is at a 90° angle to the rolling direction

 

Fluctuating bending stress (Minimum stress = 0):

420 MPa (50 % of the tested samples survive 2 million cycles at normal environment), if bending direction is at a 90° angle to the rolling direction

 

As the fatigue strength depends on different factors like the corrosive conditions and the edge treatment, no definitive endurance limit values can be guaranteed.

At high forces or bending not in the right angle to the rolling direction hardened steels like the alloy 1.4031Mo are strictly recommended.

 

The operation temperature should not exceed 120-250°C (compare to DIN 17224 – stainless strip steel for springs). Please remember that the modus of elasticity decreases at higher temperatures.

 

8.  Physical properties:

Density:                                 7,9 g/cm³

Thermal conductivity:          15-19 W/(m °C) depending on the temperature Spec.heat capacity:       500 J/(kg °C) mean value at 50 – 100 °C Thermal expansion:   15,5 x 10 -6 (between30 - 100 °C)

16,0 x 10 -6 (between 30 - 200 °C)

16,5 x 10 -6 (between 30 - 300 °C) Electricresistance:       0,73 Ohm x mm²/m

 

Modus of elasticity:             185 000 MPa at 20 °C

 

Relative Permeability µr:    maximal 24 (further data: see chapter 13)

 

9.  Blanking

We recommend a punch-to-die clearance of 4-10 % of the strip thickness.

The corner radius should be at least 0.25 mm and the punching die should be at least twice the strip thickness.

The pieces should then be tumbled to receive a good edge roundness.

 

10.  Laser cutting

This alloy can be laser cut without problems.

 

11.  Photo etching

The alloy 1.4310 can be etched easily.

 

12.  Bending

As the high hardness of 1.4310 is obtained by temper rolling, the rolling direction has a big influence on the bending.

The suggested minimum bending radius also depends on the tensile strength. Bending at right angle (90°) to the rolling direction:

We suggest the tensile strength of 11-1300 N/mm² for bended pieces

 

13.  Flat grinding

In the temper rolled condition this alloy is only little magnetic and can not be holy by magnetic clamping devices of flat grinding machines.

 

The alloy 1.4310 has an austenitic structure in the annealed condition and is therefore nearly unmagnetic. The temper rolling leads to a change in the structure from austenitic to martensitic which causes an increase of magnetizability.

 

As this depends on several factors like the deformation degree, the material temperature during rolling and the chemical composition of the alloy, no specific data can be given.

 

At a deformation degree of 50%, the relative permeability should be not more than 10 to 18, and at a deformation degree of 70% the relative permeability should be not more than 15 to 24 (at 200H).

 

14.  Welding

The alloy 1.4310 can be welded easily. At the weldseam a change in the structure occurs due to the welding heat which decreases the strength.

Due to a content of approx. 0.10% of Carbon local corrosion at the weldseam is possible.

For critical applications the alloy 1.4404 (AISI 316L) with a verly low content of Carbon of less than 0.03% is recommended.

 

15.  Corrosion resistance

This alloy is in the group 4 in the Nirosta-table of corrosion resistance of stainless steels (see www.nirosta.de/Publikationen). This alloy is less resistant than the alloys 1.4404 (in group 5), but better resistant than the grades 1.4031Mo and 1.4034 (both in group 1).

 

Nirosta is a registered trade mark of ThyssenKrupp AG.

 

Please check there and by tests if the alloy 1.4310 is resistant enough for your application. As alternative, the alloy 1.4404 (AISI 316L) is available in the strength 11-1300 N/mm² in the thicknesses 0,01-0,02-0,05-0,10-0,15-0,20-0,25-0,30-0,40 and 0,50 mm.
