We could produce 317LN springs,317 LN springs,317 LN Compression Springs,317LN Extension Springs,317LN Torsion Springs,317 LN tension spring, 317LN disc spring, 317LN wave spring,317 LN Spiral Springs,317LN Automotive Springs,317LN Elevator Springs,317LN coil springs,317LN Conical Springs,317LN Tapered Springs,317LN Barrel Springs,317 LN die springs,317 LN Constant Force Springs,317 LN Power Springs,317 LN Garter Springs,317LN retaining Springs,317LN Volute Springs,317LN flat springs,317LN Volute Springs,317LN battery springs,317LN Spring Clips,317LN Battery Contacts from china
The diameter of 317LN springs that we could do range from 0.30 mm to 3.00 mm.
Our 317LN springs come in a variety of surface finishes from bluing to clear or yellow zinc electroplating, electrolytic nickel, powder coating and zinc phosphate coating always executed by specialized subcontractors
At the end of the manufacturing and stress relief cycles, clients require different and very specific types of treatments in order to improve 317LN spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.
317LN has higher yield and tensile strength than 317L. This low carbon grade steel provides resistance to sensitization during welding and thermal processes.
The chemical composition of 317 LN springs is as follows
C | Si | Ni | Mn max. | P max. |
≤0,03 | ≤1,00 | 12,5-14,5 | 2 | 0,045 |
Cr | Mo | N |
| S max. |
16,5-18,5 | 4,0-5,0 | 0,12-0,22 |
| 0,015 |
The mechanical property of 317LN spring is as follows
Properties | Imperial |
Tensile strength | ≥85600 psi |
Yield strength | ≥41300 ksi |
Poissons ratio | 0.299 |
Elongation at break | ≥40% |
We could do solution treatment and ageing treatment for 317LN springs as per the requirement of the clients.
We could supply inspection certificate of 317LN springs by third party,like TUV,DNV,GL,BV,SGS and so on
In order to control the quality of 317 LN springs, we have following inspection equipment:Magnetic Particle Flaw Detector,Hot Coil Spring Production Line.Fatigue Testing Machine,Hardening Furnace,Optical Emission Spectrometry,Spring Coiler,Salt Spray Test Machine,Shot Blaster Machine,Automatic Spring Coiler,Electric Temper Furnace,Electric Temper Furnace,Automatic Spring Coiler,Pressure Testing Machine20mm CNC Spring Coiler,Spring Grinder,Pressure Testing Machine
Our 317 LN springs are widely used in chemical processing, pollution control, pulp and paper production, and treatment of industrial and municipal waste,gas turbines, rocket motors, spacecraft, nuclear reactors, pumps, and tooling and so on
Please send us the drawing of 317LN springs that you need, we are glad to quote the best price for your side.
