Material introduction

1. Excellent Flexibility .

Parts are made from super quality spring steel , this kind of material has good elastic deformation , which can keep the original shape long time even there is much loading during service .

2. High Strength .

Parts were formed and then must be quenched in 400 degree x 15 minites and anti-fatigue is up to 240 Mpa .

3.Perfect stability .

Inside components and instructure of part are reformed after quenching , keeping this status long time , and that make part satisfied expect requirements .

4. Good heat resistance .

Spring steel part can be worked smoothly under 500 degrees surroundings , so , which is the ideal choice for part that in bolier , car , steam valve etc .

5. Low cost .

As spring steel is easy to make and full automated production ,

6. Easy to oparation .

Simple structure and strict tolerances.

7. Nice appearance .

Parts were plated after forming and also can be coated different colors based on request of fittings .

8. Enviroment friendly .

All chemical elements and surface treatment are meet for the relative standards .eg , GB , ROSH etc .
