Spring Manufacturer Alloy Heavy Duty Flat Compression Spring

It is a kind of hardware fittings with spiral geometric shape formed by wire, so it is more difficult to harden and strengthen the work than the plane hardware fittings (such as stamping parts). In addition, it is also necessary to strictly control the hardening effect of the cross section of the compression spring, so as to fully control the fatigue fracture resistance of the decompression spring after use.

Compression spring is a more general hardware accessories,
A Name -B Dimensional accuracy and rotation -C Standard number -D Material number -E Surface treatment
A Name: compression spring
B Dimensional accuracy and rotation: D ×D2×H0- precision rotation
C Standard number : GB2089-80
Note: spring rotation should be indicated for left rotation, but not for right rotation
When it is required to check the inner diameter of the spring, add the "D1" sign after the value of D2.
Marking example: material diameter 1.2mm, spring middle diameter 8mm, free height 40mm, load, outer diameter, free height and axis line and both ends of the ring perpendicularity accuracy is 2, material for carbon spring steel wire GROUP ⅱ A, surface galvanized left spring
Pressure spring 1.2×8×40-2 left GB2089-80· ⅱ A-D ·Zn
Material diameter 3mm, spring diameter 20mm, free height 80mm, load, inner diameter, free height and axis line and both ends of the ring perpendicularity accuracy is 3, the material is carbon spring steel wire ⅱ group, surface oxidation treatment of dextral spring
Compression spring 3 x 20 x 80 GB2089 d1-80
