G80 Alloy Steel Lifting Chain En818-2
Grade 80 chain is a heat-treated alloy steel designed for high strength for overhead lifting and tie down applications. It is the most economical of the three chain grade types that are suitable for overhead lifting (grade 80, grade 100, grade 120). Grade 80 chain makes a versatile, yet rugged option for a variety of applications, including overhead lifting. The high quality alloy steel goes through a special induction heat treatment process, increasing elongation and strength properties.
Advantage: Sample available(To check quality), Customized design(logo stamping), Different packaging(jute bag, plastic wheel, iron drum, wooden case), Short lead time, Multiple payment method(T/T, LC, Paypal, Alipay).

Cautions:
Never use overload.
1:FORMING: Link shape and V notch check required during the full procedure. Dimensions check required.
2:WELDING: The weld was produced using the resistance butt processes and positioned in the centre of one leg of the link. It was smoothly finished all round. The links and welds shall not show fissures, notches or similar faults that are detrimental to the chain after welded. The diamater of the material at the weld was nowhere exceed the dimenstions requirements and not.less than the diameter of the material of the link.For smooth welded chain, fins caused by welding will be removed and the weld will be smoothly finished all round. The positioning of the weld at the centre of the straight barrel and the tolerances imposed on protrusions at the weld will provide the required clearances.
3:CALIRATING: Dimension check required for each calibration. Proof load on calibration shall be record for each batch.
4:MARKING: Chain Calibration Machine. Tow series available for 5mm to 16mm chain diameter marking/stamping. One key start. Adopt PCC control system with automatic-stop function when encounter fault, Reasonable mould design. Add self-weight function for the machine to increase the operational stability.
Pneumatic marking system which can also mark on two links at the same time.
5:HEAT TREATMENT: All the chain has been intermediate-frequency heat treated, it was hardened from a temperature above the AC3 point and tempered before being subjected to the manufacturing proof force.
