High Tensile Round Link Alloy Steel Chain For Elevator Buckets

The materials of round link steel chain is  produced by the super alloy steels specially designed by steelworks, with higher Mn chemical content for 2H, nad Nicr and NiCrMo alloys for other types.

To gurantee the best working performance, this chains of all types are subjected to over-refined ,quenched and tempered, also comprising high depth carburizing. The welding is automatic butt process, the tensile strength is all passed proof load and breaking load.

The results of our manufacturing process are:

• Produced with fine grain and very tough core, with a gradual transition from the hardened to the inner area;
• Breaking forces equal or higher than those established by the DIN 764-766 grade 2 or 3 standards;
• High resistance to wear and tear;
• Carburising depth equal to a min. of 0.1 diameter up to 0.21 diameter;
• Extremely high surface hardness, even over 64 HRC (800HV30);
• Excellent performance even in demanding applications, for example the transport of hot and/or highly abrasive material (clinker, slag, pozzolana, etc.), high speed, high dynamic load or significant fatigue stress.

Chains with chemically very stable structure are also available. They are useful to withstand chemical aggression, for example during the transport of sulphur-containing wet coal. It was widely used in lifting , sling, rolling ,lashing,etc.

Qingdao Maxim International Import And Export Co.,ltd also supplying chains links, coupling links, chains sling assemblings, lifting hooks, etc, welcome to inquiry.
