Carbon steel elevator chain , Iran

Steel elevator chains are manufactured from high-strength alloy steel grade 80T or 100T 800-1000 N/mm² tensile strength. Standard bar diameters range from 7 to 32 mm with a pitch length of 5 times the bar diameter. Minimum breaking force varies from 65 to 1800 kN depending on chain size. Working Load Limit is calculated with a safety factor of 7:1 for critical lifting applications. These chains undergo controlled quench and temper heat treatment to enhance fatigue resistance. Ultrasonic non-destructive testing is performed along the entire chain length to detect internal defects.

The chain structure features resistance welded links with full circumferential flash butt welding. Links are designed in an elongated oval shape with a 90-degree internal attachment angle for axial load bearing. Post-heat treatment surface hardness is maintained between 34 to 40 HRC Rockwell C. Surface coating is applied via hot-dip galvanizing 75-100 microns or electroless nickel plating. Suitable operating temperatures range from –30°C to +200°C without significant mechanical degradation. Production complies with international standards ISO 4347 Class T and DIN 764 for elevator and industrial hoist applications.You can order and buy Carbon steel elevator chain from Iran by contacting us through whatsaap and email.
