Grade 80 Alloy Steel Lifting Chain Size 30 mm , Iran

The Grade 80 chain size 30 is a heavy duty alloy chain designed for industrial lifting applications and manufactured according to EN 818-2 standards. The nominal link diameter is 30 millimeters and the chain pitch is approximately 90 millimeters. It is produced from chromium molybdenum alloy steel using quench and temper heat treatment. The minimum ultimate tensile strength is about 800 megapascals. The working load limit is approximately 20 tons in single leg configuration. A minimum safety factor of 4 to 1 is applied. Controlled surface hardness improves wear resistance and service life.

Structurally, Grade 80 chain size 30 links are manufactured using flash butt welding with precise penetration control. Uniform cross section geometry ensures proper stress distribution under dynamic loading. This chain is suitable for operating temperatures from minus 40 to plus 200 degrees Celsius. Dimensional tolerances comply with European standards and elongation is strictly limited. High mechanical fatigue resistance makes it ideal for cranes and lifting slings. The surface finish is typically industrial black or safety coated. Each link undergoes proof load and non destructive testing.You can order and buy Grade 80 Alloy Steel Lifting Chain Size 30 mm from Iran by contacting us through whatsaap and email.
