Round Link Chain - 25 Mnv Material, 30 Mm Diameter, 120 Mm Pitch Length, Grade 60-100 | Durable, High Strength, Wear Resistant, Fatigue Strength

Loaded with vast industrial knowledge and expertise, we have emerged as a major Exporter, Manufacturer & Supplier of Round Link Chain in Qingdao, Shandong, China.
Purpose: round link chain product applicable range is wide, such as lifting chain, the chain of mining, Marine chain, bundling chain, chain of furnaces, slag chain, lifting chain, decorative chain, etc., the most commonly used with lifting chain and chain for mine. Hoisting ring chain intensity from low to high divided into level 60, 70 grade, 80 grade, 100 grade, 100 grade. Mine ring chain is divided into class B and class C, D chain, D. Now commonly used material is 25 MnV, this material can adapt to the request of the general conditions; The best lifting 100 level and mine C level, generally with 23 mncrnimo54, both in material and manufacturing process is more complex, the cost is relatively high, ring chain special carburizing and quenching treatment on the surface, has high surface hardness at the same time, keep the heart of high tenacity, make the chain has the characteristics of high wear-resistant high fatigue strength. Types and meanings: round link chain products, specifications are generally represented with phi M * N, such as the phi 30 x 120 said the chain bar is 30 mm in diameter, pitch length to diameter( in the circle) is 120 mm.
