Bengbu Carbon Steel Double Drum Rivet Specifications (How to Distinguish Carbon Steel and Manganese
1. Non-ferrous metals Non-ferrous metals (such as aluminum and aluminum alloys, copper and copper alloys, etc.) are usually easy-cutting materials. 2. Cast iron The machinability of cast iron is generally better than that of carbon steel. Comparing the machinability of various cast irons mainly depends on the form of graphite, the state of the matrix structure, the composition of the metal structure and the influence of heat treatment. For example: in gray cast iron, malleable cast iron and nodular cast iron, graphite is in the form of flakes, flocs and spheres respectively, so their strength increases sequentially, and the workability decreases accordingly. 3. Carbon steel The machinability of ordinary carbon steel mainly depends on the carbon content in the steel. Low carbon steel has low hardness, high plasticity and toughness, large cutting deformation, high cutting temperature, and difficult chip breaking, so the machinability is poor. High carbon steel has high hardness, low plasticity, and poor thermal conductivity, so the cutting force is large, the cutting temperature is high, the tool durability is low, and the processability is also poor. Relatively speaking, medium carbon steel has better machinability. 4. Alloy tool steel Add certain alloying elements to carbon steel, such as Si, Mn, Cr, Ni, Mo, W, V, Ti, etc., to improve the mechanical properties of the steel, but the processability also deteriorates. 5.
