1144 What is the material? 1144 is commonly known as carbon free cutting steel easy to iron. Where the 1144 easy to iron well - Suzhou Gabriel billion Metal Spot price sales 1144 easy to iron, 1144 rod, easy car rods 1144, 1144 low carbon free cutting steel, high carbon rod 1144, 1144 Environmental cutting steel, hexagonal rods cutting 1144, 1144 and other quality imported easy to iron cutting steel, full specifications, superior performance, reasonable price, the spot wholesale and retail. Product performance and advanced uses of cold extrusion process allows easy cutting of steel product surface is smooth and bright, due to the addition of steel sulfur, phosphorus, lead, cadmium, selenium, tellurium and other cutting elements, the cutting resistance of steel decreases, while easy Since the cutting characteristics of the element itself and the compounds formed by the lubricating effect of reducing the wear of the cutting tool, thereby reducing the surface roughness of the workpiece, the tool life and improved productivity. Due to easy to iron has excellent cutting performance is often easy for machines and automatic cutting machine. Used as machine screws, nuts, bolts, tie rods ball screw, oil pump drive gear, screw, rod, rack and the spline shaft, and other watch parts. Chemical composition of carbon: 0.40 to 0.48 Mn: 1.35 to 1.65, S: 0.24 to 0.33, P: ≤0.04 mechanical properties of tensile strength (MPa) (hot-rolled) 590 to 735; (tempering condition after cold drawing) 590 ~ 785, elongation (%) (hot-rolled) ≥14; (cold rolled) ≥17, section shrinkage (%) (hot-rolled) ≥20, the hardness value of up to 160 ~ 190HB.
