Machining Low- and Medium-Carbon Steel Alloys: Cut these common and useful steels efficiently with chip breaking solutions

摘要

Low-carbon and medium-carbon steels form the backbone of virtually every shop's operations in their general engineering applications and fabricated parts. What defines them is the percentage of carbon in the steel; 0.15 to 0.30 percent for low-carbon "mild" steel and 0.30 to 0.60 percent for medium-carbon steel. According to cnccookbook. com, mild steels are common with broad uses because of their good machinability and weldability combined with low cost. Most grades are available cold formed or hot rolled. Mild steel is used for parts that may be case hardened, but whose core strength is not critical. Given the material's favorable cost, manufacturers often use it for high-volume parts such as screw machine parts, shafts, lightly stressed gears, and hard-wearing surfaces, pins, and chains. Other applications include weldments, gear boxes, drivetrains, and general engineering parts.
