Introduction
Free-cutting steel is an environmentally friendly material and does not contain lead or harmful substances to the environment. It has good machinability. It is suitable for general electroplating shafts, cutting materials and general parts. Due to the precise surface condition, Good free-cutting steel products can be directly used, such as spraying, sanding, bending and drilling, or they can be finely drawn according to actual requirements and then electroplated directly, eliminating a lot of machining time and saving the cost of configuring processing machinery.
Usage
Mainly used to make instruments, watch parts, automobiles, machine tools and other various machines that have strict requirements on size and finish and have small stress. Standard parts with relatively low mechanical performance requirements such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seats and machine tool screws, plastic molds, surgical and dental procedures, etc.

Delivery status
Direct from the steel factory. Delivery is round steel black bar also called hot rolled steel. Easy-to-cut steel cold-drawn polished rods: the hardness can reach up to ~ eliminating the cost of heat treatment and can be processed directly. Polishing rod: positive and negative surface roughness
Advantages and scope of use
Easy-cut steel with high sulfur content has good cutting performance, high plasticity and higher strength.
Advantages
. Diversity of shape specifications: Free-cutting steel with different cross-sectional shapes and different specification tolerances is cold drawn by designing molds of different shapes. Angles can be right or rounded. .High precision: Use high-quality carbide molds to ensure accurate and uniform tolerances. .Smooth surface: The advanced cold extrusion process makes the surface of free-cutting steel products smooth and bright. .Significant material saving: The cold drawing process is to cold-extrude and deform the raw materials to achieve the required shape, specifications and tolerances. The consumption of raw materials is very small. Compared with the materials consumed by machining and cutting with traditional lathes, the materials and time saved are free-cutting steel. It is very considerable, especially when the amount of materials is large, the material cost savings are even more significant. .Saving of processing time and processing machinery: Due to the accurate precision and good surface condition, easy-cut steel products can be directly used for spraying, sanding, bending, drilling, or can be finely drawn according to actual requirements and then electroplated directly, eliminating a lot of machining time and Save the cost of configuring processing machinery.
Widely used
Mainly used for automatic cutting machine tools to process fasteners and standard parts such as stud bolts, screws, nuts, pipe joints, spring seats, etc. .Mechanical equipment: woodworking machinery, ceramic machinery, paper machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jacks, hydraulic presses, etc. Electrical product components: motor shafts, fan shafts, sewing machine shafts, etc. Furniture: Special Is exporting metal furniture such as coffee tables, chairs, outdoor furniture d. Metal appliances: garden tools, barbecue grill racks, screwdrivers, anti-theft locks, etc. Small hardware accessories: such as guide rails, machine keys, nuts, screws, round nails, hexagonal nails, Octagonal nails and various standard parts of different specifications. Automobile and motorcycle spare parts, etc.
