GT1215S free cutting steel

GT1215S free cutting steel is a kind of alloy steel material specially designed to improve the efficiency of cutting processing. By adding cutting elements such as sulfur and phosphorus, it significantly optimizes the cutting performance of the steel and has become an indispensable important material in the current field of mechanical manufacturing.

The main components of GT1215S free cutting steel include carbon, manganese, sulfur, and phosphorus, etc. Among them, sulfur element forms manganese sulfide inclusions with manganese and iron in the steel. These inclusions can interrupt the continuity of the base metal. During the cutting process, they promote the formation of chips with a small and short curling radius, making them easy to remove, reducing tool wear, decreasing the surface roughness of the processed workpiece, and increasing the tool life. Phosphorus element is dissolved in ferrite. An appropriate addition can improve the hardness and strength of the steel, but an excessive amount will reduce the toughness. The synergistic effect of these elements endows GT1215S free cutting steel with excellent cutting performance.

The product performance of GT1215S free cutting steel:

1.Cutting performance: GT1215S free cutting steel has small cutting resistance, and the chips are easy to break and remove, thus reducing the surface roughness of the workpiece and increasing the tool life and production efficiency. This makes it very suitable for processing on automatic machine tools and enables high-speed and efficient cutting processing.

2.Mechanical properties: This steel has high strength and good plasticity, and can be processed by deep drawing, cold heading, stamping, etc., meeting the processing requirements of various complex parts.

3.Environmental protection: Compared with some other steels, GT1215S free cutting steel does not contain lead or other harmful substances, and is an environmentally friendly material, which meets the requirements of modern industry for green production.

GT1215S free cutting steel is widely used in multiple fields due to its excellent cutting performance and mechanical properties:

Mechanical manufacturing: It is used to make standard parts used in instruments and meters with small stress but strict requirements for dimensions and surface finish, watch parts, automobiles, machine tools, and various other machines, such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seats, etc.

Electroplating industry: Due to its accurate precision and good surface condition, the products can be directly used for electroplating processing, such as sandblasting, bending, drilling, etc. They can also be directly electroplated after precise drawing according to actual requirements, saving a lot of time and the cost of processing machinery.

Other fields: It is also widely used in multiple fields such as furniture manufacturing, metal utensils, small hardware parts, and auto and motorcycle parts.

GT1215S free cutting steel, with its excellent cutting performance, mechanical properties, and environmental protection, is playing an increasingly important role in the field of modern mechanical manufacturing. Whether it is to improve production efficiency, reduce costs, or meet the processing requirements of high precision and high surface finish, GT1215S free cutting steel is an ideal choice.
