Recently, some customers are consulting us whether the quality of free-cutting steel can be heat-treated to improve the strength of this type of steel is mainly for automatic machine tools for high-speed cutting of steel used in the production of mechanical parts. Characterized by carbon, manganese, silicon composition are general carbon steel content, but the sulfur, phosphorus content is several times higher, such as sulfur up to 0.30%, phosphorus up to 0.15%, due to sulfur, phosphorus content of the increase in the high, increasing the cutting performance of the steel, and thus greatly improve the cutting speed of the machine tool. This steel is mainly used for the production of some less important mechanical parts, such as screws and nuts, etc., rarely need to be heat-treated.
The common 1215 free cutting steel, like ordinary steel, can be heat treated for various purposes, but because of its high sulfide inclusions, it is necessary to control the forging temperature a little more strictly, and it is generally not on its not tempering heat treatment, there will be uneven hardness.
This type of steel to improve the strength is generally realized through cold deformation, carbon and nitrogen co-penetration. Changzhou Tenjan Steel Tube Co., Ltd. is a factory with 20 years of experience in seamless steel pipe production, and accepts small quantities of customized special seamless steel pipes and profiles from customers. In the past two years, through technological advances, we can now produce cold-drawn 1215 material profiles and seamless steel pipe, which can be produced in the following specifications: OD 20-70mm, wall thickness 2-13mm. welcome to inquire.
