Mold Steel
First of all, thank you for coming. If you have the intention to purchase certain steel products from our company, you can make inquiries about certain materials through our company's contact information. Our company will check and give you a quotation based on the certain steel materials and specifications you require.
Below, our company's main product mold steel series, for other information, please consult [ ] The punching die is designed to meet the urgent needs. Its composition design adopts the principle of high carbon multi-element small amount alloying, using sulfur as an easy-cutting element. The chemical composition and properties of steel have been introduced in the second section of Chapter 1, and here we will further introduce the use.
Chemical composition and phase transformation point
Using high carbon multi-element small amount alloy, with sulfur as the easy cutting element, the chemical composition of steel is shown in the table

br/> br/> br/> br/> br/> br/> < br/> Characteristics
The heat treatment process is simple, the hardenability is good, the diameter is above air-cooling quenching, the air-quenching hardness is 0, and the heat treatment deformation is small. When quenched at ~°C and tempered at ~°C, the total axial deformation rate is < and the total radial deformation rate is <.
The cutting performance is good and the annealing hardness is ~. During cutting, the processing hours can be shortened by more than 1/2 compared with ordinary tool steel. In the hard state ~, using high-speed steel or carbide tools for turning, milling, planing, boring, and drilling is equivalent to the cutting performance of carbon steel in the quenched and tempered state, with a hardness of about 0, and is far better than the cutting performance of annealed steel with a hardness of about 0.
The mirror grinding and polishing properties are good and the same grinding process is used. Its surface roughness is lower than that of general alloy tool steel, and the minimum surface roughness is .
Good surface treatment performance and good nitriding performance. Generally, the nitriding layer is as deep as boronizing and has strong adhesion.
