GX30CrSi6 as a kind of mould steel, is applicable to various molds that require high wear resistance, such as hot extrusion dies, hot forging dies and so on. It has higher working hardness, better heat resistance and excellent toughness, so it is widely used in plastic, glass, powder and other industries for making various molds.
GX30CrSi6 is a high-carbon high-chromium low-alloy steel. It is the highest wear-resistant steel in Chinese die steel series. It has high abrasion resistance, high tempering stability, and has good comprehensive performance after tempering and quenching. It has an approximate composition of 0.2% C, 1.44% Si, 1.9% Mn, 1.25% Cr, 0.35% Mo, 0.35% V and 0.22% Al. The content of impurities such as P and S is less than 0.03%.
This high-hardness type steel is suitable for both forging and quenching and tempering. The tempering temperature is 510℃-640℃, which can be adjusted according to the application. The process of GX30CrSi6 is usually quenching and tempering. After quenching, the hardness of GX30CrSi6 is about HRC48-54, and after tempering for 2-4 hours, the hardness HRC60.
GX30CrSi6 mould steel can be used for making various high wear-resistant molds, such as high temperature extruding dies, hot forging dies, etc. Its wear resistance and comprehensive performance can meet the high requirements of various molds. In addition, GX30CrSi6 mould steel also has good thermal fatigue resistance and high temperature strength, so it is suitable for making some complex molds.
GX30CrSi6 mould steel has good thermal shock resistance and thermal conductivity. This is also related to its heat resistance, so it can be used to manufacture plastic molds and molds for manufacturing powder materials. Its high hardness and wear resistance can be used to make plastic molds, die-casting molds, blow-molding molds, extrusion molds and powder metallurgy molds.
In the production of GX30CrSi6 steel, the strict process control method must be adopted to ensure the performance stability of the steel. In the production, first use advanced and scientific heating methods to ensure the uniformity of heating and full and uniform austenitization. After austenitization, it should be uniform cooling and tempering. During thermal processing, reasonable parameters should also be selected. In addition, the testing and inspection should be strengthened to ensure the quality of the products.
In conclusion, GX30CrSi6 is a kind of wear-resistant steel with strong wear resistance, good thermal fatigue resistance and high temperature strength, which is widely used for making various molds. The production process of GX30CrSi6 alloy steel should be strictly controlled in order to obtain good performance. Thus, GX30CrSi6 is a kind of high wear-resistant mould steel with good comprehensive performance and stability.
