K20/K30 Tungsten Steel Plate With High Wear Resistance And Hardness
K20/K30 Tungsten Steel Plate With High Wear Resistance And Hardness
Tungsten Steel Plate are mainly made of WC tungsten carbide and Co cobalt powder mixed by metallurgy method after milling, ball milling, pressing and sintering, the main alloy composition is WC and Co, tungsten steel plate for different purposes in the content of WC and Co is not consistent, the use of a very wide range. Tungsten steel plate is one of the many materials of tungsten steel, because its shape is rectangular plate (or square) named, also known as tungsten steel plate.

The process flow of Tungsten Steel Plate
Powder making → according to the requirements of the use of formula → wet grinding → mixing → grinding → drying → sieving → after adding molding agent → drying → sieving after making the mixture → granulating → pressing → forming → sintering → forming (blank) → flaw detection inspection → packaging → storage.
Performance Characteristics of Tungsten Steel Plate
Tungsten steel parts have excellent rigidity, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high-temperature oxidation), low impact toughness, low expansion coefficient, thermal conductivity, electric conductivity and iron and its alloys similar characteristics.
Application of Tungsten Steel Plate
Tungsten steel parts are mainly used for making high-speed stamping die and multi-station progressive die of blanking copper, aluminum, stainless steel, cold rolled sheet, EI sheet, Q195 sheet, SPCC, silicon steel sheet, hardware, standard parts, upper and lower punch, etc. It is also an excellent material for making high-temperature resistant parts, wear-resistant parts, anti-shielding parts and corrosion-resistant parts. Suitable tungsten steel plate should be selected according to the specific use.
