Steel-bonded Carbide
Steel-bonded carbide is a new type of engineering material. It combines the advantages of steel and hard alloy, which gives it many unique characteristics: high hardness, low proportion, low friction factor, low surface energy, good high-temperature stability. It has been widely applied to many industrial fields because of its attractive physical and mechanical properties. Contact us now to get your quote!

Steel-bonded Titanium Carbide
Description:
AP-7202, AP-7202X and AP-7203 Titanium carbide based chromium-molybdenum steel-bonded carbide is of many attractive features:
low density, high hardness, high wear resistance, high rigidity, good high temperature resistance, good self-lubricating performance, good impact resistance and anti-thermal fatigue resistance, high modulus of elasticity and rigidity, excellent damping characteristics, low coefficient of friction and thermal expansion coefficient, good self-lubricating properties and good resistance to oxidation, corrosion and high temperature with a low heat treatment deformation rate. It is a good rigid seismic tool and parts and can be repaired, welded and machined.
Product core advantages:
1. Core technology of formulating high-end material for wear solution;
2.Standardized manufacturing process and process design;
3. Independent research and development with Applied Polytech;
4. Comprehensive enterprise standards;
Product application areas:
High-end wear-resistant and impact-resistant self-lubricating cold/hot stamping precision dies are widely used in cold/hot heading dies, cold stamping dies, cold/hot extrusion dies, screw extruder elements, shearing dies, blanking dies, forming dies, extension dies, drawing dies, die-casting molds, refractory dies, four-station progressive die in motor industry, potentiometer punch progressive die, E-type silicon steel die, motor fan die, blanking die in electronic industry, cold/hot drawing tube drawing die, and bicycle parts cold stamping die.
Product successful applications:
High-end wear-resistant and impact-resistant self-lubricating cold stamping precision dies have been well tested and verified in the auto parts factory, and their service life has been greatly improved. The service life comparison is shown below.
Application | Concave Die |
|---|---|
Process Material | Stainless steel sheet with 2-3mm thickness |
Service Life with Original Material | Powder metallurgical tool steel S390 stamping precision die: 10,000 times |
Service life with Steel-bonded Titanium Carbide | Cold stamping die made of AP-7203 Titanium carbide based Chromium-Molybdenum steel-bonded carbide: 40,000 times |
Application | Auto parts manufacturer |
Performance Improved with our solution：
1. Service life of cold stamping die made with AP-7203 Titanium carbide-based Chromium-Molybdenum Steel Bonded Carbide is about dozens of times as that of high chromium tool steel die based on our experiment. Due to its good self-lubricating properties, it has better performance in extrusion die applications than cemented carbide, especially in the extrusion of viscous metal materials such as copper alloys and stainless steel.
2. The mold service life of cold stamping die made with AP-7203 Titanium carbide-based Chromium-Molybdenum Steel Bonded Carbide is increased by a dozen of times. Previous refractory molds are mainly manufactured by carbonitriding low carbon steel or cast iron and high chromium cast iron. Cold stamping dies made with AP-7203 Titanium carbide-based Chromium-Molybdenum Steel Bonded Carbide improves the precision of refractory sheets as well as product quality.
