The hardness of the teeth is an important factor

The mechanical properties of low carbon steel bucket teeth were evaluated by tensile and hardness tests. Tensile tests were performed on three specimens for each composition, using an ALSA KTM 1000 universal testing machine at a strain rate of 10-4 s-1. The yield stress was calculated from 0.2% proof stress in uniaxial tension. Each specimen was tested three times, and large deviations due to voids and cracks were excluded from the analysis. Rockwell-C hardness precision casting factory was measured with a Digirock BMS 200-RB hardness tester. Each specimen was measured for four points. The mean value of each specimen was calculated from these measurements.

High chromium cast iron bucket teeth are used to increase the wear resistance of metal cutting tools. The teeth are designed to work effectively with medium hardness or soft ore. They can be fabricated with various materials, including carbon steel and high manganese steel. However, most bucket teeth of excavators made in China are made from medium carbon steel. It is better to use a low alloy steel for bucket teeth than to use a high alloy steel.

The hardness of the teeth is an important factor in choosing the right material for excavator bucket teeth. A harder material is better for impact and wear resistance, thus extending the life of the tool. High manganese steel and low carbon alloy steel are two materials that are inexpensive and have good toughness. High chromium cast iron is a mid-range material with good toughness and impact resistance, but isn't as strong as high manganese steel.

The process of producing bucket teeth involves three steps: the making of a wax pattern, the production of a grounding piece, and the application of a heat treatment. The wax pattern has to be highly accurate and have a high surface finish. CFS wax models are recommended for this application because of their low melting points, good surface finish, and high strength and light weight. The wax patterns are then stuck to the sprue gating system.

How to prevent rust  for precision casting parts

Parfect precision casting foundry is a set of investment casting, investment casting equipment, technology transfer, equipment accessories sales in one of the high-tech companies, and then to share with you is the precision casting of rust prevention knowledge. Corrosion or discoloration of metals or alloys in the atmosphere due to oxygen, water, acid, salt, and moist air is known as rust or rust. 

For this reason, the investment of the investment casting is usually in the medium term. Rust prevention method, usually used water rust or rust proof oil. No matter which method is used to prevent rust, the casting must be washed in advance, to remove the dirt surface, and promote the formation of passive film. Composition, temperature and use of washing liquid. After washing the casting with hot, dry compressed air drying, then rust treatment. We are willing to "preferential prices, excellent quality, quality service" with you close cooperation, warmly welcome Chinese and foreign businessmen to seek common development and create a win-win situation.
