Cobalt-chromium alloy used in pressurized water reactor (PWR) systems due to its excellent corrosion and wear resistance, radiation resistance, strength, and resistance to thermal fatigue. These properties ensure safe and reliable operation of PWRs, making cobalt alloy an essential material in nuclear power generation.

On Jan. 7th, there is a celebration to celebrate last year's achievements in SYTOP.

Some of our customers will test the products via Brinell hardness tester, Vickers-hardness tester and Handheld hardness tester. Actually these are not accurate because the measurement principle conversion method is not special for cobalt alloy, so there must be some deviation.

Recently, cobalt prices have fluctuated greatly, the prices of products in the market may also vary greatly. There will also be many not actually cobalt products or reducing cobalt content and reducing costs. Then to know the way how to test the materials and products is very important.

Cobalt-based alloys usually are described as wear-resistant, corrosion-resistant and heat-resistant alloys. Many of the alloy's properties arise from the crystallographic properties of cobalt (especially its response to stress), the solid solution strengthening effects of chromium, tungsten and molybdenum, the formation of metal carbides, and the corrosion resistance imparted by cobalt to chromium. Typically, softer and harder compositions are used for high-temperature applications, such as gas turbine blades and strips. Harder grades are used to resist wear.

alloy L605, also called Haynes 25, UNS R30605, has given good service in many jet engine parts and gas turbine engine components.
