Cobalt alloy has excellent high-temperature, wear and corrosion resistance at the same time. STP alloy rods are typically used in high-temperature and high-wear applications, such as aerospace, oil and gas, and power generation industries. Cobalt alloy rods can be used in a range of applications, such as valve seats, cutting tools, bearings, and turbine blades. These rods are typically made by melting and casting the cobalt alloy into a rod shape and finishing the surface to the required size and shape.

STP alloy rods have several advantages over other materials. They are highly resistant to wear and corrosion and withstand high temperatures and pressures. They also have good mechanical strength and can maintain their properties at high temperatures, making them ideal for use in harsh environments.

Overall, STP alloy rods are a reliable and durable choice for applications that require high wear and corrosion resistance and high temperature and pressure resistance.
