Product Description

Product name: Cobalt Chrome Round Bar

Material: Stellite, Cobalt-Based Alloy

Size: OD 6mm x 1000mm

Application: Alloy round bar for oil and gas industry

Cobalt-based alloys are a series of cobalt-chromium-tungsten alloys with good erosion resistance and wear resistance. Its wear resistance is determined by chemical composition, not the product of heat treatment or other hardening mechanisms. Has wear resistance, corrosion resistance and high heat resistance. Widely used in oil and gas, machinery, wood cutting, automotive, paper, food processing and other industries.
