G200 440C Stainless Steel Ball is one of the steel ball products that Condar can produce. We are a steel ball manufacturer and supplier from China, integrating production and sales. Our products are of high quality, rust-proof and wear-resistant, and can provide a long service life. We look forward to achieving long-term cooperation with you.
G200 440C stainless steel ball is very suitable for some industries with high requirements for rust and corrosion resistance. It also has relatively high hardness and excellent performance. It can withstand high-pressure use environments and has strong wear resistance and toughness.
The steel ball grade of G200 440/440C stainless steel ball is 200. The grade is mainly determined by indicators such as ball diameter variation, spherical error, batch diameter variation, and surface roughness. We will strictly control these indicators in production to ensure that the product can meet your needs and achieve higher quality and precision, which is especially important for industries such as precision instruments and aerospace.
