The anti rust stainless steel ball contains 12.5% or more of chromium when it is used, and has a high resistance to corrosion of chemicals (acid, alkali, salt). Stainless steel does not rust, but is not easy to rust. The principle is that by adding chromium, a layer of dense tissue of chromium oxide is formed on the surface of the steel, which can effectively block the re-contact of the steel and the air, so that the oxygen in the air cannot enter the steel, thereby preventing the steel from being produced. The effect of rust.
The anti rust stainless steel ball has a hardness of 56-58 degrees, has magnetic properties, good corrosion resistance, good wear resistance and toughness. Applications: Mainly used in bearings, stamping/hydraulic parts, valves, seal refrigeration equipment, aerospace high precision Mechanical parts, crafts, toys.
Anti rust stainless steel balls are commonly used in industries where high precision and rust resistance are required: aviation, aerospace, bearings, motors, high-precision instruments, valves, and petroleum. Metallographic organization belongs to martensitic steel, and the production process is relatively high. There are few enterprises that can produce stainless steel 440C in China, so enterprises that can produce 440C materials are often praised as special stainless steel. The heat treatment process is complex, easy to crack, and has high precision requirements. It is a hard stainless steel ball in the steel ball: HRC≧58. The hardness is close to the bearing steel ball, but it has stronger anti-rust and anti-corrosion performance than the former.www.wxjnsteelball.com
