There are many types of stainless steel balls, and different materials determine different characteristics and use. Even therefore, the price of steel balls will vary greatly. We have to choose according to the environment in which the steel balls are used, the product quality requirements for the use of steel balls, etc. A stainless steel ball of suitable material. Below, briefly introduce the concept of stainless steel and the characteristics and uses of various stainless steel balls.
Stainless steel ball 420/420C
Characteristics: Like 440C and 440, 420C has stronger anti-rust and anti-corrosion performance than 420 stainless steel balls. 420/420C stainless steel balls are also representative of martensitic steel, also called stainless iron, which is magnetic and has better anti-corrosion properties. Rust performance, high hardness HRC50-55.
Uses: 420/420C stainless steel balls are usually used in industries that require high precision and anti-rust performance: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, handicrafts, valves, petroleum, etc.
Stainless steel ball 317L
Features: 317L (00Cr19Ni13Mo3, UNS S31726) alloy is austenitic stainless steel based on molybdenum. Compared with the conventional 300 series chromium-nickel austenitic stainless steel, it has stronger resistance to chemical corrosion. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength, and high-temperature resistance. It is low carbon grade or L grade, this grade has anti-sensitization performance during welding and heat treatment.
Uses: 317L steel has good seawater resistance and SCC resistance compared to 316L. It is used in ships, chemical products, and other chemical equipment that require high corrosion resistance.
Stainless steel ball 316/316L
Features: Stainless steel ball 316/316L is also austenitic steel, which is currently the most high-end steel ball industry, HRC≤26, most suitable for industries with high anti-corrosion requirements, all performances are better than 304 stainless steel balls, 316L stainless steel The ball is softer and tougher than 304, so it is usually used for human body accessories.
Uses: 316/316L stainless steel ball is a relatively demanding product, usually used in special industries such as medical equipment, chemical industry, aviation, aerospace, lithium battery cells, perfume bottles, sprayers, valves, nail polish, human accessories, mobile phones Electric board, etc.
