Hongxin steel pill, trustworthy! Welcome to the Hongxin official website

　　The microstructure of Hongxin steel shot is composed of ferrite and austenite stainless steel grain. When melting, it solidifies from liquid phase to complete ferrite structure. About half of ferrite grains are transformed into austenite grains.

　　It is suitable for applications requiring high strength and excellent corrosion resistance. Combined with the improved resistance to stress corrosion cracking, pitting and crevice corrosion, the corrosion resistance is almost twice that of other steel shot. It is twice as tough and ductile as ordinary austenitic or ferritic stainless steel shot casting. It has better toughness and ductility. The corrosion resistance mainly depends on the composition and corrosion resistance. The content of chromium, molybdenum and nitrogen is the most important.

　　With a series of corrosion resistance, stainless steel shot shows a very good resistance to stress corrosion cracking. The content of nickel and molybdenum is lower than that with similar corrosion resistance. Due to the lower alloy content and lower cost, in addition, due to its increased yield strength, the section thickness can be reduced and the cost can be significantly reduced. Stainless steel pellets can be obtained in many industries, such as automobile, oil, natural gas and food equipment. More design flexibility can be obtained. It can be flexibly configured according to the needs, which helps to configure in a solid and repeatable way. This flexibility also allows for faster changes from design time to a shorter time to see the finished product.

　　Manufacturing flexibility: the use of stainless steel balls can select different chemical components according to the engineering requirements, provide a wider range of physical and mechanical properties, help to provide additional versatility, variable weight range, according to the needs, can manufacture stainless steel balls according to various weights, in precision manufacturing, food machinery, doors and windows, oil and gas, power generation, etc., design flexibility can Provide alloy for use that may affect configuration and strength, and design complex custom molds.
