How much is Foshan electroplated steel ball?

Jinshun mainly produces 316L stainless steel ball, 304hct stainless steel ball, copper ball, stainless steel hollow ball, stainless steel polishing ball, stainless steel UFO ball, plastic ball, alloy ball, carbon steel ball, glass ball, aluminum ball, titanium ball, stainless steel bottle ball Introduction of plastic milk Wang Lei: "For enterprises, it is necessary to achieve a control bottle ball and electroplated ball for the VOC of the whole vehicle, and steel balls made of 440C 420C Cr15 and other materials for high-precision sealing. The raw materials are domestic high-quality manufacturers such as Yongxing special steel, Baosteel, Dalian special steel, Great Wall special steel, etc. the specification of the steel balls is 0.5mm-60mm, and the grade is g. non-standard steel balls can be customized. How much are Foshan electroplated steel balls? Jinshun hardware, while producing high, medium and low carbon steel, bearing steel, and drilled balls, which are widely used in cosmetics Metering pumps, aerospace industry, automotive industry, spray, stainless steel bearings, handicrafts, therapeutic instruments, motorcycles, bicycles and other supporting products

the standard specifies the size of the steel ball. How much is the plated steel ball in Foshan_ Jinshun hardware, technical requirements, marks, measurement and inspection methods, inspection rules, packaging and storage. The standard applies to steel balls for rolling bearings and commercial carbon chromium bearing steel balls. Based on the business tenet of "customer first, how much is Foshan electroplated steel ball _ Jinshun hardware, reputation first", Lida has produced steel balls and bearings, which have been praised by many enterprises and manufacturers at home and abroad, and established a good business relationship with customers. All employees of the company sincerely welcome domestic and foreign merchants to negotiate business, invest and cooperate, and create brilliance hand in hand

the differences between the two are as follows:

1. The molybdenum content in 316L stainless steel is slightly higher than that of 316 stainless steel

2, the time limit of the C content of 316 is 0.08%, while the C content of 316L sometimes adopts the upper limit of non-ferrous metals and special metals such as aluminum alloy to reduce the amount. The higher the C content, the simpler it will cause intergranular corrosion

the lower limits of tensile and yield strength of wise men 3 and 16 are 515 and 205mpa respectively, and the lower limits of tensile and yield strength of 316L are 485 and 170Mpa respectively

4. Heat resistance. Within the temperature range, it is best not to connect 316 stainless steel, but when 316 stainless steel is used outside this temperature range, it has excellent heat resistance. 316L stainless steel has better function of resisting carbide precipitation than 316 stainless steel

5. Heat treatment. Annealing in the temperature range of degrees, then rapid annealing, and then rapid cooling. 316 stainless steel cannot be hardened by overheating

6. Welding. 316 stainless steel has excellent welding function and can be welded by all standard welding methods. In order to obtain the best corrosion resistance function, the welding section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post weld annealing is not required

The corrosion resistance and high temperature strength of

316 stainless steel have been greatly improved due to the addition of Mo element. The high temperature resistance can reach degrees, which can be used under harsh conditions

stainless steel 316 is mainly used for pulp and paper equipment, heat exchangers, dyeing equipment, film washing equipment, pipelines, and materials for the exterior of buildings in coastal areas. In 2013, it was also used in the field of solenoid valves, mainly for shells, clamps, spheres, valve bodies, valve seats, nuts, valve stems, etc

stainless steel is generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and deposition hardening stainless steel, or into chromium stainless steel and nickel stainless steel

316 stainless steel has excellent welding function. All standard welding methods can be used for welding. 316cb, 316L or 309cb stainless steel filler rods or electrodes can be selected for welding according to their use. In order to obtain the best corrosion resistance function, the welding section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post weld annealing is not required.

304 stainless steel can be forged

at present, the thickest sheet metal in the market is 65mm

above other thicknesses, it needs to be forged and formed, and the forged raw skin is black

304 stainless steel is a common raw material in stainless steel, with a density of 7.93 g/cm3, which is also called 18/8 stainless steel in the industry. High temperature resistance of 800 degrees, with good processing function and high tolerance, it is widely used in industry, furniture decoration profession and food medical profession

common marking methods in the market include 00Cr19Ni10 and SUS304, of which 00Cr19Ni10 generally indicates the standard production of national standard, generally indicates the standard production of ASTM, and SUS 304 indicates the standard production of Japanese standard

304 is a universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive functions (corrosion resistance and formability). In order to adhere to the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a brand of stainless steel produced according to American ASTM specification

one possibility is false

another possibility is to encounter chemicals with particularly strong corrosivity. "304 stainless steel" is not sure that it will not rust, but it is more corrosion-resistant than ordinary steel

stainless steel is the abbreviation of stainless and acid resistant steel, and the steel resistant to weak corrosive media such as air, steam, water or stainless steel is called stainless steel; The steel resistant to chemical corrosion media (acid, alkali, salt and other chemical etching) is called acid resistant steel

their corrosion resistance is different due to the difference in chemical composition. Generally, stainless steel is not resistant to chemical medium corrosion, while acid resistant steel is generally rust free. The word "stainless steel" refers not only to a single kind of stainless steel, but also to more than 100 kinds of industrial stainless steel. Each kind of stainless steel developed has outstanding functions in its specific application fields

the key to success is to clarify the use first, and then determine the correct steel grade. There are usually only six kinds of steel related to the application field of building construction. They all contain 17-22% chromium, and the better steel also contains nickel. Increasing molybdenum can further improve atmospheric corrosion, especially the corrosion resistance of chloride containing atmosphere
