Foshan process steel ball customization

it is not whether the temperature resistance of stainless steel ball 304 raw material is about 200 degrees. There is no problem with 304 raw material

it mainly depends on whether the raw material of the ball core sealing ring in the stainless steel ball valve can reach 200 ℃. The commonly used ball core sealing raw material is PTFE, which can reach 200 ℃. Foshan process steel balls are customized_ Jinshun hardware advocates to choose: cast steel WCB stop valve or stainless steel stop valve! Or stainless steel ball valve (the raw material for ball core sealing needs to be changed to 200 degrees). Dongguan Jinshun hardware and Plastic Co., Ltd. is located in the first industrial zone of Wufang, Gaopo Town, Dongguan, and produces steel balls, steel balls, stainless steel balls, iron balls, iron balls, and copper ball rivets; Bearings; Screws; Hardware special-shaped parts, etc. It is widely used in strollers, guitars, treadmills, mechanical equipment, suitcases and bags. Jinshun has a strong technical force and a strong production lineup. Jinshun has production equipment and Foshan process steel balls are customized_ Jinshun hardware is a perfect testing instrument

304 stainless steel belongs to soft state; Generally speaking, the soft stainless steel refers to the annealed stainless steel. Low hardness and tensile strength

304 stainless steel chemical composition

standard C Si Mn p s Cr Ni (nickel) mo

sus431 ≤ 0.08 ≤ 1.00 ≤ 2.00 ≤ 0.05 ≤ 0.0318 08.25-10.50 -

304 is 1Cr18Ni9

the mechanism of stainless steel rust prevention is that alloy elements form a fine oxide film to isolate oxygen contact and prevent further oxidation. So stainless steel is not "stainless"

316 stainless steel is customized by Foshan process steel ball due to the addition of Mo element_ Jinshun hardware has greatly improved its corrosion resistance and high-temperature strength, and its high-temperature resistance can reach degree, which can be used under harsh conditions

stainless steel 316 is mainly used for paper. For thick wall plastic parts, equipment for pulp and paper making, heat exchanger, dyeing equipment, film washing equipment, pipes, 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 outstanding 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, the welded section of 316 stainless steel needs post weld annealing. If 316L stainless steel is used, post weld annealing is not required.

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 upper limit of C content of 316 is 0.08%, while the upper limit of C content of 316L is 0.03%. The higher the C content, the easier it is to cause intergranular corrosion

3 and 16 have lower limits of tensile and yield strength of 515 and 205mpa respectively, and 316L has lower limits of tensile and yield strength of 44 respectively. Software and hardware: excellent electronic universal testing machine adopts brand computers of 85 and 170Mpa

4. Heat resistance. Within the temperature range, it is better not to connect 316 stainless steel. However, when 316 stainless steel is used outside the temperature range, the stainless steel has excellent heat resistance. The carbide precipitation resistance of 316L stainless steel is better than that of 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 heat treatment

6. Welding. 316 stainless steel has outstanding welding function and can be welded by all standard welding methods. In order to obtain the best corrosion resistance function, the welded section of 316 stainless steel, a fusible and moldable tough material, needs post weld annealing treatment. 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 leather is black

304 stainless steel is a common raw material in stainless steel, with a density of 7.93 g/cm3. It is also called 18/8 stainless steel in the industry. High temperature resistance of 800 ℃, 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 that the product is produced according to the national standard, generally indicates that the product is produced according to the ASTM standard, and SUS 304 indicates that the product is produced according to the 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, the steel must contain more than 18% chromium and more than 8% nickel by changing the rotating speed of the electromechanical. 304 stainless steel is a brand of stainless steel produced according to American ASTM specification
