The material of stainless steel flange

　　The material of stainless steel flange is according to the different models and different use, chemical composition and production. Stainless steel can be use, chemical composition and microstructure to general classification.

　　By chemical composition: 1, the CR series: series of ferrite, column 2, CR - NI series markov system: system of austenite, abnormal series, series of precipitation hardening.

　　Second, in the classification of the microstructure: 1, austenitic stainless steel 2,  ferritic stainless steel 3, martensite stainless steel 4,  precipitation hardening stainless steel 5,duplex stainless steel

　　Third, there are several models:

　　1, good ductility, model 301 - used for forming products, also can rapid hardening by mechanical processing, good weldability, abrasion resistance and fatigue strength is better than that of 304 stainless steel.

　　2, model 302-304, corrosion resistance due to the carbon intensity of relatively high and better.

　　3, model 303 - by adding a small amount of sulfur and phosphorus from 304 are more likely to machining.

　　4, model 304 - gm model; The 18/8 stainless steel. GB brand of 0 cr18ni9.

　　5, model 309 - compared with 304 has better temperature resistance.

　　We are specialized in producing flanges, Such as weld neck flanges, Slip on flanges, Blind flanges, Socket flanges, threaded flanges and plate flanges etc. We have ability to produce you the detailed drawing flanges also. We have been in this line for over 25 years. Our products are exported to many countries and regions, such as Southeast Asia, the Middle East, Europe and America etc. We have a good reputation in domestic and foreign markets.
