Indeed, stainless steel is available in many different grades, which are divided into several family groups based on metallurgical qualities.
Instead of this, 304 and 316 grades are widely used in the different industrial or commercial construction purposes. Infact, there is no difference in the 304 and 316 stainless steel grades both are polished, grained and finished in the exact same way. Further, you can also find more about the 304 Stainless steel joint by visiting http://ecofittingvalve.com( which is alos known as “ข้อต่อสแตนเลส 304 โดยเข้าไปที่ http://ecofittingvalve.com“ in the Thai language).

There is only a material make-up that makes differences between both, although the differences are very slight, they do alter the purpose for which each type of steel can be used.
Moreover, 304 contains 18% chromium and 8% nickel while other 316 – contains 16% chromium, 10% nickel and 2% molybdenum.
Moreover, 304 steel provides good resistance against moderate acidic attack, but is considered inferior when compared to the 316 steel type.
Whereas, 316 is considered to be more heat-resistant and provides superior corrosion resistance, due to the presence of the molybdenum element. 316 is considered to be far more resistant to a number of chemical solutions such as sulphuric acid, bromides and iodides.
No doubt both is made from steel material also a types of steel. Simultaneously, they have their own advantages and have different physical properties as well as their own working principles. For instance, Certainly 306 and 316 is different from each other in every aspect.
