PRODUCT INTRODUCTION
316 is a brand under American Standard It belongs to stainless steel heat-resisting. corrosion-resisting steel. It is austenitic stainless steel The national standard is 0Cr17Ni12Mo2 It's better than 304 stainless steel In seawater and other media Corrosion resistance is better than 0Cr19Ni9 Mainly pitting corrosion resistant materials.
The appearance difference between 316 stainless steel and 304 stainless steel is as follows:
At present, the two most commonly used stainless steels 304316 (or 1.4308,1.4408 corresponding to German / European standards), the main difference between 316 and 304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more corrosion resistant than 304 in high temperature environment. Therefore, in high temperature environment, engineers generally choose 316 parts.
