316 stainless steel is added with Mo element, Therefore, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, can be used under harsh conditions; excellent work hardening (non-magnetic); excellent high temperature strength; non-magnetic in solid solution state; good gloss of cold rolled products , beautiful.
Uses: equipment used in seawater, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photo, food industry, coastal facilities, ropes, CD rods, bolts, nuts.
The most common difference between the two commonly used stainless steels 304 and 316 is that 316 contains Mo, and it is generally accepted that 316 is more resistant to corrosion and more resistant to corrosion than 304 in high temperature environments. Therefore, in high temperature environments, engineers generally use parts of 316 materials. But the so-called thing is not absolute, in the concentrated sulfuric acid environment, do not use 316 for high temperatures.People who have learned the mechanics have learned the thread. Remember the black solid lubricant that needs to be applied to prevent the thread from smashing at high temperatures: molybdenum disulfide (MoS2). From it, two conclusions were drawn: First, Mo is indeed a high temperature resistant substance, and secondly, Mo easily reacts with high-priced sulfur ions to form sulfides. So no stainless steel is super invincible and corrosion resistant.
The use of 316 stainless steel plates has become more widespread with the development of the economy. People are closely related to stainless steel in daily life, but many people do not know much about the performance of stainless steel, and the maintenance of 316 stainless steel plates is known less. Many people think that stainless steel will never rust. In fact, stainless steel has good corrosion resistance. The reason is that the surface forms a passivation film, which exists in the form of a more stable oxide in nature. That is to say, although the stainless steel is different in oxidation depending on the conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion. All metal surfaces exposed to corrosive environments undergo electrification or chemical reactions and are uniformly corroded.
