I. 304stainless bearings


304stainless bearings using universal stainless steel ball, its role is more extensive, food equipment, general chemical equipment, atomic energy industry equipment, etc., corrosion resistance and molding performance is particularly good.


Second, 316stainless bearings

316stainless bearings is a hollow long round wire, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial conveying pipelines and mechanical structural components, etc.. In addition, in the bending, torsional strength of the same, lighter weight, so also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for the production of a variety of conventional weapons, gun barrels, shells, etc.

Third, the difference between 304 stainless steel and 316stainless bearings


In fact, the general public with the naked eye simply can not see the difference between 304 and 316 stainless steel, generally need professional inspection. The market will also have some 316 stainless steel containing Mo, better than 304 stainless steel corrosion resistance in high-temperature environments, so in high-temperature environments, engineers will generally choose 316 material parts.

3.1, 304stainless bearings and 316stainless bearings advantages of the difference.


304stainless bearings processing performance is good, high toughness, wear resistance, low temperature resistance; thermal expansion performance and insulation performance is excellent.


316stainless bearings corrosion resistance, atmospheric corrosion resistance and high temperature strength and anti-magnetic.

In addition, 316 is mainly to reduce the Cr content to improve the Ni content and increase the Mo2% ~ 3%. Thus, its corrosion resistance is stronger than 304, suitable for use in the chemical industry, seawater and other environments, likewise, 316 cost is higher than 304, generally 316 used in places with higher requirements, to replace 304.

In general, 304stainless bearings and 316stainless bearings in the chemical corrosion resistance of the two differences are not significant, but in some specific media differences. In specific cases, this material is more sensitive to pitting corrosion. To reduce these sensitivities an additional 2-3% molybdenum is added, giving rise to 316 stainless steel. And these additional molybdenum can also reduce the corrosion of certain hot organic acids.

Therefore, 316stainless bearings corrosion resistance is better than 304 stainless steel, pulp and paper production process has good corrosion resistance. And 316 stainless steel is also resistant to marine and aggressive industrial atmospheres.
