Who is the nobleman in the stainless steel ball?

316 and 440 belong to the aristocracy of stainless steel balls, with good rust resistance and strong corrosion resistance, and the price increases with the price. The following Condar Steel Ball introduces the two in detail:

1.316 stainless steel ballsAfter 304, it is the second most widely used steel grade. It is mainly used in food industry and surgical equipment. The addition of molybdenum makes it a special corrosion-resistant structure. Because it has better resistance to chloride corrosion than 304, it is also used as “ship steel”. SS316 is usually used in nuclear fuel recovery devices, medical equipment, diving equipment, etc.

2.440 stainless steel ballsHigh-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, higher yield strength can be obtained. The hardness can reach 58HRC, which is among the hardest stainless steels. Combining the advantages of stainless steel and bearing steel, it is called special steel. The most common application example is “razor blades”. There are three commonly used models: 440A, 440B, 440C, and 440F (easy processing type).
