Stainless steel ball valve selection:

In the production of stainless steel ball valve body material grade 201,304,316,316 L and so on. The correct choice of their own engineering suitable stainless steel ball valve, according to each material grade of stainless steel ball valve to do the following explanation:

First, 201 material stainless steel ball valve is a rarely used body material, because he than cast steel ball valve advantages are not so fast corrosion under wet engineering. Generally, it is not recommended to buy.

Second, 304 (0Cr18Ni9) as a kind of widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other thermal processing good, no heat treatment hardening phenomenon (no magnetic, then use temperature conspiracy -196℃ ~ 800℃). And suitable for alkaline medium engineering use.

Third, 316 (0Cr17Ni12Mo2) due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in caustic conditions; Chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; Photography, pharmaceutical industry, coastal facilities. A combination of factors can be concluded that 316 stainless steel ball valve is suitable for acid medium engineering use.

Fourth, 316L (00Cr17Ni14Mo2) stainless steel ball valve body is mainly made of stainless steel corrosion resistance performance is relatively high, high temperature strength, the cost is relatively high. Generally in the food industry, fine chemical industry, precision clock industry and other industries.
