Stainless Steel 316 Valves are special as they have unique design features. You can check out some of the features here-
The solutions which have 1- 5% of concentration are dilute solutions and these valves are resistant to them. Generally, the solutions of sulfuric acid come under this category. Oxidizing acids too come in this category but some are eliminated as they are not acidic as their other counterparts.
It is vulnerable to corrosion between the granules and is prone to carbide falls or precipitation in the range of 427-degree C to 816-degree C which if converted presents the figure of 800-degree F to 1500-degree F.
You can restore the property of resistance to corrosion by the process of annealing carried out after welding.
They are used generally where the excess of pressure has to be handled and frequent carbide attacks occur.
Due to its structural strength, it finds employment in heavy duty sectors where jobs requiring high tensile strength are car
