Hello, the valve material is 3Gr13, stem 3Gr12, I would like to ask, this valve against sulfur?
Not resistant to sulfur, preferably made of stainless steel.
it is easy to be corroded, the best use of dual phase steel, 20 alloy steel, alloy steel and zirconium C276 wood, but also to see the specific medium containing exactly what, these materials should be the cheapest dual phase steel
3Cr13 martensitic stainless steel, C content is relatively high, if the S is dry, corrosion resistance is relatively small, with 3Cr13 not what big problem, if the water is single, cannot use 3Cr13,
