Q:What are the different chemical resistance grades of special steel?: Special steels, commonly known as stainless steels, possess exceptional resistance to corrosion and chemical attack. They are a category of alloys that contain a substantial amount of chromium, which forms a protective oxide layer on the surface, preventing further corrosion. The chemical resistance of special steel may vary depending on the particular grade or alloy composition. Below are some of the typical chemical resistance grades of special steel: 1. Austenitic Stainless Steel: This is the most prevalent stainless steel type and exhibits excellent resistance to a broad range of chemicals, including organic acids, alkalis, and salts. The most commonly used grade in this category is 304 stainless steel. 2. Ferritic Stainless Steel: Ferritic stainless steels have lower corrosion resistance compared to austenitic grades but still offer good resistance to many chemicals. They are particularly resistant to nitric acid and some organic acids. Grade 430 stainless steel serves as a common example of ferritic stainless steel. 3. Martensitic Stainless Steel: Martensitic stainless steels are recognized for their high strength and hardness. Although they have lower corrosion resistance compared to austenitic and ferritic grades, they can still exhibit good resistance to certain chemicals, especially in mildly corrosive environments. 4.
