High Temperature Alloy
◆Alloy20cb-3 has excellent resistance to stress corrosion cracking and good resistance to local reducing compound medium corrosion, and is used in sulfuric acid environment and industrial installations of sulfuric acid solution containing halogen ions and metal ions.
◆Alloy28 is widely used in papermaking, pharmaceutical, chemical, environmental protection, shipbuilding and other industries.
◆Alloy31 (N08031/1.4562) is a nitrogen-containing iron-nickel-molybdenum alloy whose performance is between super austenitic stainless steel and existing nickel-based alloys. It is suitable for chemical and petrochemical, environmental engineering and oil and gas production, etc. industrial field.
◆Alloy33 is a kind of metal material that works for a long time under the high temperature of 600-1200 ℃ and certain stress. It has high high temperature strength, good anti-oxidation and anti-corrosion performance.
◆Alloy75 has good tissue stability and service reliability under high temperature conditions, and is suitable for aerospace, aviation, petroleum, chemical industry, and an important material for ships
