This alloy has the following characteristics:
Duplex stainless steel 2507 alloy is a duplex stainless steel composed of 25% chromium, 4% molybdenum, and 7% nickel and nitrogen alloys. It has high strength, good impact toughness, and good overall and local resistance to stress corrosion. The content of chromium, molybdenum and nitrogen in the dual phase steel 2507 makes it resistant to pitting and crevice corrosion in oxidizing and acidic solutions. The dual-phase microstructure of stainless steel helps to improve its resistance to stress corrosion cracking. Under certain temperature, stress, oxygen and chloride, chloride stress corrosion will occur in austenitic stainless steel. Due to its higher alloy content, the corrosion resistance and strength of 2507 are due to 2205.
2507 applications are:
1. For the manufacture of pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry)
2.Used to manufacture petroleum natural gas pipelines and heat exchanger pipes
3. Sewage treatment system
4. Pulp and paper industry classifiers, bleaching equipment, storage and processing systems
5.Rotary shafts, press rolls, blades, impellers, etc. in a high-strength, corrosion-resistant environment
6. Cargo boxes for ships and trucks
7. Food processing equipment
8. Energy industry FGD system, industrial scrubbing system, absorption tower
