Alloy 2507 Super Duplex Tubing

2507 Super Duplex is a high alloy duplex stainless steel with a PRE (pitting resistance equivalent) value of 42.5 minimum. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength. It is particularly suited for use in aggressive environments such as warm chlorinated seawater and acidic chloride-containing media. It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing. The grade is also suitable for hydraulic and instrumentation applications in tropical marine environments.

GRADES:

Grade 304 is the most commonly used, it is used for a variety of household and industrial applications such as bench tops, food handling and processing equipment.
Grade 316 is the second most commonly used, usually regarded as the standard “marine grade” but not fully resistant to sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining.
Grade 430 (magnetic), it is not actually magnetic itself, it means magnets will stick to it.
