Product Description

Product Description

 

Introduction

LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
 

Stainless steel Super Duplex 2507 is designed to handle highly corrosive conditions and situations were high strength is required. High molybdenum, chromium and nitrogen content in Super Duplex 2507 help the material withstand pitting and crevice corrosion. The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.

Duplex Stainless 2507 Applications

 

▪ Oil and gas industry equipment
▪ Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems
▪ Chemical process industries, heat exchangers, vessels, and piping
▪ Desalination plants, high pressure RO-plant and seawater piping
▪ Mechanical and structural components, high strength, corrosion-resistant parts
▪ Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping

Welding

 

2507 possesses good weldability and can be joined to itself or other materials by shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), plasma arc welding (PAW), flux cored wire (FCW), or submerged arc welding (SAW). 2507/P100 filler metal is suggested when welding 2507 because it will produce the appropriate duplex weld structure.

Preheating of 2507 is not necessary except to prevent condensation on cold metal. The interpass weld temperature should not exceed 300°F or the weld integrity can be adversely affected. The root should be shielded with argon or 90% N2/10% H2 purging gas for maximum corrosion resistance. The latter provides better corrosion resistance.
