Alloy DIN W.NR.1.4547 Stainless Pipes ASME A 312,A 999 Welded Tubes

1 Alloy DIN W.NR.1.4547:

FEATURES

S31254 is a high performance austenitic stainless steel.Its high alloying elements content imparts excellent resistance to uniform.pitting and crevice corrosion,and stress corrosion cracking.It was originally developed to withstand the corrosion of acids,especially in the presence of halide ions,such as hydrochloric acid, hydrofluoric acid,phosphoric acid,and sulphuric acid contaminated with chlorides.In certain environments it is an alternative to more expensive Alloy alloys and titanium alloys.

APPLICATIONS

Chemical processing equipment,pulp and paper industry bleaching equipment,desalination plant seawater piping,food and beverage industry,pharmaceuticals,and hydrometallurgy.

2 TOBO GROUP deal with stainless steel seamless pipe and tube already more than 10 years, every year sell more than 80000 tons of stainless steel seamless pipe and tube. Our client already cover more than 45 countries.

BENEFITS of 6% MOLY

• High resistance to pitting, crevice and general corrosion.
• Very high resistance to chloride stress corrosion cracking.
• 50% stronger than 300-series austenitic stainless steels.
• Excellent impact toughness.
• Excellent workability and weld ability.

6% MOLY APPLICATIONS

• Seawater handling equipment; heat exchanger, cooling water pipes
• Pulp mill bleach systems; drums, vats and press rolls.
• Tall oil distillation columns and equipment
• Chemical processing equipment
• Food processing equipment
• Desalination equipment
• Flue gas desulphurization scrubbers
• Oil and gas production equipment
• Tanks and pipelines for various chemicals with high halide levels
• UNS S31254,UNS S32760, UNS S31803, UNS S32750

• chemical process, petrochemical and offshore platforms and seawater equipment.

  Other uses of S32750 include heat exchangers, pressure vessels and boilers, fire-fighting systems, desalination plants, high pressure RO-plant and seawater piping, absorber towers, ducting & piping and power industry FGD systems.

  UNS S32750 also contains excellent mechanical properties, meaning that a light gauge of S32750 can be used to achieve the same design strength of a thicker nickel alloy – saving both weight and overall cost of fabrication.

• UNS S31803 is a Duplex stainless steel equivalent to A182 F51 (1.4462) created as a austenitic ferretic iron chromium-nickel alloy with molybdenum addition.

  Designed to combine improved resistance to stress corrosion cracking, pitting and crevice corrosion, S31803 is roughly double the strength of standard austenitic stainless steel. This means that UNS S31803 can be used successfully as an alternative to standard stainless steel specifications where a higher strength and higher stress corrosion resistance is required.

  As Duplex material, UNS S31803 offers the benefits of high strength and corrosion resistance as well as low thermal expansion, higher heat conductivity than austenitic steels, high energy absorption and good workability and weld ability.

  Uses of UNS S31803 include forged or rolled alloy steel pipe flanges, primarily for the petrochemical industry, forged fittings and valves for high temperature application, heat exchangers, chemical tanks, refineries, compressor parts for seawater desalination plants and offshore press ure vessel parts.
