Super Duplex Pipe Suppliersis known to have better pressure erosion, splitting obstruction and mechanical properties than some other kind of steel.
Incoloy 800H is a higher carbon version of the alloy 800. The Incoloy 800H Pipe is designed with a superior chemical composition consisting of 30 to 35% of nickel with 19 to 23% of chromium and other constituent alloys.
The Super Duplex 2507 Tube can be used in high-pressure and temperature systems.
Alloy 800H Welded Pipes (also known as WNR 1.4958 Welded Pipe). Chemical and petrochemical processing industries use these UNS N08810 Welded Pipes for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. Power plants use them for super-heater and re-heater tubing.
A Super Duplex 2507 Pipe has outstanding resistance to corrosive and oxidative media.
The Alloy 800H Pipe works well in applications when they are exposed to high temperatures for a prolonged period of time.
The Incoloy 800Ht Pipe is a slight modification to the 800H alloys. In these pipes the combined titanium and aluminum levels allow the pipes to work at slightly higher temperatures than the 800h alloys. Both these alloys can be dual certified and are preferred for use in high-temperature setups.
These tubes have a yield strength between 30 to 60ksi and can be readily elongated by 60-30% in the system.
The Alloy 800H Tube has good machining characteristics as seen in iron-based alloy and they tend to work-harden during the machining process.
These tubes can be readily welded in place following common welding process without requiring a matching filler metal.
A Inconel 800H Seamless Pipe is designed by passing hot steel billets through an extruded metal grade to shape them precisely.
The pipes of seamless configurations have higher load-bearing capacity and strength over other grades.
2507 is a super-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions.
2507 has a higher chromium and molybdenum content which gives the super duplex greater corrosion resistance than other standard duplex grades.
Super Duplex Steel have the benefit as it counterpart ¨C it has lower alloying costs when compared with austenitic grades and ferritic.
Super Duplex is used in gas and oil industry, on offshore platforms, chemical processing equipment pressure vessels and boilers, in heat exchangers.
Duplex is a metal that is made of a two-phase microstructure consisting of austenitic stainless steel and ferritic structures.
Solid solution treatment: fully dissolve various phases in the alloy, strengthen the solid solution, improve toughness and corrosion resistance, eliminate stress and soften, so as to continue processing and forming.
Tempering: The quenched workpiece is heated to an appropriate temperature below the critical point AC1 for a certain period of time, and then cooled by a method that meets the requirements to obtain the required structure and properties.
304 Stainless Steel Plate, is the most popular and economical of the stainless steels.
Chromium, nickel, and iron are the primary alloying elements in austenitic stainless steel.
The alloy has excellent resistance to intergranular corrosion in the as-welded condition.
Highly resistant to corrosion and aesthetically pleasing, stainless steel is used in a wide variety of industries for various applications.
Stainless Steel 304 Sheet is made up of an austenitic stainless steel that has 18% chromium and 8% nickel in the composition.
ASTM A240 is the standard specification for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications.
304 stainless steel plate is comprised of at most 0.08% carbon. 304 stainless steel plate also includes at most 2.0% manganese and 0.75% silicon.
The Stainless Steel 304 Sheet also has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition. The material is strong and has 205MPa minimum yield strength and 515MPa minimum tensile strength in general.
Normalizing: heating steel or steel parts to an appropriate temperature above the critical point AC3 or ACM for a certain period of time and then cooling in air to obtain a heat treatment process of pearlite structure.
Solid solution heat treatment: the alloy is heated to a high temperature single-phase region and maintained at a constant temperature, so that the excess phase is fully dissolved into the solid solution, and then rapidly cooled to obtain a supersaturated solid solution.
Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments
