  • General PropertiesCorrosion ResistanceMechanical PropertiesAlloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100). It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 1500°F (427 816°C). The alloy has good oxidation resistance and creep strength to 1500°F (816°C). It also possesses good low temperature toughness. People also askWhat is 347h stainless steel?What is 347h stainless steel?Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification.Alloy 347/347H Heat Resistant Stainless Steel Plate - Sandmeyer Steel

    Jun 05, 2010 · As regarding PWHT of SS TP 347H furnace tubes after welding and fabrication, NACE RP-170,-Protection of Austenitic S.S against Polythionic Acid Corrosion during Refinery Shutdowns- recommneds stabilizing anneal at the above temperature for typically 2-4 hrs. (1050?F). Tube materials were specified as Type 347H SS stainless steel in order to PWHT for SS321 Material - CR4 Discussion ThreadApr 16, 2014 · Carbon steel tools, also supports or even sparks from grinding carbon steel, can embed fragments into the surface of the stainless steel. These fragments can then rust if moistened. Therefore it is recommended that stainless steel fabrication be carried out in a separate designated area and special stainless steel tools used where possible.

    Stabilization Heat Treatment of Austenitic Stainless Steel

    Apr 15, 2007 · Typically the first line of protection is to use an L grade (low carbon) stainless steel and/or filler metal (e.g., Types 304L or 316L stainless steel). Lower carbon, means fewer carbides to deplete the chromium. However, with enough heat or time sensitization can still occur in the L grades. Stainless Steel Grade 347H (UNS S34709)Grade 347H stainless steel can be readily stamped, blanked, spun and drawn as it is quite tough and ductile. Annealing. Grade 347H stainless steel can be annealed at temperature ranging from 1010 to 1193°C (1850 to 2000°F) and then quenched with water. Hardening. Grade 347H stainless steel is unresponsive to heat treatment. Stainless Steel 347H Flanges, SS 347H Pipe Flanges, UNS Supplier and Manufacturer of Stainless Steel 347H Flanges.

    martensitic stainless steels. Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld. 3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn, up to 0.40% C and small amounts of a few other elements such as Mo, Ti, Nb (Cb) and Ta. The balance between the Cr and Ni Stainless steel, Nitronic 60 stainless steel, Nitronic 50 316 is the next most common austenitic stainless steel, and 316L is the low-carbon variation. These have better resistance to specific types of corrosion. 316 is often used to build nuclear plants, while 316L is beneficial for the chemical and pharmaceutical industries.

    Dec 27, 2003 · Hi Ali Generally you do not need to perform any post weld heat treatment, (PWHT) because the Nb added to the base metal and filler will tend to stabilize the weld and HAZ. As with all Austenitic alloys, you just need to weld it relatively cold, with a relatively low heat input. Generally the H grades are used where high temperature strength properties are required. welding of S.S 347H and Heat treatmentDec 27, 2003 · Hi Ali Generally you do not need to perform any post weld heat treatment, (PWHT) because the Nb added to the base metal and filler will tend to stabilize the weld and HAZ.

Stainless steel and PWHT Post weld heat treatment Nov 03, 2019 · Most austenitic stainless steel weldments do not require post-weld heat treatment. For those that do, the heat treatment temperature should reflect the particular concern that is being addressed. The necessity for any type of heat treatment of austenitic chromium-nickel steel weldments depends largely on the service conditions encountered. For some applications, heat treatment is used
