CN105842308A - Method for eliminating super 304H steel The invention discloses a method for eliminating super 304H steel inter-granular corrosion sensitivity, which includes the following steps:(1) preparation of a solid solution sample:performing homogenization solid solution treatment to a super 304H steel pipe to obtain the solid solution sample having homogeneous tissue, and cutting a flat sheet sample, and grinding the surface of the sample Effect of filler addition on solidification behaviour and Super 304H austenitic stainless steel tubes of outer diameter 57.1 mm and wall thickness of 3.5 mm were used in this investigation. Chemical composition of the Super 304H tube and filler metal used in this investiga-tion are presented in Table 1. The tensile properties of

Hot corrosion behaviors of Super 304H austenitic stainless

Oct 19, 2018 · Among advanced materials which have been developed and applied for high-temperature and high-pressure USC components, Super 304H austenitic stainless steel with high strength and high corrosion resistance has been used to fabricate superheated and reheated tubes of Investigating the effect of Cu-rich phase on the corrosion Jan 01, 2018 · 1. Introduction. Super 304H stainless steel (Super 304H SS), newly developed by the addition of alloying elements Cu, Nb and N on the basis of 18Cr-8Ni stainless steel , , , , is being widely used in ultra-super critical fossil boilers because of its superior high temperature strength , oxidation resistance and steam corrosion resistance .The mechanical properties of Super 304H SS have been MECHANICAL PROPERTIES AND MICROSTRUCTURE SUPER 304H austenitic stainless steel is used for boiler plant heat exchanger tubes to increase the efficiency that contain minimum of 17-19% chromium and 7.5-10.5% nickel. SUPER 304 stainless steel is used in chemical, petrochemical and fertilizer industries and as equipment in dairy, food processing, cryogenic vessels and as heat exchanger

Microstructure and Corrosion Resistant Property Research

Microstructure of Super 304H and TP347H austenitic heat resistance steel welding joint by handwork argon tungsten-arc welding and electro-chemical corrosion property of weld metal and two base materials were investigated by SEM and M273 constant potential rectifier. Most Widely Used Austenitic Stainless Steel Modified Alloy 304/304H (UNS S30400/ S30409) is a modification of the most widely utilized 18-8 chromium-nickel austenitic stainless steel. The carbon content is controlled in the range of 0.04 0.10% for increased strength at temperatures above 800°F (427°C).

Paper:Effect of aging process on steam oxidation

Jun 01, 2021 · The analyses indicated that Super 304H steel was in a fine grain structure (ASTM 78), whereas HR3C showed a coarse grain structure (ASTM 34) . For better traceability the samples received unique codes:S for Super 304H steel, H for HR3C steel. The Properties, structure and creep resistance of austenitic The Super 304H steel structure is tested for a new material and for the superheater material after 100,000 h of operation. Stainless Steel Tubing,NickelAlloy,Ti& Copper Alloy Tubing Austenitic steel Super 304H used for ultra-Supercritical boiler has been developed for ultra-Supercritical boiler tube application, its inoxidibility at 650 is better than common 18/28 stainless steel such as SA213 TP304H,SA213 TP347H and at the samec condition. it s depth of oxide etch is half of SA213 TP304H,67 % of SA213 TP347H.

The Changes in Mechanical Properties of Austenitic Creep

The paper presents the results of the analysis of secondary phases formed during thermal exposure in creep resistant austenitic steels of SUPER 304H and HR3C types. These steels were worldwide used for construction of the superheaters (the heat exchangers) of supercritical and ultra-supercritical (USC) coal-fired power plants.Alloy 304/304H Austenitic Stainless Steel Plate Alloy 304/304H (UNS S30400/ S30409) is a modification of the most widely utilized "18-8" chromium-nickel austenitic stainless steel. The carbon content is controlled in the range of 0.04-0.10% for increased strength at temperatures above 800°F (427°C).
