316/316L Stainless Steel AK Steel

316/316L STAINLESS STEEL TYPE 316 is widely used in applications requiring corrosion resistance superior to Type 304, or good elevated temperature strength. Typical uses include exhaust manifolds, furnace parts, heat exchangers,

317L Stainless Steel, UNS S31703, Stainless Steel 317L

Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion. Resistance increases with molybdenum alloy content. 317L is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C). At temperatures under 100°F (38°C) this alloy has excellent resistance to solutions of higher Behavior of Steels against Corrosion in Peroxide Solutionssteel 304L, 316L, 2205 and mild steel (MS) in peroxide solutions of pH 10. The materials were tested for uniform corrosion, pitting and crevice corrosion and attack around the weld area. Corrosion attack estimated from long term immersion tests is found in agreement, by and large, with that analysed from electrochemical test.

Changes in the microstructure of a weld can change its behavior [13]. This article evaluates the weldability and micro-structural effects of ionizing radiation on AISI 304 stainless steel welded with a tungsten electrode and AISI 316L stainless steel ller material. Characterization of weldability, microstructure, and Oct 26, 2015 · Fe, Ni and Cr are distributed uniformly in WM as well as 316L stainless steel, but Fe is relatively scarce in the M 3 B 2 phase. The interface between WM and 316L stainless steel seems bland due to the similar chemical composition of 316L stainless steel and the -Fe based binder, thus its discussion is concise in this paper.

    Corrosion Behavior of Welded Stainless Steel

    ABSTRACT. The corrosion resistance of stainless steels depends on a protective, passive film being fornled at the steel sur- face on exposure to the service environ- ment. The use of fusion welding for fab- rication leads to local compositional variations within the material, which may significantly alter the stability of the passive layer and hence the corrosion be- havior. The paper reviews published Corrosion behavior of stainless steel weldments in Jan 03, 2018 · In this study corrosion behavior of TIG welded 316L stainless steel plates in simulated biological solutions is investigated. The mechanical testing results showed slight decrease in ductility after welding and the fracture surface represented mixed cleavage and inclusions containing dimple structure. The heat affected and weld zone (WZ) demonstrated higher corrosion potential and

    Corrosion of an austenite and ferrite stainless steel weld

    order to define the corrosion behavior of all the investigated materials. A three-compartment glass cell was used. Surface area (A) of the working electrodes of pure austenite and ferrite stainless steel was 2 cm2. Working electrodes of welded stainless steels near the weld (A = EFFECT OF TEMPERATURE RATIO (TS/TM) AND TIME ON 316L stainless steel powder is used since its good overall mechanical properties, especially good strength at evaluated temperature and superior corrosion resistance behavior, are suitable for a wide range of application. 316L type is an austenitic chromium-nickel stainless steel containing a small amount of molybdenum.

    Effect of Oxidation on Corrosion Behavior of Austenitic

    The in-cell stainless steel piping and erection works require extensive welding. In many instances the approach for gas tungsten arc welding (GTAW) is limited and it is not possible to provide a cover of high purity inert Argon gas (backing shield) and in some instances, oxidation of the weldment takes place. The oxide forms over the weld fusion zone (root pass) as well as a heat tint forms Effect of Phase Transformation on Stress Corrosion The present study aims to evaluate the stress corrosion behavior of additively manufactured austenitic stainless steel produced by the wire arc additive manufacturing (WAAM) process. This was examined in comparison with its counterpart, wrought alloy, by electrochemical analysis in terms of potentiodynamic polarization and impedance spectroscopy and by slow strain rate testing (SSRT) in a

    Heat Treatment of SS 316L for Automotive Applications

    Stainless steel 316L (SS 316L) is a low carbon-chromium-nickel-molybdenum austenitic stainless steel. Its application in automotive industry include as exhaust housings for catalytic converters and turbocharger. In this research, the tempering heat treatment was conducted by using SS 316L samples. These steels were austenitized at 860°C for 1 hours before doing two tempering process. Influence of heat treatment on corrosion resistance of Aug 21, 2019 · At present, many scholars have studied the influence of heat treatment on the microstructure and mechanical properties of explosive welding stainless steel clad steel plate [1015]. However, the influence of heat treatment on the corrosion resistance of explosive welding 316L stainless steel composite plate is less studied.

    Resistance to Corrosion - 316 316L - Stainless Steel Tube

    316 1.4401 / 316L 1.4404 Resistance to Corrosion. Alloys 316, 316L, and 317L are more resistant to atmospheric and other mild types of corrosion than the 18-8 stainless steel.In general, media that do not corrode 18-8 stainless steel tube will not attack these molybdenum-containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum-bearing Welding of Austenitic Stainless Steel - Part 2 - TWIWelding consumables must also be selected with low carbon content if best corrosion resistance is required. Most arc welding consumables contain less than 0.03% carbon but there are filler metals available with carbon contents of up to 0.10%; these should only be used to weld the 'H' grades of steel where good creep resistance is required.

    Effect of TIG welding on corrosion behavior of 316L

    May 01, 2007 · The corrosion behavior of the welded and heat treated 316L SS (E corr = 140 mV, i corr = 365 nA) was better than the as-welded 316L SS (E corr = 206 mV, i corr = 570 nA) up to 50 mV, as manifested by a shift of the polarization curve of the welded and heat treated sample to the left upper of the curve of the as-welded sample.
