Microstructure Characterization of SUS444 Ferritic Stainless Steel
… exhaust manifolds with thinner heat resistant stainless steel one is a prime example of this approach. Material for a thin exhaust manifold must tolerate cyclic thermal fatigue. In SUS 444, this characteristic is directly related to the influence of microstructure on high temperature strength …

Precipitation and fracture in a ferritic stainless steel
A dual stabilised ferritic stainless steel with titanium and niobium additions had been experiencing failures during production. Following hot rolling and cooling while coiled and prior to annealing, the steel had been prone to shattering across its width during uncoiling. This project was …

Microstructure and texture development in AISI430 ferritic stainless steel
AISI 430 ferritic stainless steel (FSS) is the most widely used FSS alloy due to good resistance to stress corrosion cracking. Owing to the chemical composition range, AISI 430 alloys undergo a partial phase transformation of ferrite to austenite when subjected to hot rolling temperatures. …

Effects of cold metal transfer welding on properties of ferritic stainless steel
Stainless steels are a classification of materials that have been available for over 100 years and over that time manufacturers have created variations on chemical composition and manufacturing route, to create materials that meet specific criteria set by the consumer. One type of stainless steel, …

Evaluation of the sag properties in a dual stabilized ferritic stainless steel
The dual stabilised type 441 (DIN 1.4509) ferritic stainless steel is primarily used in the automative industry for catalytic converters. The steel, in addition to oxidation and corrosion resistance, is required to have a certain degree of creep resistance in the operating environment. The …

The influence of microstructure on the creep properties of 441 ferritic stainless steel
… of microstructure on the creep properties of 441 stainless steel. Of particular interest was the effect of grain size and of the niobium content. A further requirement of this investigation was to design and manufacture two lever-arm type, constant load creep rigs in response to the need for a …

Influence of composition and thermomechanical processing on microstructure evolution in AISI 430 ferritic stainless steel(FSS)
… on the evolution of microstructure in the ferritic stainless steel grade AISI 430. In particular, it focuses on the influence of these variables on the hot band annealing behaviour of this steel. The material employed was obtained from laboratory and commercial heats. Two hot roll finish …

Effect of hot working characteristics on the texture development in AISI 430 and 433 ferritic stainless steel
The last seven hot rolling passes of the ferritic stainless steels (FSS) AISI 430 and AISI 433 (the latter an Al-added variant of 430) were simulated on Gleeble-1500D® and Gleeble-3800TM® thermo-mechanical simulators to investigate the effect of temperature, strain rate and inter-pass time on the …

The effect of the cast structure on the evolution of texture during processing of AISI 433 ferritic stainless steel
Ferritic stainless steels (FSSs) are gaining popularity because they are cheaper than austenitic stainless steels (ASS) since they contain almost no nickel. Amongst these FSSs, there is a relatively new grade of steel designated AISI 433 i.e. 430 with added Aluminium (Al) and is produced by …

Design of bio-inspired texturing treatments, via high power ultra-short pulse lasers, of ferritic stainless steel surfaces that inhibit the formation of bacterial biofouling on tools for hospital use and in the food industry
… The material chosen for this study is EN 1.4016 ferritic stainless steel with bright finish, as it is widely used in both the food industry and healthcare environments, as well as in other applications like door handles and handrails, which are in frequent contact with human hands and therefore …

Influence of grain size and niobium content on the creep resistance of ferritic stainless steels
Type 441 ferritic stainless steel is used for the production of catalytic converter housings. As the housing is subjected to high temperatures it is necessary that the material offers creep resistance. Type 441 is dual stabilised with Ti and Nb to provide improved weldability; however, Nb addition …

Materials Development for the Fabrication of Metal-Supported Solid Oxide Fuel Cells by Co-sintering
… YSZ (Y2O3 stabilized ZrO2), Ni-YSZ cermet, and ferritic stainless steel are considered for the electrolyte, anode and the support respectively. The anode and electrolyte were modified with the help of suitable dopants and the multilayer design was also altered in order to facilitate the …
