Steel Material

Stainless steel material (stainless steel) is used in the home industry and the military industry, and also in the nuclear industry. Steel material is divided into five types, namely austenite, ferrite, martensite, duplex and precipitation hardening. Ferritic stainless steel is an attractive alternative in vehicle production because of its corrosion resistance. Different metals have different characteristics from one another, so the welding process of dissimilar metals requires certain techniques. The purpose of this study is to determine the tensile strength of welds in bimetallic welding between low carbon steel plates and stainless-steel plates and to know the hardness of welds in bimetal welding between low carbon steel plates and stainless-steel plates using GTAW welding. The research method used: this research is part of the testing of technical materials conducted by the destructive test method with the category of science and technology development in the field of Mechanical Engineering. There is a trend of increasing tensile strength, yield strength and hardness of bimetallic welding of low carbon steel plates and stainless-steel plates using GTAW welding, that the greater the welding amperes will increase tensile strength, yield strength and hardness. The highest tensile strength was 41.18 Kg / mm2 and the highest yield strength was 41.16 Kgf / mm2 at 60 amperes and the highest hardness was 571.01 BHN at 55 amperes with the corresponding amperage range from the usage table 45 - 65 amperes. In the HAZ area when compared to the parent material, the HAZ area hardness is higher than the parent material and lower than the weld filler.

This paper aims to numerically analyse the ultimate strength of transversely cracked steel plates under longitudinal compressive loading, considering the effect of initial distortion as well. The main objective of this study is to investigate the ultimate compressive strength characteristics of an unstiffened steel plate due to transverse cracking damages located in the middle (i.e. centre cracks and edge cracks). To achieve that, a series of non-linear finite element (FE) analyses are carried out using ANSYS commercial finite element code. The obtained FE results are discussed to indicate the amount of crack influence, in terms of its length and location, on the ultimate compressive strength of a steel plate element with different thicknesses.

Multilayered forged steel plates, which combine the properties of diverse steel qualities, are referred to as Damascus steels. Since the 3rd century AD blades and weapons have been produced by the Damascus technique in Europe. In this work four different steel combinations were investigated. Combining Fe with carbon steel C60 resulted in a ferritic-pearlitic microstructure. By forging two heat-treatable steels C40 and C60 martensite with an inhomogeneous carbon distribution was formed. Combining Fe with an austenitic stainless steel showed ferrite and austenite with grain boundary carbides and segregation bands. The last combination of two cold working steels K110 and K600 led to a complex microstructure with martensite, retained austenite and two special types of carbides. After metallographic preparation and using of different etchants the various microstructures were characterized by light optical microscopy and confirmed by Vicker ́s microhardness measurements. Of high interest are the interfaces and the quality of the weld between the individual steel layers. In some regions oxidation and carbon diffusion were observed.

Abstract. This work studied the feasibility of dissimilar welding between AISI 304 stainless steel and AISI 1020 carbon steel plates with the thickness of 15 mm. The processes applied in this work were gas tungsten arc welding (GTAW) and shield metal arc welding (SMAW). Microstructure of weld metal produced by GTAW consists of delta ferrite network in austenite matrix, while the dendrite of delta ferrite finely distributed in austenite matrix was found in the weld produced by SMAW. Hardness values of weld metals produced using these two techniques were superior to those of stainless steel and carbon steel base metals respectively. Weld metals produced by these two processes were qualified under tension and bending. This was justified by the result that the failed part after transverse tensile test was on carbon steel, and no crack was found in weld metal after U-shape bending. Impact test exhibited higher toughness of weld metal produced by GTAW than that produced by SMAW. This might be from microstructure of the former weld as network of delta ferrite in austenite matrix which might help absorb impact energy. Pitting corrosion potential of weld metal produced by GTAW was higher than that produced by SMAW and stainless steel base metal respectively. In the aspect of mechanical and corrosion properties of the weld, GTAW was considered as a promising process that could be used for dissimilar welding between these two metals.

This paper presents the assessment of the ultimate compressive strength of damaged steel plates with a local dent. The explicit nonlinear finite element code from ABAQUS program was employed to simulate dynamically the dent damage. Therefore, the residual stresses due to the damage were considered in subsequent numerical compression analyses. A parametric study of plates considering residual stresses, geometric imperfections and dents was accomplished. Results showed that local dent is the dominant parameter for the ultimate strength of damaged plates. For a particular dent depth, the effect of welding induced geometric imperfections and residual stresses can be disregarded from the analysis. Afterwards, analytical expressions were developed to estimate the ultimate strength of damaged plates.

Hollow Section

Stainless steel has excellent corrosion resistance properties, considerable long-term durability, and good mechanical strength. Hollow sections are a versatile and efficient form for construction applications. The use of cold-formed stainless steel rectangular hollow section (RHS) and square hollow section (SHS) in construction industry grasps the attention of designers conceiving long-term, cost-effective structures. For cold-formed RHS and SHS, localized imperfection (ω) resulting from rolling and fabrication process is inevitable. ω has inherent variability and has no definitive characterization. In this paper, statistical analysis of the maximum value of ω collected from available experimental data is conducted. A new approach utilizing Fourier series to generate the three-dimensional (3D) models of members with random ω is proposed. Probabilistic studies based on the proposed 3D models are then carried out to evaluate the effect of uncertainty in ω on the ultimate compressive strength of stainless steel columns with cold-formed RHS and SHS. A total of 21 columns that are prone to local buckling reduction are studied. The results show that uncertainty in ω has a considerable influence on the columns with relatively higher cross-sectional slenderness.

Metal Arc Welding

This study examines the effect of heat input on the weld bead profile, microstructure and mechanical properties of single V- joint welded carbon and stainless-steel plates. The as-received sample steel plates were sectioned into eight pieces; dimension 75 X 30 X 10 mm  thicknesses. Shielded metal arc welding (SMAW) of heat inputs 1250 and 2030 J/mm was used to produce full penetration bead on the plates. Although visual inspection indicated that some of the welds were macro defect free, austenitic stainless steel exhibited more weld distortions than the carbon steel and this was partially attributed to its lower carbon content and the width to depth aspect ratio of the weld profile aside the magnitude of the induced stress. For the carbon steel, as the heat input increased, the hardness value of both the heat affected zone and fusion zone increased. In contrast, for stainless steel, the hardness values were reasonably comparable within same weld region (HAZ or FZ) irrespective of heat input. Furthermore, the ultimate tensile strength of the stainless steel decreased as heat input increased while the ductility increased with an increase in heat input, in contrast to carbon steel, where both ductility and ultimate tensile strength generally decreased.
