AISI 1045 Medium Carbon Steel - AZoM

  • MachiningWeldingHeat TreatmentApplicationsWelding of Stainless Steels - Total MateriaStainless steels can be welded using several different procedures such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. These steels are slightly more difficult to weld than mild carbon steels. The physical properties of stainless steel are different from mild steel and this makes it weld differently.

Austenitic Grain-Size of Steel MetallurgyAustenitic grain-size or just the grain-size of steel means, the grain-size of austenite that existed prior to its transformation to ferrite and carbide mixture or martensite, that is, the size of prior austenite-grains (that existed at a higher temperature) before the steel is cooled, and before the austenite is transformed to other structural

    Corrosion and Corrosion Properties of Stainless Steels

    If the precipitates at the grain boundaries have higher electrode potential the grains will dissolve (anodic reaction). In this case the grain boundaries will not be attacked. Figure 1 shows the intergranular corrosion. Figure 1:Intergranular corrosion. Stainless steel has a Defects / Imperfections in Welds - Reheat Cracking - TWI

    • CausesBest Practice in PreventionSteel ChoiceWelding Procedure and TechniqueThe principal cause is that when heat treating susceptible steels, the grain interior becomes strengthened by carbide precipitation, forcing the relaxation of residual stresses by creep deformation at the grain boundaries. The presence of impurities which segregate to the grain boundaries and promote temper embrittlement, e.g. antimony, arsenic, tin, sulphur and phosphorus, will increase the susceptibility to reheat cracking. The joint design can increase the risk of cracking. For example, joints likely to contain Flash-Butt Welding of High Strength Steels - Nippon Steelelements, but also the ductility of the weld, are related to crack susceptibility. A study was conducted on those effects using steel sheets 2.4 mm to 3.2 mm in thickness and 323 MPa to 691 MPa in tensile strength (see Table 1, Gr. D). The test specimens used were Si-Mn-based mild steel sheets and high-strength steel sheets,

      EFFECTS OF POST WELD HEAT TREATMENT ON

      Keywords:post weld heat treatment, brinell hardness, carbon steel and SMAW. INTRODUCTION Post Weld Heat Treatment (PWHT), or stress relief as it is sometimes known, is a method for reducing and redistributing the residual stresses in the material that have been introduced by welding. The extent of Effect of Autogenous Arc Welding Processes on Fatigue Fusion welding of ferritic stain-less steel is associated with many problems. Coarsening of grain is an important problem in ferritic stainless steel weldment and such grain coarsening results in lower tough-ness.1) During welding of ferritic stainless steels, chromium car-

      Basic coated electrodes are recommended for manual welding. These fine-grain structural steel grades are not suitable for heat treatment above 580 °C. Stress relief annealing (530 - 580 °C) is required only if called for in the regulations or if manufacturing conditions make a reduction of the residual welding stresses appear useful. Heat Affected Zone - an overview ScienceDirect TopicsNorman Bailey BMet. CEng. FIM. FWeldI, in Weldability of Ferritic Steels, 1994. The heat-affected zone Description. The HAZ is the crucial area in welding because, once the steel has been selected, the HAZ and its properties have to be accepted, whereas a weld metal can be changed if necessary.

Therefore, when welding steel which is thicker than 25 mm, or when the C and Mn contents are higher than 0.3 % and 1.4 % respectively, then proper precaution and the use of low H2 electrodes or fluxes is needed to prevent H2 cracking.

Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher. Stainless steels which require special welding procedures are discussed in later sections

Good quality joints were obtained using a pulsed Nd:YAG laser for the following process parameters:energy of 1.75 J, welding speed of 525 mm/min and pulse duration of 4 ms. The Influence of Austenite Grain Size during Welding Abstract:Non-isothermal austenite grain growth kinetics under the influence of several combinations of Nb, Ti and Mo containing complex precipitates has been studied in a microalloyed linepipe steel. The goal of these studies is the development of a grain growth model to predict the austenite grain size in the weld heat affected zone (HAZ).
