Hardness of Ductile Cast Iron – ASTM A536 – 60-40-18. Brinell hardness of ductile cast Iron – ASTM A536 – 60-40-18 is approximately 150 – 180 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching.
The present study was developed surrounding the heat treatability of welded joints made with a high strength ductile cast iron detaining an ultimate tensile strength of 700 MPa, and aims to determine which heat treatment procedures promote the best results, in terms of microstructure and mechanical properties.
27 sie 2024 · Dissimilar welded joints of ductile cast iron and stainless steel 304 were produced under various welding conditions using shielded metal arc welding process (SMAW) and tungsten inert gas...
The present work analyses the strength and microstuctural variations of ductile cast iron welded by means of the TIG technique, without heat treatment and using different filler materials (pearlitic malleable cast iron, Fe-Ni alloy and bronze and manganese alloy).
Material types. Cast irons can be conveniently grouped according to their structure which influences their mechanical properties and weldability; the main groups of general engineering cast irons are shown in Fig. 1. Fig.1. Main groups of engineering cast irons. Grey cast irons contain 2.0 - 4.5% carbon and 1 - 3% silicon.
This paper analyzes the corrosion resistance and the mechanical and microstructural properties of a welded joint of ductile cast iron using AISI316L stainless steel as filler material and three different heat treatments: preheating at 250 and 450 ºC and a post-weld annealing treatment.
1 gru 2022 · Current work presents a review of various filler materials (electrodes) used to weld ductile cast iron using two common industrial welding processes, namely, shielded metal arc welding...
