20 steel (screw) hydrogen-induced cracking fracture and stress corrosion fracture
Abstract
Hydrogen-induced cracking (HIC) is a corrosion mechanism that affects many metallic materials, including steel. It is a type of hydrogen embrittlement that causes the steel to become brittle and susceptible to cracking. In the present study, the effect of hydrogen on steel screws was eval......
20 steel (annealing treatment) low carbon carbon steel metallographic structure
，
Abstract
The purpose of this study was to analyze the microstructure of low carbon carbon steel 20-steel (annealed) through metallography. Samples of the three different states, namely as delivered, annealed, and polished, were cut from soldering part of C-type steel washer. It was found that t......
Morphology of α-MnS on Columnar Grain Fracture of 25 Steel
The morphology of alpha-MnS on a Fractured Steel-Column Crystal
Manganese sulfide, commonly known as alpha-MnS, is an important mineral found in many geological environments. It has been studied extensively in metamorphic and sedimentary ores and is often used as a source of manganese. In the pre......
Fracture Analysis of 2Cr13 Steel (Quenched and Tempered State, Impact Test)
Metallographic analysis of the breakage of AISI 420 Stainless Steel
Introduction
Stainless steel is a type of steel with a corrosion-resistant alloy composed of iron and chromium. Many grades of stainless steel are available, and the grade selected depends on the specific application. Because of......
