Strip Thickness Measurement
Sheet Metal Thickness Measurement
Sheet metal is a common material in industrial production, widely used in integrated circuit boards, waterproof layers, insulation layers, automotive interiors, and many other places. However, when these parts are manufactured, it is essential to ensure the thick......
First piece (batch) sample inspection
In order to ensure the quality of the first batch of samples, the official laboratory conduct test to examine the samples.
First, the sample size and the number of batches should be determined. For this purpose, an appropriate sample size gauge can be set up for each batch sample. Then, the Analy......

油岩组学
Sedimentary rocks are composed of lithified depositional environments and associated sediments. They form the most important rock type for both scientific research and commercial application. In the oil and gas industry, sedimentary rocks form an integral part of geology studies and hydr......
45 steel (normalized) low-magnification structure and non-metallic inclusions
INTRODUCTION
45 steel is a variation of steel alloy that is designed to meet the special requirements of various technological applications. It is also known as 45BR, 45 Steel (L-fold), 45 Polymer Steel (AISI 45) and 45 High Strength Steel. The 45 steel alloy is composed of an iron base with a mol......
(Mn, Fe)S Inclusions in 5CrNiMo Steel
Abstract
Manganese and Iron-based sulfide inclusions (Mn-Fe-S) are major contributors to the many mechanical properties of 5CrNiMo steel. In this paper, the formation, occurrence, and microstructure of Mn-Fe-S inclusions were studied. It was found that Mn-Fe-S inclusions form mainly due to the se......
Procedure for metallographic identification of inclusions (qualitative)
Procedure for Precious Metal Authentication by Attached Materials (Qualitative)
This document explains the standard procedure for authenticating a precious metal using attached materials. This procedure is intended to be used as a qualitative assessment only, and is not intended to be a replaceme......
Method for revealing the microstructure of metallographic specimens-chemical etching
Introduction
In microscopy, several approaches can be used to memorize substances in tiny specimen. These include physical approaches such as phase contrast, stereomicroscopy and fluorescence as well as chemical techniques such as staining. Common staining techniques including aldehyde fuchsin, t......
SUS316L (00Cr17Ni14Mo2) fracture and related cracks
INTRODUCTION
SUS316L (00Cr17Ni14Mo2) is an austenitic stainless steel with good overall corrosion resistance, particularly to pitting and crevice corrosion in chloride environments. It is an alloy with low carbon content for general use and light gauge stainless steel applications. The low carbon......
