Aug 24,2017·Key Difference Polycarbonate vs ABS Polycarbonate and ABS are widely used thermoplastic elastomers and have their unique set of properties.These properties have made these polymers to be used in wide range of applications.The key difference between polycarbonate and ABS is that polycarbonate is an amorphous polymer made from melt polycondensation of bisphenol A andDifference Between Steel and Mild Steel Difference BetweenSteel vs.Mild Steel.What is the difference between steel and mild steel? One might think that its all in the name,but this is most certainly not the case.There are significant differences between steel and mild steel,which will be discussed in this article.But before we get to the important bits,why is it important for people to know the difference between the two?Google Sheets Free Online Spreadsheets for Personal UseGoogle Sheets makes your data pop with colorful charts and graphs.Built-in formulas,pivot tables and conditional formatting options save time and simplify common spreadsheet tasks.

The main differences between pregalvanized sheet and post fabrication galvanized are that pregalv is very flat sheet (having been stretch leveled during the process) and with thin coating.Post galv more likely to have some distortion,not be float,and have much thicker coating.The thicker the coating the more the so called self healing effect.Resistance Spot Welding of CRCA Steel sheets using surface Feb 25,2016·To simulate the resistance experienced during actual welding,measurements are taken with two CRCA steel sheets between the electrodes held together without welding current held under pressure.Average resistance was obtained by three random measurements for uncoated and coated electrodes at different positions,respectively.Resistance Welding Spot,Seam and Projection Welding(i) Thicker sheet has higher resistance (R = 1/a,more thickness means longer 1,therefore higher R,as resistivity () of the material is constant at a given temperature) or lower conductivity (),( =)/and the nugget tends to penetrate deeper into it.Therefore use bigger diameter electrode on the side of the thicker sheet.
Sheet metal design guidelines are followed to design quality sheet metal enclosures.This helps in delivering the product at low cost and faster timelines.All sheet metal design guidelines are very difficult to follow in complex sheet metal parts..Therefore exceptions can be there for complex sheet metal parts.Sheet Metal Gauge Chart Metal Supermarkets - Steel Feb 01,2018·When working with sheet metal,it is common for the term gauge to be used.Someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel,for example.To help,this blog will explain the gauge system and features a sheet metal gauge chart.Sheet Metal Gauge Tolerances Chart Engineers Edge www Sheet Metal Guage Tolerances During the rolling process the rollers bow slightly,which results in the sheets being thinner on the edges.The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the Manufacturer's Standard Gauge,which has no inherent tolerances.
What is recommended inside bending radius in sheet metal fabrication? For hard materials (CRCA and stainless steel),Minimum inside radius is 0.7 times of sheet thickness.For softer materials (for example Aluminium) the minimum inside radius is equal to sheet thickness.Click this link to know more about sheet metal bending Operations.Similarities and Differences between Flu and COVID-19 CDCMore information about differences between flu and COVID-19 is available in the different sections below.Because some of the symptoms of flu and COVID-19 are similar,it may be hard to tell the difference between them based on symptoms alone,andSome results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
