Re: [MW:13259] Surface roughness measurement instruments.

By Materials & Welding
Dear Mr. Rao,

There are portable surface roughness measuring instruments to measure as required.

UK based Rank Taylor Hobson instruments are available in India.

Subject: [MW:13256] Surface roughness measurement instruments.

Dear Experts,

I work as inspection Engineer. When i go for Blasting inspection, contractor provided  me profile comparator for surface roughness measurement.

Contractor do  Grit blasting in the shop.

I need to measure surface roughness  -  75-100 microns      Painting system No#1
                                                            50-75 microns        Painting system No#2

Queries

Q 1: Comparator is enough for surface roughness measurements.

Q2: Is any other tools available for roughness measurement?.

Q3:  What is the normal industry practice.


Pl. provide your valuable suggestions as i'm new for painting activities.

Rao.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
