Re: [MW:17933] Linear indications on H beam

 Dear all,
Do one sample for mechanical and chemical test. if it is meeting the requirement of material standard ,then you can use it.
check one sample after blasting the line mark is visible or not.

Hi,

We did UT and there is no lamination defect. the indication can be found only on the surface of the H Beam and is about 2mm deep on the whole surface.

Kindly

Dear Joe, 
           In my suggestion, 1st u will do UT in that specify area, whether if it is a lamination found is rejected , due to some material problem will come sometimes. (or) the lamination is not found means it is easily repairable.....

Thanks..

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

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...
