Re: [MW:10793] Impact testing temp. for EN19 steel

By Materials & Welding
Dear Sir,
            If the application is room temperature, the test temperature shall be 0°C; due to safety factors.
Regarding casting and plate, plate has better properties than casting as it is rolled and grains are more aligned with fine grain 7 to 8. In casting, if u can demonstrate a ASTM grain size of 5 or greater, u can very well use the casting tooooo.

Dear Friends

I wanted to use EN 19 plate in one of my present project, wherein the application demands severe impact loads at room temperature.

I had browsed through the properties of EN 19 plate in various literatures wherein the Izod test values are mentioned @ 55J.

However the Izod testing temperature is not mentioned.

Can anyone help me out or guide me where to refer, so that i can know the Izod testing temperature of this EN 19 steel.

Secondly i would also like to know which of the two will have more toughness and why - EN 19 casting OR EN19 plate ?
The reason being the final component will have to be casted due geometrical complications.


Regards

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...
