[MW:16591] Re: Standard Reference for Hardness of A 516 Gr.70

By Materials & Welding
Dear All,

In addition to trailing mail.

The Vessel is used for storage of Helium liquid.

The PWHT was done according to UCS-56.

The Thk. of Shell & d/e are 40 & 50mm respectively.

The clients wants to know acceptance reference standard of Hradness.

We checked after PWHT & found in range from 150 to 200 HB.

Please provide reference acceptance standard for the Hardness to convince client.

Awaiting your reply.

Regards,
Vikas Rana

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...
