Re: [MW:29081] Hardness for SA516 Grade 70

I was looking for that data in the Code, I could not find it, hopefully someone has better luck and share the hardness data of this steel, with reference to the standard; On the other hand, when a pressure vessel carries the ASME stamp, the Authorized Inspector of the Authorized Inspection Agency necessarily has to intervene with your company has a contract, the Authorized Inspector has the obligation to advise and give you technical support.

PWHT is followed spec, and WPS should be shown hardness test value.

Subject: [MW:29073] Hardness for SA516 Grade 70

For a pressure vessel designed with stamped under ASME VIII Div.1, there is a requirement that: "Hardness values should not exceed 200 brinell for the welds / material of shell."

Shell material is specified as SA516 Grade 70.

I am concerned the requirements for hardness and material will automatically require stress relief for all pressure vessel parts.

Would SA516 Grade 70 have hardness lower than 200 Brinell?

Thank you.

RKD

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...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
