[MW:34584] Required chemical composition for carbon & low-allot steel and stainless steel per NACE MR0175/2021

By Materials & Welding

Hi experts,

 

This is related to chemical composition of carbon and low alloy steel per NACE MR0175-2021

Chemical composition for carbon and low alloy steel

Per Clause A.2.1.2 - Carbon & low-alloy steel are acceptable at 22 HRC max. hardness provided they contain less than 1% mass fraction Nickel.

Per Clause 8 -    Max. acceptable level for flat-rolled produce is 0.003% mass fraction of sulfur

Max. acceptable level for seamless product is 0.01% mass fraction of sulfur

Conventional forgings with sulfur levels less than 0.025% mass fraction and castings are not considered sensitive to HIC and SOHIC

 

Is this the only minimum required chemical composition for carbon & low-alloy steel?

Can you please suggest the clause for chemical composition for stainless steels as well?


Regards,

Akash Wagh.

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...
