i have just found a webpage(http://www.qualityforgings.co.uk/spec_4130-80.htm) in which there are some proporties data such as "HEAT TREATED AND TESTED TO: Tensile - 100,000 PSI (690 N/mm2),Yield - 80,000 PSI (552 Nmm2),Elongation in 2"L - 18%, Reduction of Area - 35%",if i can consider these...

thanks for the help. as metengr said it's different to find the mechanical properties of the impeller material (for the compressor not for the pump),but i want to know the Minimum Tensile Properties that AISI4130/4140 standard specification specified, how can i find it ?

i am trying to do a failure analysis for the impeller made of AISI4130/4140(forging), but i don't know the proporties in the standard specification ,anyone can help me? thanks.

I need some advice. What is the effect on the fatigue of 304SS severely deformed?

thank you Metalguy I have some difficulies to express in english,let me try it again the vessel with peddler:maybe I should say agitated vessel.dia.of the vessel is 2000mm.rotate speed of agitator is 50rpm. pudding is wrong, here shoud be agitating. I mean if the corrosion is related with...

I have a question about the low carbon steel vessel, 16mm wall thickness in which there is a peddler. The vessel was heated by burning oil. The medium is caustic soda with some sodium sulfite, temperature is 330-350¡æ, normal pressure. The vessel was badly corroded locally using for about 30...

can anyone help me to find the data of aluminium melting point such as 6063? thank you chenjin

I plan to do some intergranular corrosion test for 316L stainless steel plate rewelded for 5 times in the same position. As we know, rewelding may cause carbide and sigma phase precipitating and resulting in corrosion resistance decrease. According to ASTM A262, method E may be used to access...
