Sir,

I am interested in knowing the equivalent material for AISI 602 piping /tubing material.
The details of the AISI 602 are as mentioned below.

Chemical composition
Element Composition(%)
C 0.20-0.33
Mn 0.45-0.65
Si 0.55-0.75
P 0.04 Max
Cr 1.00-1.50
Mo 0.40-0.60
V 0.2-0.30


Tensile strength- 130-260 Ksi
Yield Strength -110-200 Ksi
% of Elongation – 10 Min.
% Reduction in area -40-60

Can Anyone here please guide me that whats the API or ASME code that governs inspection of FRP vessels.
In addition to this, If any Article/ Document, that you can suggest me to study.

Hello: I am finishing a PhD Thesis within Manufacturing Engineering Department of UNED University in Spain. In my Thesis, I analyze the impact generated by Manufacturing Code selection (ASME B&PV and KTA Rules) on nuclear pressure-vessels manufacturing. For this issue, I developed an algorithm to "quantify" the Stringency Level of some requirements of materials (chemical, mechanical and fatigue) specified in these Standards/Codes. An important part of this work is, the assignment of relative weights for each requirement of the materials (SA-508/SA-533 and DIN 20MnMoNi55 described by KTA 3201.1). I have formed a panel of High Level experts in pressure vessels manufacturing and materials. And I would like to ask for your collaboration I just would need your dedication for 5 minutes to choose one of three options included in a short questionnaire. I would be very grateful if you could dedicate these 5 minutes. If you want i could send this questionnaire by e-mail to you. Might you help me? Thanks a lot in advance, Álvaro R.

As per ASME sec VIII, is PWHT mandatory for pressure vessels with lethal service made from cladded carbon steel with thickness below 32mm?

I'm doing my project in gear manufacturing using composite materials. For this project i need mechanical properties of materials mentioned below. PROJECT TILE : RETROFITTING OF LATHE MACHINE GEAR TRAIN USING COMPOSITE MATERIAL AND STUDY AND ITS PERFORMANCE. 2024+al2o3 2024+sic 7075+al2o3 7075+sic
