Folks,
Do you have any problems (cracking issues) with A203 aluminum alloy after heat treatment? I try different cooling cycles but either is cracking (hot water), or does not meet the mech. properties (air). Also I have recommendation to use Helium or Argon (too expensive, but it works). Any...
Folks,
I have a question from one of my customers. They are building commercial/residential boilers and are interested if it is any possibility of reaction between brass and aluminum alloys or stainless steel, brass and aluminum alloys. The boiler body is made of aluminum and he wants to use...
Is AWS D17.1 -2001 replacing AMS - STD - 1595 (MIL - STD 1595) or is just an addition/duplication of requirements for the aerospace part manufacturers? I haven't seen anywhere any notes ( in the body of the spec) where this spec supersedes any other specs; (speaking with different welding...
I need a little help to find data regarding the % austenite in 17-4PH and mechanical properties. Any recommendations are appreciated.(books, articles, etc.)
Question:
Can I qualify a welder for casting weld repair from Carbon and Alloy steel, in accordance with AWS D17.1:2001 (or former AMS/MIL-STD1595) using 8620 Heat Treatable Alloy Steel instead of any steels from group IB table 4.2 (or in AMS 1595 para 10.2 in the Appendix, page 61 Base metal...
Any recommended cast materials (Ni or Co base) to use for the oilfield drilling (turbodrilling motors) with similar properties to BS3146 Part 1 CLA 11 (nitriding steel)?
Any recommended cast materials (Ni or Co base) to use for the oilfield drilling (turbodrilling motors) with similar properties to BS3146 Part 1 CLA 11 (nitriding steel)?
Could anybody give me a reference about BS 3146 and equivalences? I am interested specific for the BS 3146 Part 1 Cla 11. What steel will be equivalent (AISI, ASTM, AMS, etc.). Also, I have a reference for "15 ND8" treated material.
Thank you
