Re: [PSUBS-MAILIST] k350 plans

Hi Glen,

There is NO PIPE OR TUBING available in A516-Grade 70 steel. It is only available in plate and must be rolled to shape.

Best Regards,

Jim K

Hi Glen,

I'm not a K boat owner, but I am sure the steel spec. stands for ASTM A516 - Grade 70 steel That is the most comonly used and spec'ed steel for subs because of it's higher quality and ability to have good properties in colder situations.

After much discussion and consideration, it is the material I chose to use on my sub. Unfortunately, it is only available in plate form and has risen in price more than most other more common steel plates. .

Best Regards,

Jim Kocourek
