<div>Both HY-80 and HY 100 are difficult to form and, most problematical,
require special welding procedures - quite different than 516 or other mild
steels. If you plan to certify, then the certification agency must review and
accept the detailed weld procedure and will ask for weld coupons that have been
tested and passed. When we first started using high strength steels it took our
weld guys several months of trying the procedures they had been advised to use
and to, finally, develop their own version of a technique that would pass the
required tests. We were only able to find one supplier of HY80/100 in north
America and they were uber expensive. We also had to fly a certified surveyor in
to the mill to stamp the steel sheets with his mark– and then,
later, to transfer the marks when we cut the steel prior to forming.

<div dir="ltr">I've always heard HY-100 is quite susceptible to cracking, and thus
much harder to fabricate.

<div>So the tinsel strength of HY-80 is 80,000 psi and HY-100 is 100,000 psi,
makes since. Why does Phil Nuytten go with HY-80 on the deep worker 3000? It
would seem like you would want to go with HY-100 just for added safety.
Perhaps HY-100 is harder to weld or more expensive?</div>

<div>A little update on my research. I have not given up on HY-80 or HY-100
compared to 516 gr70. I finally found a very good supplier for HY-80 -
HY-100. I am getting over the hurdles of finding this stuff, the next hurdle
is the welding part of it. Still learning, but can someone tell me the
differences in HY-80 compared to HY-100? </div>
