Welded/Wrought Pipe High Yield Carbon Steel 60 KSI Yield Strength
The Russian GOST standard equivalent to ASTM A615 Grade 60 reinforced steel rebar is GOST 5781-82, specifically the steel grade A500C. This standard specifies the requirements for hot-rolled steel bars used in concrete reinforcement, similar to the properties defined in ASTM A615. The GOST rebar typically has a yield strength of 500 MPa, aligning closely with the Grade 60 designation in the ASTM standard.
Why would you reject material that overperformed its tensile-strength specs? The standard for Concrete Reinforcement rebar,astm-615a Grade 60 (60,000 PSI minimum yield strength)
To determine if the cement satisfies ASTM standard requirements for initial setting time, you must compare the measured setting time of the cement with the specific limits outlined in the relevant ASTM standard (such as ASTM C191 for hydraulic cement). Generally, the initial setting time should not exceed 60 minutes for most types of hydraulic cement. If the measured setting time falls within this range, then it meets the standard; otherwise, it does not. Always refer to the specific ASTM standard for the exact requirements applicable to the type of cement being evaluated.
The equivalent ASTM material for BS 1501-213 GR 30B is typically ASTM A516 Grade 60. Both are carbon steel plates used for pressure vessels and boilers, with similar mechanical properties and chemical compositions. However, it is always recommended to verify compatibility based on specific project requirements and standards.
I believe it is called the UH 60 Black Hawk

In my point you, every 60 degree the welding was carry on.

ASTM 1011 comes in many grades which determine the yield strength ie:1011 gr 42 would have a min yield of 42,000 psi

A full minute is 60 seconds, so 39 sec = 39/60 minute = 13/20 minute, in simplest form. It is 0.65 minutes in decimal.
49/60 in decimal form = 0.816749/60:= 49 ÷ 60= 0.8167 in decimal
41/60 is in its simplest form.
There are 360 degrees in a full circle. 60 minutes in 1 degree 60 seconds in 1 minute Therefore: 360 x 60 x 60 = 1,296,000 seconds
There are 900,000/24*60*60 = 10 full days
