ASME A455 CAN IT TAKE HEAT?

[WOODBOILER]

Will ASME A455 TAKE 1200-1400 DEGREES F?
If I cut a 500 gal propane tank in half and use it as the fire box in a wood boiler will it handle the heat? Generally 5/16 to 3/8 thick. Also does anyone know if all propane tanks made since the ASME standards for pressure vessels came out in 1932 are made from A455? Thanks for your time,

WOODBOILER;
ASME SA 455 is a standard specification for pressure vessel quality carbon steel plate that contains manganese for higher strength, in comparison to conventional carbon steel plates.

Will it take the heat? Well, it won't melt but it will warp and oxidize over time and you will be left with paper thin plate. What you need would be a low alloy steel plate, like SA 387 Grade 11 or 22 that is suitable for elevated temperature service. The SA 455 plate material is not intended to be used at service temperatures above 1000 deg F. It is designed for use at ambient temperature service to take advantage of higher strength properties over conventional pressure vessel quality carbon steel plate so that a thinner vessel wall can be used to save weight.

I would like to caution you about cutting a propane tank. I have been privy to the after effects of two explosions of opened and cleaned 100 gal propane storage tanks. The supposedly clean tanks exploded about the time the torch burnt through the shell. In one case the participants had cut numerous tanks to make grills and smokers. They cut one too many as the last one took the life of the shop owner.
The second one was an individual for some reason decided to cut up a propane storage tank. From all indications all he did was wash it out with water. The explosion made him vegetable so the true story will never be recorded.

It was determined that the culprit in the explosion was a bacterial slime in the bottom of the tanks which upon heating liberated enough propane to cause an explosion.

Another potential hazard of propane tanks is the mercaptan used for odorizing the gas. The sulfur can stay behind even in a "cleaned" tank. If allowed to set over a period of time it will begin to corrode the carbon steel liberating explosive hydrogen gas.
