The Ugly TRUTH About Cast Iron Boilers

Cast iron is basically steel with a high level of carbon impurities and carbon doesn’t translate into longer boiler life. Cast iron is a brittle material which can fracture under temperature shock. It’s well known that it is common for today’s cast iron boilers to have cracked sections, cracked burner doors, leaking gaskets, and leaking tankless coil flange.

A Brief History of Boilers | Rite Engineering

Cast iron was a good metal to make low pressure steam boilers out of for four reasons: It was relatively cheap. It could be cast into shapes. It’s tensile strength was strong enough for it to be used for low pressure steam (although not high pressure steam). And cast iron was more resistant to oxygen corrosion than steel.

Water Handbook - Preboiler & Industrial Boiler Corrosion

Hydrogen embrittlement of mild steel boiler tubing occurs in high-pressure boilers when atomic hydrogen forms at the boiler tube surface as a result of corrosion. Hydrogen permeates the tube metal, where it can react with iron carbides to form methane gas, or with other hydrogen atoms to form hydrogen gas.

Boiler Heat Exchanger: Aluminum vs Cast Iron vs Stainless Steel

As you shop for boilers and read their specifications, you’ll see three materials used in heat exchangers: cast iron, aluminum and stainless steel. The heat exchanger is the part that transfers heat from the combustion gases into the water that is being circulated by the boiler, so it is a crucial part of the design.

Boiler (power generation) - Wikipedia

Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required.
