Boiler Quality or Pressure Vessel Plates are produce to make a superior quality carbon steel plate which have consistent controlled properties and are designed to withstand the internal pressure of pressure vessels, boilers and valves . Boiler quality or Pressure Vessel Steel Plates are very popular due to its diversity of use and longevity. Characteristics Uniform surfaceHigh tensile strengthCorrosion resistanceSturdy constructionTemperature resistance.

ASTM A 516 or ASME SA 516 grade is one of the most popular steel grades.

It is primarily intended for use in welded pressure vessels where notch toughness is important.These grades cover a range of tensile strengths from 55 - 90 MPa and this versatility explains much of the specifications popularity. 

For plates thinner than 40mm normally supply as rolled. Plates above 40mm thick are normalised. For A 516 grade 70, which is one of most popular steels, the ASME standard composition is as follows (dependent on grade).

ASTM A516 Standard steel plates are intended for use in pressure vessels where increased strength is is important.

Boiler Quality steel is used in areas where there is likely to be a high degree of Boiler Quality or Boiler Quality of the steel plate. Typical applications are in truck beds, attachments to diggers and earth movers and in processing applications in the mining industry. 

The key quality for Boiler Quality steels is their hardness. We sell Boiler Quality plate according to its hardness measured on the Brinnell Hardness Test - usually in 400HB and 500HB grades. If your specification is to the Rockwell Test we can also advise. 

Steels with a high HB rating (Brinell hardness) are intended for applications where Boiler Quality or Boiler Quality resistance is important. The benefit of using an Boiler Quality steel is that that the plant, machinery or constructions working life can be extended considerably. This can significantly improve the reliability, durability and safety of structures and equipment. It also helps to reduce the maintenance costs associated with Boiler Quality and breakdown of plant. 

400 HB steel is over 3 times harder than mild steel (120HB), but only a third as hard as stainless steel (1250HB). Example uses are for construction machinery, skips, bulldozers and excavators, buckets and conveyors. 

The steel is quenched which provides Boiler Quality resistance; in order to improve hardness it may also be tempered. Lower HB's generally provide good cold bending properties and good weld ability. Weld ability is not generally reduced as the hardness increases.
