Does Portland Bolt manufacture bolts from 44W steel?
Yes. 44W / 300W is the Canadian version of A36 steel, and is a grade within the CSA G40.21-04 specification. The Canadian Standards Association specification G40.21 covers structural quality steel plates, shapes, sheet, sheet piling, cold-formed channels, hollow sections, Z sections, and bars. 44W steel has slightly higher mechanical requirements than A36, which are summarized in the chart below. The “44” designates the minimum yield strength of the steel (44 ksi) and is sometimes referred to by its metric equivalent, 300W, in which the 300 refers to the minimum yield strength in megapascal (MPa).
|Mechanical properties||44W / 300W||A36|
|Tensile||65 to 85 ksi||58 to 80 ksi|
|Yield||44 ksi min||36 ksi min|
|Elongation||20% min in 8″, 23% min in 2″||18% min in 8″, 21% min in 2″|
All of Portland Bolts mild steel round bar is rolled to meet both A36 and 44W and is the mill test reports carry a dual certification. We commonly manufacture bolts and fasteners to the 44W specification. Last year we shipped product to 8 of the 10 provinces in Canada and we average over 5 Canadian shipments per week.
