Product Q&A

Q:Difference between Q235A and Q235B?

Q235A does not require impact test, Q235B requires 20C impact energy >=27J. Q235B has more stable quality, suitable for welded structures and dynamic load members. General structure Q235A, important/welded structure Q235B. We stock Q235B.

Q:How to choose between Q235 and Q355?

Q235 yield 235MPa, good ductility/weldability, low price, general structure; Q355 yield 355MPa, 50% higher strength, long-span heavy load structure. Same load Q355 saves 20-30% material.

Q:Can carbon structural steel be quenched?

Q235 low carbon (<=0.22%), quenching effect not obvious, generally not quenched. For higher hardness, carburizing quenching (case hardening) or select 45#/40Cr medium carbon steel.

Q:How to calculate weight?

Round = diameter2 x 0.00617 kg/m; Square = side2 x 0.00785; Flat = width x thickness x 0.00785.

Q:MOQ and lead time?

Stock 1 tonne MOQ 3-7 days, special custom rolling 3 tonnes MOQ 15-30 days.
