What is the effect of thickness on performance?
The greater the thickness, the slightly lower the yield strength/tensile strength and the slightly lower the elongation.
What is the hardness range of Q235?
HB100-130, low hardness, easy to cut/drill/bend.
What are the applicable scenarios for Q235A?
Room temperature static load, non-welded, secondary components (embedded parts, pads, non-load-bearing supports).
What are the applicable scenarios for Q235B?
Room temperature welding, load-bearing components (steel beams, steel columns, purlins, stairs, scaffolding), most commonly used in engineering.
What are the applicable scenarios for Q235C?
Around 0℃, important welded structures (outdoor in northern winters, low-temperature factories).
