Mechanical Behavior of High-Strength Bolted Joints Fabricated from Fire-Resistant Steel at Elevated Temperatures

Table 2

Mechanical behavior the fire-resistant steel plate.

Thickness/mm	Rp0.2 (MPa)	Rm (MPa)	Elongation A (%)	Yield-to-tensile strength ratio	180° cold-bending	Impact energy at −40°C Akv/J	Yield strength held at 600°C for 180 min (MPa)
10	490	636	23.5	0.77	D = 3a	353	345

Note. D is the diameter of the bending indenter and a is the thickness of the fire-resistant steel.
