HC260B Mechanical Properties

Tensile Strength σ_b Mpa	Yield Point σ_s Mpa	Elongation or Extension Rate δ %
360~440	260~320	≥29(A80)

ⓐ A50、A80-gauge length；t-nominal thickness/mm

① The sample is P6 in GB/T 228.1, and the direction of the sample is transverse.
② When the nominal thickness of the product is greater than 0.5mm, but not greater than 0.7mm, the elongation after breaking is allowed to decrease by 2%; When the nominal thickness of the product is not greater than 0.5mm, the elongation after breaking is allowed to decrease by 4%
③ Bake hardening (BH₂) not less than 30MPa.
④ When the thickness is greater than 1.2mm, the BH₂ value needs to be negotiated separately.
