STEEL CORD FOR PROTECTION PLIES OF PNEUMATIC TIRES
Abstract:
A steel cord (10) particularly adapted for reinforcement of a protection ply in a tire has under compression in rubber a deformation Wk at instability of at least 3% and is stress-relieved so that its total elongation at rupture in rubber exceeds 3.5%. The steel cord (10) comprises steel filaments (12) having a pearlitic structure.
Abstract(Chinese):

特别适用于加强轮胎中的保护层的钢丝帘线（10）在橡胶中受到压缩，变形Wk在不稳定性下至少为3％，并被应力释放，使得橡胶中的总伸长率超过3.5％。 钢帘线（10）包括具有珠光体结构的钢丝（12）。
