Through a heat treatment after spring formation, the steel can heighten performances required of springs. The heat-treatment steel for high-strength springs is characterized by containing, in terms of mass%, 0.4-0.9% C, 1.7-3.0% Si, and 0.1-2.0% Mn, the amount of N being 0.007% or less...
摘要: Mechanical properties and the microstructure of different heat treatment spring steel 51CrV4 were studied.By the method of orthogonal,the best heat treatment parameters of spring steel 51CrV4 are as below,880℃ oil quenching-460℃ tempered air-cooled heat for 2 hours.关键词:...
The high-temperature relaxation resistance of spring steel is improved by providing a specified composition of the steel, and subjecting that steel composition to a controlled heat treatment. The high-temperature relaxation resistance, which can not be estimated from the mechanical properties (e.g. ...
The present invention provides spring steel used for spring steel wire achieving both high strength and cold coilability and spring steel wire, that is, spring steel containing, by mass%, C: 0.45 to 0.70%, Si: 1.0 to 3.0%, Mn: 0.05 to 2.0%, P: 0.015% or less, S: 0.015% or less...
High for strength spring drawing heat treated steel wire and high strength drawing before a spring steel wire the circle equivalent diameter of undissolved spherical carbides is less than 0.2 [mu] m, drawn heat treated steel wire for high strength spring I will... 雅之 橋村,橋村 雅之,千田...
The subject mainly studies the relation between heat treatment of 60Si 2CrVA Spring Steel and properties ,by adopting the quench in different heating times and performing tempering experiments under different temperatures .We could measure its HRC and mechanical properties accessments ,observe its micro...
