当量圆直径在0.2~3微米的存在密度为1个/微米 The present invention provides a high strength with excellent wound of spring wire, characterized by containing, by mass%, C: 0.75 ~ 0.85%, Si: 1.5 ~ 2.5%, Mn: 0.5 ~ 1.0%, Cr: 0.3 ~ 1.0%, P: 0.015% or less, S: 0.015% or less, N...
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. ...
A heat-treatment steel for springs which is to be subjected to cold coiling, can combine sufficient atmospheric strength with coilability, and has a tensile strength of 2,000 MPa or higher. Through a heat treatment after spring formation, the steel can heighten performances required of springs....
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...
Heat treating:(as done by Paul Bos) AST-34 is a secondary hardening steel. That means it gets harder with the freezing and tempering, usually gaining 2 -3 Rc points. Heat to 1975 ℉and soak for 40 minutes. Quench in Argon or rapid quench in air, straighten as necessary before freezing...
