| titleOfInvention | Steel wire for cold-formed spring excellent in corrosion resistance and method for producing the same |
| abstract | The present invention relates to a steel wire for cold forming spring containing a chemical composition defined in advance, Martensite transformation start temperature M S1 represented by the following formula (1) is in the temperature range of 280 ℃ ~ 380 ℃; The austenite grain size number of the austenite lip is No. 12 or more; The occupancy ratio of the carbide grains deposited along the grain boundaries of the austenite grains is 50% or less; The amount of residual austenite remaining after austenitization and tempering is 20% by volume or less; The tensile strength is at least 2,000 MPa;n n n M S1 = 550-361 [C]-39 [Mn]-20 [Cr] ‥‥ (1)n n n (Where [C], [Mn] and [Cr] represent the mass% of C, Mn and Cr, respectively)n n n The steel wire ensures hot-rolling formability and subsequent pullability while oriented to high strength and high stress; Furthermore shows good corrosion resistance; Fatigue strength as a basic characteristic is also a steel wire that can obtain a good spring (mainly automotive gas springs). |
