B6 機械性能

熱處理或狀態(tài)	抗拉強度 σ_b Mpa	屈服點 σ_s Mpa	斷后伸長率或延伸率 δ %
N+T或OQ+T或WQ+T(T 720°C max)	≥620	≥420	≥13

A=for anneal by heating to a temperature above the AC3 and cool in the furnace
N=for normalize by heating to a temperature above the AC3 and cool in still air
OQ=for quench into oil from a temperature above the AC3
WQ=for quench into water from a temperature above the AC3
AH=for air harden by heating to a temperature above the AC3 and cool in air at a rate fast enough to produce a hardened microstructure
T=for temper by heating to a temperature below AC1
ST=for solution treat by heating to temperature high enough to dissolve and any intermetallic phases followed by a rapid cool.
