AL2 化学元素成分含量(%)

成分	C	Si	Mn	P	S	Cr ^②	Ni ^②	Cu ^②	Mo ^②	其他合计
最小值	-	-	-	-	-	-	-	-	-	-
最大值	0.25	0.6	1.2	0.04	0.04	0.3	0.4	0.3	0.15	0.8

其他单个或其他合计化学成分包括表中未指定值的化学成分。只有在假定存在或在常规分析中，且有迹象表明其成分将超过规定值的情况下，才应进行分析。

①碳含量每降低0.01%，最大锰含量则增加0.04%，允许最大锰含量到1.4%
②残余元素。

AL2 机械性能

热处理或状态	抗拉强度 σ_b Mpa	屈服点 σ_s Mpa	断后伸长率或延伸率 δ %	冲击吸收能量 KV2 J
N或N+T或OQ+T或WQ+T	485~655	≥275	≥22	-46°C ≥20

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.

表中值适用于铸件截面厚度小于等于500mm，超过此尺寸的机械性能应与制造商协商。
