JIS G3114 SMA50 AW steel JIS G3114 SMA50 AW steel is a structural weathering steel; JIS G3114 SMA50 AW steel is also referred to as atmospheric corrosion resistant steel. JIS G3114 SMA50 AW steel has a widely use in Mine fans, earth moving buckets, trailers and large road vehicles, drill rings, cranes, excavators, underground mining equipment, bridges and other high strength components requiring superior toughness.

JIS G3114 SMA50 AW steel Chemical Composition by [%]

C	Si	Mn	P	S	Cr	N	Cu	CEV
Max 0.16	Max 0.5	0.5 - 1.5	Max 0.035	Max 0.035	0.4 -0.8	Max 0.009	0.25-0.55	Max 0.52

JIS G3114 SMA50 AW steel chemical composition can increase resistance to atmospheric corrosion compared to other steels. This is because it forms a protective layer on SMA 50 AW steel surface under the influence of the weather, So which could more accurately be termed as an "Atmospheric Corrosion Resistant Steel".
